Greg’s Red Lager

Posted on by

My dad got me started in homebrewing (and he has been brewing for over 50 years!), so it’s always fun to brew together when I’m back home. Planning for a recent session, he mentioned that he would like to make a red lager following a recipe he had previously made. His old version, though, was extract, and he now brews all-grain, so a conversion was in order.

The original version, of unknown origin, called for the following:

  • Red Lager (extract version)
    • 8oz. dark crystal malt (75-85L)
    • 8oz. med. crystal malt (50-60L)
    • 5.5lb. DME
    • 0.75 oz. Cascade, 45 minute boil
    • 0.25 oz. Cascade, 15 minute boil
    • Lager Yeast
  • Notes
    • “I think it was the lightest DME I could get at the time. Starting gravity was 1.042. I think I would like the S.G. to be about 1.050.”
    • Hops are whole, homegrown Cascade hops – a past test showed around 5.5% alpha

The conversion was pretty straightforward. I subbed in pilsner malt for the DME, adjusting to hit the target gravity, and used crystal 60 and crystal 80. According to BeerSmith, the color was a little lighter than a “red” lager, so I added a tiny bit of roasted barley for reddish color adjustment.

Although Dad and I planned to brew a five gallon batch, I wanted to test it with a 2.5 gallon batch first.

Greg’s Red Lager (2.5 gallon batch)

  • 5 lb. Synergy Select Pilsen malt (Briess)
  • 4 oz. 80L caramel malt (Briess)
  • 4 oz. 80L crystal malt (Great Western)
  • 0.5 oz. roasted barley (Crisp)
  • 0.35 oz. Cascade whole hops (est. 5.5% alpha), 60 minute boil
  • 0.25 oz. Cascade whole hops (est. 5.5% alpha), 10 minute boil
  • 0.25 tsp. BrewTanB, 10 minute boil
  • 0.5 Kick carrageenan tablet
  • 1 pkg. Diamond lager yeast (Lallemand)

Target Parameters

  • 60 minute infusion mash, 149°, full volume mash
  • 1.051 o.g., 1.007 f.g., 5.8% abv, 16 IBU, 13 SRM
  • Claremont tap water; 110 ppm Ca, 8 ppm Mg, 97 ppm Na, 75 ppm sulfate, 110 ppm Cl, 132 ppm bicarbonate
  • 2.5 gallon batch

Procedure

  • I heated 3.9 gallons of water to .154°, adding a Campden tablet to remove chloramines. I then added the grains and 2 mL of 88% lactic acid to adjust pH, and then held it at 149° while recirculating for 60 minutes. Next, I raised the temperature to 168° for 10 minutes before pulling the grains.
  • In total, I collected 3.5 gallons of runnings with a gravity of 1.043, for 72% mash efficiency.
  • I brought the runnings to a boil, adding hops and finings per the recipe. After 60 minutes, I turned off the heat and chilled to 85° before transferring to the fermenter, chilled to 68°, and then pitched the yeast. I continued to chill down to 53° in the fermentation chamber.
  • Starting gravity was 1.053. I brewed this beer on 8 May 2026.
  • I raised the beer to 54° on 10 May 2026, and then to ambient on 23 May 2026.
  • I kegged the beer on 27 May 2026, using an open transfer and adding 3 oz. of corn sugar to carbonate in the keg.
  • Final gravity was 1.011, for 5.5% abv.
  • I found the pressure to be 32 psi at 70° on 5 June 2026 – perfect.
  • At this point, I transferred the beer to the conditioning chamber, in order to lager.

Tasting

  • Appearance
    • Brilliantly clear, reddish amber beer, with a modest, reasonably persistent ivory-colored head.
  • Aroma
    • Caramel malty aroma at a medium-low level; no hop or yeast character to speak of.
  • Flavor
    • Light caramel flavor; dried fruit at a very slight level. Medium level of bitterness.
  • Mouthfeel
    • Medium-light bodied, moderate carbonation, off-dry finish.
  • Would I Brew This Again?
    • This was fun to try as an exercise, and I think it captured the American craft red lager experience of “microbreweries” and homebrewers circa 1996. It’s not my cup of tea as a beer overall; I think a traditional Vienna lager hits some of the same notes but with more drinkability. Even so, this recipe was worth the experience. And Dad enjoyed it, which was the main goal! If I were to do it again for myself, I’d probably dial back the crystal malts by about 50 percent, to lighten up the mouthfeel and flavor.

