Raspberry Belgian 2021

Posted on by

According to my records, this is the fifth time I’ve made Raspberry Belgian. It is one of my favorite recipes, without a doubt. The process is a fair bit of work, and it’s not the cheapest thing to brew, but WOW, are the results worth it!

My approach to this has morphed considerably over the years, and there are inevitably some variations in ingredients and process. So, every time is different, even if they’re all more or less in the same flavor space.

As before, the key to this recipe is using fresh/frozen raspberries. Tons and tons of raspberries–4.5 pounds, to be precise. I used just frozen ones this time, which I thawed and pureed before adding to the fermenter. Canned purees just don’t “pop” in the same way. For souring, I tried out the Lactobacillus Blend from Omega Labs, which is what the local shop had on-hand. Past versions of the recipe used acidulated malt in the grist, which was a hold-over from the original “bacteria-free” version, and I decided to just ditch that because it was unnecessary.

Raspberry Belgian 2021

  • 6.5 lb. Viking Pilsner Zero Malt
  • 2.5 lb. white wheat malt (Great Western)
  • 1 lb. flaked wheat
  • 0.5 lb. Carapils malt (Briess)
  • 0.5 lb. rice hulls
  • 0.5 oz. Magnum hop pellets (10.1% alpha), 60 minute boil
  • 1 tsp. WLN1000 yeast nutrient (White Labs), 10 minute boil
  • 1 pkg. Belgian Wit Ale Yeast (WLP400), prepared in 1L vitality starter
  • 1 pkg. Lactobacillus Blend (Omega Labs OYL-605)
  • 72 oz. frozen raspberries, pureed

Target Parameters

  • 1.048 o.g., 1.012 f.g., 18 IBU, 4 SRM, 4.8% abv
  • 154° full-volume mash, 60 minutes
  • Overnight kettle sour
  • Claremont tap water, no adjustment

Procedure

  • Way back in May, I made a starter for Pannotia White IPA using WLP400, but it was suuuuper slow to kick off. Worrying that it was dead, I got some Whiteout (Imperial Yeast), but kept the WLP400 starter going just in case. After a day or two, it was off to the races, and so I harvested the results to save for a later brew–which turned out to be the raspberry brew!
  • I mashed in with 7.25 gallons of water at 160°, and held the mash at 154° for 60 minutes with recirculation. I added 7 mL of 88% lactic acid to adjust the mash pH. I raised the temperature to 168° for a 10 minute mash-out, and then removed the grain basket.
  • In total, I collected 6.25 gallons of runnings with a gravity of 1.038, for 61% mash efficiency. This is a bit low, but that seems to be the case for these adjunct-heavy beers (and my mill seems to be not quite tight enough, after inspection of equipment).
  • Next, I boiled the runnings for 5 minutes, before chilling down to 95°. I added 25 mL of 88% lactic acid, to get the pH down to 4.4, and then added the lacto culture. Because I’m using the Foundry, I just let the runnings in the kettle, and set it to maintain temperature at 90°. I did this step on 14 August 2021.
  • After 25 hours, the pH was down to 3.5, right in my target range. I called this perfect!
  • While getting the soured runnings ready, I made a SNS (shaken-not-stirred) starter for the harvested yeast culture.
  • I boiled the runnings, adding hops and yeast nutrients per the recipe. After 60 minutes, I chilled the wort, transferred to the fermenter, and then chilled down to 66° before pitching the yeast starter.
  • I started primary fermentation on 15 August 2021, holding at 66°.
  • On 19 August 2021, I added 72 oz. of pureed frozen raspberries, and raised the temperature to 68°.
  • On 22 August 2021, I brought the beer out to ambient, around 75° or so, to finish up.
  • I kegged the beer on 28 August 2021. At this point, it had a final gravity of 1.013, which works out to 4.0% abv. With the extra sugars from the fruit, actual abv might be a touch higher.

Tasting

  • Appearance
    • The beer is gorgeous! I pours with a pink, frothy, and somewhat persistent head. The beer itself is dark pink, and moderately (but not overly) hazy. I think it’s looking clearer than might be usual, because I’m using a floating dip tube. I wouldn’t mind a little extra haze, if it helped augment the mouthfeel and flavor.
  • Aroma
    • Raspberry is prominent, with a bit of tartness also.
  • Flavor
    • The beer is moderately sour, but not over the top. The sour character is clean (one person who tasted it described it as a sour patch kid–that’s a high compliment in my book!). Bitterness is perceived as low. The raspberry comes through very nicely. There might be a slight wheat flavor, but in general I don’t think the malt is terribly perceptible. I’m a bit surprised that the Belgian yeast character doesn’t come through more, either.
  • Mouthfeel
    • This beer has a light body and effervescent quality, with a tart, modestly sour, and dry finish.
  • Would I Brew This Again?
    • This is a wonderful beer! It’s incredibly drinkable, especially during warm weather. I wouldn’t mind a touch more malt character and a little bit more prominent Belgian yeast character…I would be curious to see if it’s genuinely no Belgian character, or if that is just being covered up by the raspberries. Perhaps I’ll try fermenting at a higher temperature next time, to bring out the phenols more prominently. Those are truly minor issues, and really just in the category of optional tweaks to consider.