Artemis Amber Ale

Reply

I frequently state that I love brewing an “old-fashioned” American amber ale, because they’re so hard to find in the wild. Lo and behold, I recently discovered an exceptional example from Highpoint Brewing (San Dimas, California) in their “Uncle’s Red Ale.” Although labeled as an American red ale, I would call it an American amber for BJCP purposes. The beer (sampled from a can) had a nice malty backbone, American “C” hops, and some notes of dark crystal malt (e.g., crystal 120).

Based on my tasting of the commercial example, I wanted to create a hombrewed homage. It needed a good chewy malt backbone, so I split 50/50 on Munich and Maris Otter malts for the base. The crystal malts needed to be on the more carmel, toffee, and roast side, so I split those 50/50 with crystal 80 and crystal 120. To amp up the “C” hop character, I went straight Centennial, with a modest dry hop addition to the fermenter. Yeast was just the basic BRY-97.

I brewed this around the time of the Artemis 2 mission, hence the name. I was inspired to draft a label, using a photo shot by the astronauts on the far side of the moon. Aside from the photo, everything else was created in Inkscape. Ad astra per zymurgiam!

A circular graphic, rimmed by a gold circle. At the bottom, a moonscape from a distance forms a half-visible globe. Text at top in large gold letters says, "Artemis Amber Ale." Below that is a large graphic of a hop cone, floating over the surface of the moon. Text below the hop cone says, "Ad astra per zymurgiam." At the very bottom, text says, "Farke Brewing, Claremont, California"

Artemis Amber Ale

  • 3 lb. Barke Munich malt (Weyermann)
  • 3 lb. Maris Otter pale ale malt (Thomas Fawcett)
  • 0.25 lb. 80L caramel malt (Briess)
  • 0.25 lb. 120L crystal malt (Great Western)
  • 0.3 tsp. BrewTanB, added to mash
  • 0.5 oz. Centennial hop pellets (8.1% alpha), 60 minute boil
  • 0.5 oz. Centennial hop pellets (8.1% alpha), 10 minute boil
  • 0.3 tsp. BrewTanB, 10 minute boil
  • 1 Kick Carrageenan tablet, 5 minute boil
  • 1 pkg. BR-97 American West Coast Ale yeast (Lallemand)
  • 0.5 oz. Centennial hop pellets (8.1% alpha), dry hop in fermenter

Target Parameters

  • 60 minute infusion mash, 152°, full volume mash
  • 1.049 o.g., 1.008 f.g., 5.3% abv, 34 IBU, 14 SRM
  • Claremont tap water, adjusted to .110 ppm Ca, 20 ppm Mg, 97 ppm Na, 121 ppm SO4, 110 ppm Cl, 132 ppm bicarbonate
  • 3 gallon batch

Procedure

  • I took 4.5 gallons of tap water, added a Campden tablet, and added 2 g of epsom salt, while heating to the strike temperature of 157°. I mashed in the grains along with 0.3 tsp. of BrewTanB, and held the mash at 152° for 60 minutes while recirculating. I also added 1 tbs. of 10% phosphoric acid to the mash, to adjust pH.
  • Next, I raised the mash temperature to 168°, held it there for 10 minutes, and then pulled the grains.
  • In total, I collected 4 gallons of runnings with a gravity of 1.042, for 71% mash efficiency.
  • I brought the kettle to a boil, adding hops and finings per the recipe. I boiled for 60 minutes, before turning off the heat and chilling the wort down to 71°. I recently bought the SwirlyArm for my Foundry, which is used to whirlpool in the kettle and improve chilling efficiency; I quite like it.
  • I transferred the wort to the fermenter and pitched the yeast. The fermentation chamber was set at 68°.
  • I brewed the beer on 4 April 2026. Starting gravity was 1.050.
  • On 9 April 2026, I pulled the beer to ambient. It had overflowed through the airlock at some point, so I replaced the airlock. Ambient is ~65°.
  • I added hops on 19 April 2026, and then cold crashed on 20 April 2026.
  • I kegged the beer on 4 May 2026, using 1.8 oz. of corn sugar (the quantity calculated for bottling, not a keg–I’ve had low carbonation on my kegs, so wanted to increase the sugar volume). When I measured the pressure on 15 May 2026, it was at 17 psi, around 2 volumes for the temperature. I cold crashed and finished carbonation with forced CO2.
  • Final gravity was 1.012, for 5.1% abv.

Tasting

  • Appearance
    • Deep copper amber color; slightly hazy; pours with a persistent off-white head.
  • Aroma
    • Amazing! Citrus and pine hop aroma at a medium level. Deep caramel malt aroma at a medium level.
  • Flavor
    • A bitter beer, with a bracing resinous bitterness at the forefront. Moderate caramel and a low level of toffee in the malt. Fermenation profile pretty clean, although I sometimes pick up a bit of fruitiness that might be either from the malt or the yeast.
  • Mouthfeel
    • Medium body, medium carbonation, dry finish.
  • Would I Brew This Again?
    • Yes! This is a great beer; perhaps a touch too bitter, and it needs a little more time to clear the haze (for my preferences). The Centennial and caramel malt combo just works! This beer would be okay with other “C” hops, but because Centennial is so perfect for it I’m hesitant to change that in future batches.

Catharina Sour

The Southern California Homebrewing Festival is coming up! As usual, I can’t make it due to a work event, but I am sending a keg with the Horse Thieves. The “bragging rights” competition this year is tiki-/island-themed beer, so anything that it is tropical/tiki is fair game. Charles, one of our club members and owner of Pacific Brewing Supplies, used an open source machine learning build (“AI”) to analyze a whole ton of recipes and come up with some ideas for our club. One of them was a Catharina Sour, which intrigued me enough to brew it!

Part of the appeal for me was that this is a style I’ve never made previously. Originating in Brazil, the BJCP describes it as “a refreshing fruited sour wheat beer with a vibrant fruit character and a clean lactic acidity.” It is essentially a bright, highly fruited Berliner weisse.

The recipe from Charles was pretty straight-forward, and I made only the most minimal modifications for my equipment and ingredient availability. I kettle soured with Lallemand’s Wildbrew Sour Pitch, and used US-05 (with its famous peachy notes) to provide a subtle fruitiness to enhance the tropical fruit. I chose Amoretti Craft Puree for the base fruit additions, having had good success with it in some batches a few years back. At the suggestion of the recipe, I also used the TrueFruit product (essentially granulated fruit concentrate) to brighten things up in the keg.

Catharina Sour

  • 5 lb. Synergy Select Pilsen Malt (Briess)
  • 4 lb. white wheat malt
  • 0.5 tsp. BrewTanB, added to mash
  • 1 pkg. Wildbrew Sour Pitch (Lallemand), for kettle souring
  • 1.1 oz. Hallertauer whole hops (3.0% estimated alpha), from South Dakota
  • 0.5 tsp. BrewTanB, 10 minute boil
  • 0.5 tsp. WLN1000 yeast nutrient (White Labs)
  • 1 pkg. US-05 Safale American ale yeast (Fermentis)
  • 8 oz. (by weight) mango Amoretti Craft Puree, added to primary
  • 8 oz. (by weight) passionfruit Amoretti Craft Puree, added to primary
  • 1 oz. (by weight) TrueFruit passionfruit, added to keg
  • 0.67 oz. (by weight) TrueFruit mango, added to keg
  • 0.67 oz. (by weight) TrueLime, added to keg

Target Parameters

  • 60 minute infusion mash, 152°, full volume mash
  • 1.044 o.g., 1.009 f.g., 4.5% abv, 4 IBU, 3 SRM
  • Blend of neutralized tap water and RO water to hit 86 ppm Ca, 5 ppm Mg, 64 pm Na, 36 ppn SO4, 86 ppm Cl, 7 ppm bicarbonate, RA=-58.
  • 5.25 gallon batch