Raspberry Belgian 2020

Posted on by

I’ve brewed this beer at least three or four times, and I keep coming back to it as one of my very favorite recipes. It’s crisp, it’s low alcohol, it’s flavorful, and it’s well out of my usual brewing styles. I wouldn’t want this year-round, but it sure is a nice treat every once in awhile!

My personal take on this recipe–which started out as a clone of Funkwerks Raspberry Provincial–has evolved since I first brewed it in 2017. Every batch is a bit different, especially in the souring strain and the type of raspberry puree added. It never fails to be a great beer.

Raspberry Belgian 2020

  • 4.75 lb. pilsner malt (Weyermann)
  • 2.5 lb. pale wheat malt (Weyermann)
  • 1.75 lb. acidulated malt (BestMalz)
  • 0.5 lb. Carapils malt
  • 0.5 lb. flaked oats
  • 0.5 lb. flaked wheat
  • 6 oz. rice hulls
  • 0.35 oz. Magnum hop pellets (13.2% alpha), 60 minute boil
  • 0.5 pkg. (~5 g) of Wildbrew Sour Pitch (Lallemand)
  • 1 pkg. Whiteout Belgian Wit Yeast (Imperial #B44)
  • 36 oz. raspberry puree

Target Parameters

  • 1.048 o.g., 1.013 f.g., 15 IBU, 3 SRM, 4.5% abv
  • 155° full-volume mash, 60 minutes
  • Overnight kettle sour
  • Claremont tap water, no adjustment

Procedure

  • I mashed in with ~8.5 gallons of water at 160°, to hit a 155° mash temperature target. After 60 minutes, I vorlaufed and collected the full volume of runnings.
  • In total, I collected 6.7 gallons of runnings with a gravity of 1.033. This was way below my target (and only 57% mash efficiency), so I added 0.75 lb. of extra light DME to bring the gravity up to 1.038.
  • I boiled the runnings for 10 minutes and then chilled to 115°. I added 1 tbs. of 88% lactic acid, to bring the pH down to ~4.4.
  • Once the kettle temp was down to 105°, I added 5 g of the Wildbrew Sour Pitch, stirred gently, and left it on a heating pad in a warm garage.
  • I started the souring process at around 10:30 am on 18 July 2020, and it was down to ~3.35 by the next morning. The sour level was right where I wanted it, when I sampled a little.
  • I boiled the beer for an hour, adding hops per the schedule as well as some yeast nutrient.
  • I chilled the wort and put it into my fermenter, bringing the temperature down the rest of the way in my fermentation chamber. I pitched the yeast, and let it ferment at 66°. The starting gravity was 1.046.
  • I pitched the yeast on 19 July 2020, and added fruit puree on 23 July 2020.
    • To make the puree, I took frozen raspberries (purchased fresh a few weeks prior, sorted, and frozen) and thawed them out. I had 72 ounces by mass, which was around 130 ounces by volume of whole raspberries. 12 ounces by weight should make around 6 ounces of puree by volume, so I ended up with around 36 ounces (a quart) of puree. To make the puree, I heated the raspberries in a double boiler, mashing them up. I heated the mixture to between 150° and 170°, with the bowl sitting in near-boiling water. I let it sit for 15 minutes and then chilled in an ice bath, before adding the puree to the fermenter.
  • I kegged the beer on 1 August 2020. Final gravity at that time was 1.020, for 3.3% abv; I wonder if the yeast hadn’t completely fermented out? I usually agitate the fermenter when I’m using the various Belgian wit strains, because they do tend to stall out without babysitting. Oh well…I figure that any final fermentation will hopefully wrap up in the keg.
  • I added 3.2 oz. of corn sugar boiled for ~2 minutes in 1 cup of water, and then sealed up the keg (adding a touch of pressure to make sure the lid was seated).
  • Carbonation level maxed out at around 24 psi at 72°, which is not terribly great as a level of carbonation for this style. That’s only 2.2 or so volumes of CO2, and I was aiming for 3.0 at least. I used my CO2 talk to top things up.
  • On 9 August 2020 (the same day as the tasting), I decarbonated a sample and measured gravity with both hydrometer and refractometer, getting a final gravity of 1.017. This works out to ~3.8% abv, and if I were to guess, around 4% abv when you factor in the sugars from the raspberry.