Procedure

  • I added 3.9 mL of 88% lactic acid to 5.5 gallons of tap water to remove the bicarbonates, and then added 2.5 gallons of RO water to further reduce the mineral content.
  • I heated the strike water to 157°, added the BrewTanB and grains, and then recirculated at 152° for 60 minutes. Next, I raised the temperature to 168° for a 10 minute mashout.
  • After pulling the grains at the end of the mash, I had 7.1 gallons of runnings with a gravity of 1.035, for 74% mash efficiency. I boiled the wort (without hops) for 5 minutes and then chilled it to 95° before adding 25 mL of 88% lactic acid to adjust the pH of the wort to ~4.2.
  • Before pitching the sour culture, I rehydrated it with 5 g of DME in 100 g of water. My previous experience with dry lacto cultures is that they can clump up, so rehydration seemed wise. Once this was done, I pitched the culture.
  • I did the inital brew on 8 March 2026.
  • Within my Foundry, I held the temperature at 100° for 48 hours, until it hit what tasted like a reasonable level of acidity.
  • I boiled the wort for 60 minutes, adding hops and BrewTanB per the recipe. Then, I chilled the wort down to 70° before pitching the yeast.
  • I pitched the US-05 on 10 March 2026. Around 6 gallons went into the fermenter, with a starting gravity of 1.040.
  • The beer was fermented at 68°. I added the craft puree on 15 March, and also moved the fermenter to ambient at that time.
  • I kegged the beer on 21 March 2026, using 3.15 oz. of corn sugar in the keg. I added the fruit powders directly at this time.
  • Because it was such a large batch, I had some beer left over and bottled it with two carbonation drops in a 22-oz. bottle. The bottle did not get the TrueFruit/TrueLime additions, so is just the “base” fruit style.
  • On 7 April 2026, I measured 16 psi in the keg at 68°, which is around 1.8 volumes of CO2. At this point, I moved the keg to the conditioning chamber, chilled to 34°, and used force carbonation to finish out the beer preparation.
Bottled version
Kegged version

Because I had both a bottled version (with no TrueFruit/TrueLime) and a kegged version (with the additions at kegging), I decided to write up my tasting notes separately.

Tasting – Bottled Version

  • Appearance
    • Light yellow, fairly hazy beer; it pours with a rich white head that subsides fairly quickly and leaves lacing on the glass.
  • Aroma
    • Lightly tart, lightly doughy, moderate tropical fruit aroma that accentuates mango.
  • Flavor
    • Moderately high level of clean lactic acidity; light doughy malt character; medium level of tropical fruit flavor, especially mango, with the passionfruit behind that.
  • Mouthfeel
    • Medium-high carbonation, light body, dry finish.
  • Would I Brew This Again?
    • Yes! This is an awesome sour, one that is complex with the fruit, but not in-your-face. The mango is a little more obvious than the passionfruit; a touch more of the latter would be nice. The fruit quality definitely gets more noticeable as the beer warms.
  • Overall
    • 9/10

Tasting – Kegged Version

  • Appearance
    • Modestly hazy, shimmery, pale yellow beer that pours with a surprisingly persistent white head, which leaves some lacing on the glass.
  • Aroma
    • Bright tropical fruit bouquet at a medium-high level; mango and passionfruit, absolutely! The aroma balance is slightly tilted towards passionfruit. Some lactic sourness comes through, too; light bread dough.
  • Flavor
    • As with the aroma, a bright and fresh tropical fruit flavor is prominent; lime is immediately recognizable, alongside passionfruit. The mango character is a little more subdued. The beer has a clean lactic acid sourness, and a slightly doughy malt character at a low level.
  • Mouthfeel
    • Light body, medium-high carbonation, slightly dry finish.
  • Would I Brew This Again?
    • WOW! The keg version is simply amazing, and the blend of fruit is close to perfection. I might notch back the lime just a touch (perhaps half the amount I used) so that it’s not quite as noticeable and more in a supporting role. The TrueFruit was an excellent addition, in particular helping the passionfruit to shine. This might be one of the most fun (and most enjoyable) brewing projects I’ve had in awhile.
    • Compared to the bottled version, the fruit quality is “better” on this one. Everything else is (as expected) fairly similar.
  • Overall
    • 9.5/10

Gondwana IPA

Posted on by

Chasing the perfect IPA is a perpetual task. As my brewing technique has advanced, I’ve transitioned into all-grain and adjusted grain bills, adjusted water chemistry, played with different hopping regimes, and implemented closed transfer into a keg. The results have, in the best batches, been quite satisfying–especially for “traditonal” C-hop IPAs and classic North American IPAs. I’ve also improved overall beer quality. Yet, I’m always looking to try something just a little different.

Hop derivative products are nothing new, including CO2 extracts, various bittering products, flavorings, and concentrated pellets (e.g., Cryo) released over the years. I keep an eye on what’s out there for homebrewers, and although I’ve dabbled with some concentrated hop pellets like Cryo, they’ve never been so knock-my-socks-off that I’ve gone exclusively to them. More recent products like Abstrax are intriguing, but just odd enough (and expensive enough) that I haven’t jumped at them. But, I’ve been reading more about all of these lately, so I thought I would give them a try. I’m also wanting to get the super crisp, super fruity profile that the best beers with Southern hemisphere hops can have. Time to experiment!

I built my current recipe exclusively around Southern hops, from Australia and New Zealand. I wanted something with big tropical fruit notes and a bit of citrus (but not straight citrus, like some North American IPAs). I chose a combo of Galaxy and Moutere to hit that for the boil and whirlpool. To amp things up, but avoid the astringency of too many hops, I implemented Cryo Riwaka, for the passionfruit and citrus notes in the dry hop. Finally, I rounded things out with a dose of Abstrax Omni Hop Profile, targeting a Galaxy-type expression. In order to let the hops shine through, I followed my all-grain, low mash temperature malt bill from recent “modern” IPA attempts. I also turned down the bitterness, from around 67 IBU in my most recent IPA to 50 IBU here. Although I don’t with US-05 as much as I used to, the peachy quality that it provides seemed like a nice way to augment the overall fruity qualities I wanted in this beer. I had a lot of fun conceptualizing the recipe in this batch, and choosing the ingredients to hit my overall concept.

Note that this is my second recipe with the name of “Gondwana IPA.” My first was over a decade ago, during only my second all-grain brew session. The name is too good to leave to an early effort, so I’m going to repurpose it for a new generation of brewing.

Gondwana IPA

  • 9.5 lb. 2-row pale malt (Rahr)
  • 3 lb. Synergy Select pilsen malt (Briess)
  • 1 lb. Vienna malt (Weyermann)
  • 0.5 tsp. BrewTanB, added to mash
  • 1 oz. Moutere hop pellets (15.7% alpha), 20 minute boil
  • 0.5 tsp. BrewTanB, 10 minute boil
  • 1 Kick Carrageenan tablet, 5 minute boil
  • 1 oz. Galaxy hop pellets (16.9% alpha), 15 minute whirlpool at 185°
  • 1 oz. Moutere hop pellets (15.7% alpha), 15 minute whirlpool at 185°
  • 1 pkg. Safale American ale yeast (US-05)
  • 1 oz. Cryo Riwaka hops (12.4% alpha), dry hop in keg
  • 2.5 mL Southern Hemisphere (AU) Tropical Omni Hop Profile, Abstrax, added to keg
  • 1 oz. Biofine Clear, added to keg

Target Parameters

  • 75 minute infusion mash, 148°, full volume mash
  • 1.062 o.g., 1.010 f.g., 6.8% abv, 50 IBU, 4 SRM
  • Water built from RO, to hit 94 ppm Ca, 156 ppm SO4, and 51 ppm Cl.
  • 5.25 gallon batch