Tasting

  • Appearance
    • Right now (second day on tap for the keg), this beer has a gorgeous deep pink color, with a prominent haze. It pours with a frothy white head that subsides to a relatively continuous thin blanket.
  • Aroma
    • This beer smells like fresh raspberry. I get maybe a little bit of the citrusy Belgian wit yeast character behind that, but the raspberry is front and center here.
  • Flavor
    • What else? Raspberry! More seriously, the beer has a pleasant (but not over-the-top) tartness, with a berry and citrus character. The malt is pretty subdued, and largely overwhelmed by the fruit and sour notes. But, raspberry definitely dominates.
  • Mouthfeel
    • Crisp and light bodied, with a nice smooth finish. Carbonation is high, which gives a pleasant and spritzy character to the beer, but the heavy amount of suspended yeast and the malt bill keep it from being too thin.
  • Would I brew this again?
    • This is one of my very favorite summer beer recipes. It has evolved considerably from the original clone recipe, and it has further evolved from my initial few attempts. It’s such an interesting beer, and is a good reward for the above-average amount of effort and above-average ingredient cost. The only minor change I might make would be to ditch the acidulated malt–it’s a holdover from the original recipe, which used this malt alone to get the desired sour character.

The Ones That Got Away…

Posted on by

For a variety of reasons, I haven’t been able to blog about every single batch I brewed in 2018. Many of the ones that didn’t make the cut were repeat brewings of successful recipes. Because I’m not likely to get all of them with full blog posts at this stage, I’m giving myself semi-amnesty by listing them with brief comments.

  • Cerveza de Jamaica 1.1
    • This was a rebrew of the first version, which I really liked. Version 1.1 was modified very slightly to add a little more hibiscus and a little more orange peel, and the result was an incredibly tasty beer!
  • Double IPA / Hoppy Blonde Ale
    • This was an experiment with parti-gyle techniques, co-brewed with a friend. The double IPA ended up at around 7.8% abv, and was fairly tasty. The blonde ale rounded out at 4.6% abv, and was also pretty nice. The experiment was a lot of work on brew day, but a fun attempt.
  • Raspberry Belgian 2018
    • I rebrewed a house favorite recipe for a beer festival, and thus didn’t really get to taste the final result (sadly). Everything on the process was tasty, though, so I’ll be doing this one again too.
  • Bavarica Session IPA
    • This one was pretty disastrous! The flavors clashed horribly (never again will I use Munich malt in a session IPA), and I dumped most of the batch.
  • Grab Bag IPA
    • Basically to use up a bunch of ingredients. Nothing memorable here, although it was pretty drinkable.
  • Grapefruit Wheat Ale
    • I don’t have many notes on this, other than that I used Amoretti grapefruit craft puree for some of the flavoring.

Kegging Updates: Raspberry Belgian, Thumbspike Saison 2.1

Posted on by

I’ve done a decent bit of kegging this past week, to square away some beers slated for the Lake Arrowhead Brewfest that I’ll be serving with Horse Thief Brewers. The festival is just under a month away, but with a new baby soon to arrive in the household I know that time will be tight. Gotta keg while the kegging’s good!

My cold storage space is also tight, so I’ve decided to get the beers carbonated and conditioned using a more “traditional” keg priming technique. Not only does it cut down on my CO2 usage, but it also should help to eat up any residual oxygen from the transfer and help the beers stay a bit fresher. Now of course it would be ideal to do the full keg purge with CO2 and closed transfer thing. But as I said…I’m tight for time and not keen on always blowing through my CO2 supply. I also feel that these two beers should hold up pretty well (both are fairly high alcohol and one is quite tart); if it was a delicate lager, crystal malt heavy porter, or hoppy IPA, I would definitely do things differently.

In any case, here are the details on everything.

Thumbspike Saison 2.1

I brewed this beer on June 25, and fermented it at the ambient temperature–around 75° on up. I kegged the batch on 12 July 2017, with 2.75 oz. of corn sugar boiled in 1 cup of water. Around 5 gallons went into the keg. Final gravity was 1.003, down from 1.055. This works out to around 6.8% abv.

Raspberry Belgian 1.1

I brewed this beer on 27 June, fermenting it at around 66°. On the fourth day of fermentation, 1 July 2017, I added around 1L (~4.25 cups) of Vintner’s Harvest raspberry puree. After about a week, I moved it out of the fermentation chamber to finish out at ambient temperature, around 78°.

I kegged the beer on 14 July 2017. The flavor was nice and tart, although at this point the raspberry comes through more in the aroma than in the flavor. I will have to see if that changes when I chill it and serve it carbonated; there might be some minor adjustments required prior to the festival, if that’s the case.