Procedure

  • I built the water up from scratch, with 7.5 gallons of RO water, 8 g gypsum, and 3 g calcium chloride, to hit my brewing water profile.
  • After heating the water to 154°, I added the grains as well as 18.6 mL of 10% phosphoric acid to adjust mash chemistry.
  • I held the mash at `148° for 75 minutes, with recirculation, before pulling the grains and heating to a boil.
  • In total, I collected 6.6 gallons of runnings with a gravity of 1.053, for 68% mash efficiency.
  • Once the kettle was at a boil, I added the hops and finings per the recipe. I boiled for 60 minutes.
  • After the full 60 minute boil, I chilled the wort to 185° and added the whirlpool hops, and recirculated. I had a realization, that I could use my Anvil heating element to keep the whirlpool at the temperature! It’s somewhat silly that it took me so long to realize this (temperature drops due to the recirculation, so start whirlpool temp is higher than end whirlpool temp otherwise)…but now I can incorporate that into my process for more consistent results!
  • After the 15 minute whirlpool, I continued chilling down to 72°, transferred to the fermenter, pitched the yeast, and continued chilling in the fermentation chamber down to 66°.
  • I brewed this beer on 15 March 2026. Starting gravity was 1.060.
  • Fermentation temperature was held at 66°.
  • A very light krausen was visible on the surface of the beer by 16 March 2026, and a solid krausen was visible by 17 March 2026. I noted there wasn’t a lot of bubbling in the airlock, so I wonder if there’s not a small leak somewhere in the way the lid gasket is seated.
  • I started the cold crash for the beer on 15 March 2026, and kegged the beer on 1 April 2026, using a closed transfer.
  • I added the Cryo hops in a large bag after the transfer was completed, doing as quick of an addition as I could. I ran the CO2 into the keg at very low pressure while doing so, to keep a blanket of CO2 in place and hopefully minimize oxygen ingress.
  • Final gravity was 1.007; down from 1.060, this works out to 7.0% abv.
  • I dry hopped at ~34°, while carbonating.
  • I tried to remove the dry hops on 4 April 2026, but they had sunk in the keg, so I couldn’t retrieve them. Ah well!
  • On 4 April 2026, I added 2.5 mL (0.5 tsp.) of the Abstrax product.

Tasting

  • Appearance
    • Light gold in color, with a light shimmery haze–it’s not a “hazy” in the sense of being opaque or murky, just a beer with a hop/chill haze. The beer has a nice white head with good retention and a bit of lacing on the glass.
  • Aroma
    • A nice bouquet of tropical fruit, at a moderately high intensity. I perceive it as sweet orange, passionfruit, and mango.
  • Flavor
    • Medium high bitterness, with a flavorful hop quality–sweet pineapple, orange, a fair bit of white peach; overall, a sweet and fruity flavor from the hops. Clean fermentation, with a slight peach ring candy flavor at times. The maltiness is light and has a slightly grainy quality.
  • Mouthfeel
    • Medium light body, moderate carbonation, dry finish.
  • Would I Brew This Again?
    • This is a good IPA–I think I threaded the flavor/bitterness needle pretty well. It avoids astringency, and has a perfect level of bitterness and hop flavor for what the beer is. The sweet hop sensation is a new one for my home brews, and very cool to experience. The haze marks the beer down slightly, but that’s more cosmetic than anything. I think the Abstrax adds something, but it’s nice and subtle, without being in your face. I get the sense that in my use case it’s a support alongside the other hops rather than a “whammo” in your face experience. I like that my hopping regimen avoids the diesel flavor I got in a commercial IPA with Riwaka that I recently sampled. The “lower” bitterness (50 IBU calculated, versus 60 or 70 as in my typical batches) lets the hop flavors shine over the bitterness. In all, I think this is a successful experiment and use of a variety of non-convention (i.e., non-T90) hop products!

Rated “PG” (for Pineapple Guava) 2026

Posted on by

Our feijoa (pineapple guava) tree had a slack year in 2024-2025 (probably due to dry conditions), so I wasn’t able to gather any fruit. But, the tree produced fairly well towards the end of 2025, so it was the perfect time for a rebrew of my old favorite sour beer. The feijoa fruits weren’t quite as large this year, and were perhaps a bit riper when I picked them, so the overall quality is different from the first batch. That said, it still turned out as a great beer (even if a bit of extra work)!

Everything is pretty much the same this year as the previous version; there is a mix of pilsner malts, because I was getting to the end of my Pilsner Zero supply. With a smaller harvest of fruit, I opted for a 2.5 gallon instead of a 3 gallon recipe.

Rated “PG” (for Pineapple Guava) 2026

  • 1 lb. 12 oz red wheat malt (Briess)
  • 14 oz. Pilsner Zero malt (Viking)
  • 8 oz. Synergy Select Pilsen Malt (Briess)
  • 2 oz. rice hulls (added to mash)
  • 0.25 tsp. BrewTanB, added to mash
  • 0.25 tsp. BrewTanB, 10 minute boil
  • 1 oz. Saaz whole hops (South Dakota; est. 3.5% alpha), 5 minute boil
  • 0.5 tsp. yeast nutrient (WLN1000), 5 minute boil
  • 1 pkg. Wildbrew Philly Sour (Lallemand)
  • 2 lb. feijoa (pineapple guava) puree, added at end of fermentation

Target Parameters

  • 60 minute infusion mash, 152°, full volume mash
  • 1.031 o.g., 1.006 f.g., 3.2% abv, 5 IBU, 3 SRM
  • Claremont tap water, neutralized, to hit 120 ppm Ca, 7 ppm Mg, 89 ppm Na, 50 ppm SO4, 120 ppm Cl, 10 ppm bicarbonate, -81 RA
  • 2.5 gallon batch

Procedure

  • Starting with 3.75 gallons of tap water, I added a quarter of a Campden tablet to drop the chloramines, and then 2.65 mL of 88% lactic acid, to neutralize the bicarbonates.
  • I heated the water to 155°, before adding the grains, and holding at 152° for 60 minutes, with recirculation.
  • After the main mash, I raised the mash temperature to 168° and held it there for 10 minutes.
  • Once the mash was done, I pulled the grains. I had 3.4 gallons of runnings with a gravity of 1.025, for 72% mash efficiency.
  • I brought the runnings to a boil, and boiled for 60 minutes, adding hops and other ingredients per the recipe.
  • After the 60 minute boil, I chilled to 84°, transferred to the fermenter, pitched the yeast, and fermented at ambient. I wrapped a towel around the temperature to maintain temperature.
  • I brewed the beer on 18 February 2026; starting gravity was 1.033.
  • The beer was down to 70° by the morning of 19 February 2026, with active bubbling in the airlock. I put my fermentation heater next to the fermenter and wrapped the fermenter in a towel in order to keep the temperature up.
  • The fermenter was around 76° when I checked it on 22 February 2026.
  • I added the fruit puree on 22 February 2026. I had picked the feijoa at the end of December, skinned it, and then froze the pulp. After thawing, I pureed the pulp with an immersion blender, heated the puree it to between 160° and 165°, and then let it sit for 30 seconds. I added the pasteurized puree to the fermenter at this point, which raised the temperature to 86°. There was a gentle krausen on top when I opened the fermenter.
  • The fermenter sat at ambient, until I kegged the beer on 7 March 2026. I used 1.5 oz of corn sugar dissolved in water to start carbonation (and reduce oxygen).
  • Final gravity was 1.009, down from 1.033; this works out to 3.1% abv, pretty close to my initially estimated target.
  • After a few weeks, I moved the keg to the fermentation chamber and topped up the CO2 with forced carbonation.

Tasting

  • Appearance
    • Very hazy and straw-colored beer, with a surprisingly persistent white head (likely helped by the high level of carbonation).
  • Aroma
    • Highly tart, acidic aroma, with a medium level of tropical fruit; very ripe, almost like papaya, especially on the initial pour; as the beer warms, I pick up more guava, and a bit of apricot and pineapple.
  • Flavor
    • Very clean sour profile, with a lactic acid character; a light bread dough malt flavor. As the beer warms, a medium-low level of tropical fruit comes through, with well ripened pineapple as the dominant flavor. Minimal bitterness.
  • Mouthfeel
    • Highly carbonated, crisp, light-bodied beer; a wonderful effervescent character.
  • Would I Brew This Again?
    • This is a super amazing beer, made even more special by the fact that I picked the fruit in my yard. It is just about the perfect fruited sour; the aroma is a little more “ripe” than the previous version. The flavor is not as fruit-forward (hence the 9/10), but still nice. The Philly Sour strain works well for these kinds of beers; I’m definitely sold on it! Comparing with the previous version, the color is a little lighter; maybe that’s something about the fruit?
  • Overall
    • 9/10