Because I wanted to keep this beer for home use too, I split it between two mini-kegs. Three gallons went into one, with 1.82 ounces of corn sugar boiled in 1 cup water (targeting around 3 volumes of CO2). The remaining 2 gallons or so went into another keg, which I force carbonated to around 2.8 volumes.

Final gravity for this batch was 1.013, down from 1.044. That clocks in at 4.1% abv–a very nice session beer!

In another brew for the Lake Arrowhead Event, I’m doing a second attempt at my Raspberry Belgian. The first version turned out reasonably well, although I felt like it needed a bit more tartness as well as a bit more body. I thought the body could be augmented by doing a batch sparge instead of a no-sparge technique; the latter consistently leads to low efficiency on my system and thus a lower starting gravity. As for the tartness…I elected to do a kettle sour instead of improvising with acid malt.

Recently, one of my fellow homebrew club members presented on kettle souring, particularly his approach with using a yogurt-based culture. Now, I’ve done kettle souring once before–with incredible results–but in that case I used a commercial lacto strain specifically for homebrewers. I was intrigued by the thought of souring more cheaply, and thought this was a great batch in which to give it a try.

Sour culture ingredients and tools

For my culture, I chose The Greek Gods’ brand nonfat Greek yogurt–other homebrewers have reported success with it, and it has a nice blend of various lacto strains. So, 24 hours before my planned brew session, I made a 1L starter (1 L water, 100 g extra light DME, and a pinch of Fermax yeast nutrient) with 3 tsp. of yogurt. Because I’m not using a stir plate, next time I’ll want to break up the yogurt a bit; I noted that the first clump I put in never really broke up well, even with some gentle swirling. Greek yogurt is thick! I let the starter sit overnight on a heating pad set for 100° (I taped the sensor on the side of the flask). By the next day, it had a nice sour aroma, so I deemed it ready to go.

Raspberry Belgian 1.1

  • 5 lbs. Château Pilsen malt (Castle Malting)
  • 2 lbs. white wheat malt (Great Western Malting)
  • 0.5 lb. carapils (Briess)
  • 0.5 lb. flaked oats (store brand quick oats)
  • 0.5 lb. flaked wheat
  • 0.20 oz. Warrior hop pellets (15.8%), 60 minute boil
  • 0.15 oz. Willamette hop pellets (4.9%), 15 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 0.5 tsp. Fermax, 10 minute boil (added before souring)
  • 1 tsp. Fermax, 10 minute boil (added after souring)
  • 1 pkg. Belgian Wit Ale yeast (WLP400), prepared in 1L starter
  • 4.25 cups (1 L) raspberry puree (Vintner’s Harvest brand)

Target Parameters

  • 156° mash, 60 minutes
  • 10 minute boil and 24 hour kettle sour prior to 60 minute boil
  • 1.044 o.g., 1.012 f.g., 4.2% abv, 14 IBU, 3 SRM, 5 gallons into the fermenter

Procedure

  • I prepared the sour culture as specified above, 24 hours in advance.
  • On brew day (part I), I mashed in with 3 gallons of water at 166.5°, to hit my mash target temperature of 156° right on the nose!
  • I added 1.6 gallons of water to sparge, vorlaufed, collected first runnings, and then added 3.5 gallons of water for the second sparge.
  • In total, I collected 6.75 gallons of wort at a gravity of 1.038–81% efficiency!
  • Using 3.5 tsp. of 88% lactic acid, I adjusted the pH of the wort to around 4.2. This was a slight overshoot of my target, but I figured I would be OK.
  • I boiled the wort for 10 minutes, adding the first bit of Fermax. After 10 minutes, I chilled the wort to ~100° and then added the yogurt culture. I left the kettle on a heating pad, with the temperature controller set to 100°.
  • After ~21 hours, the temperature had settled to around 94°, and the pH was down to ~3.1 (a bit too sour for my tastes!). I added 1.5 tsp. of chalk to the kettle to raise things up a bit.
  • I boiled the wort for 60 minutes, adding the various ingredients per the schedule in the recipe. At the end, I chilled the wort down to 80° and then transferred it into my fermenter. Six gallons of wort made it in. I then did the remaining chill to 66° in my fermentation chamber. I pitched the yeast, and let things move along.
  • The final pH prior to the yeast pitching was 3.39; much more reasonable. It may even be a bit too tart yet, but we’ll see. Starting gravity was 1.044, right where I wanted it to be!
  • I brewed the beer and pitched the yeast on 27 June 2017. Initial fermentation was at 66°. After 4 days, on 1 July 2017, I added 4.25 cups of raspberry puree and raising the temperature to 68°.
