Alta California Lager

It’s late spring in California…theoretically, this should be a warm time of the year. A few months back, I wanted to have a clear, clean, tasty Mexican-style lager on hand for the anticipated afternoons out on the patio. It’s ended up being a cooler and rainier stretch than I expected, but that hasn’t hampered my enjoyment of this beer.

I’ve never brewed a Mexican-style lager in the vein of Corona or Modelo before, so this challenge started with some research. Corn is a key ingredient–but when I stopped by my local shop, they had just sold out of their last flaked corn (everyone else had the same recipe plans, I guess)! So, I took the suggestion to try a cereal mash with corn grits. This contingency plan apparently made all of the difference.

My recipe is based primarily on the Light Mexican Lager recipe in the May/June 2017 issue of Zymurgy (by Amahl Turczyn). The name for this recipe is an homage to the old provincial name for my part of California. It has little link with anything historical, because Alta California ceased to exist before German brewing techniques were widely adopted in Mexico…

This beer is going down as a legendary batch–I had fun brewing it with my dad (we rarely get to brew together because of the distance), and the beer tastes amazing. The cereal mash was a ton of work and substantially lengthened my brew day, but the results were worth it.

White corn grits, ready to go into the cereal mash

Alta California Lager

  • 5.5 lbs. Barke pilsner malt (Weyermann)
  • 2 lbs. white corn grits
  • 1.5 lb. Vienna malt (Great Western)
  • 4 oz. rice hulls
  • 0.35 oz. Magnum hop pellets (13.2% alpha), 60 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 tsp. Fermax, 10 minute boil
  • 1 oz. Saaz hop pellets (3.5% alpha), 5 minute boil
  • 1 pkg. WLP940 Mexican Lager yeast (White Labs), prepared in 1.75 L starter

Target Parameters

  • 60 minute infusion mash with cereal mash, 152°, batch sparge
  • 1.055 o.g., 1.012 f.g., 5.7% abv, 44 IBU, 8 SRM
  • “Mexican lager water”, built from ~8.5 gallons of RO water with 1.5 g of calcium chloride, to hit ~13 ppm Ca and 23 ppm Cl, -9 RA

Procedure

  • This was a complicated brew session! Lots of moving parts, all happening at roughly the same time.
  • A few days in advance, I made a 1.75L starter, letting it ferment out and then cold-crashing. The supernate was decanted off before pitching.
  • My cereal mash procedure followed recommendations from Milk The Funk. I combined 0.5 lb. of the pilsner malt with the 2 lb. of white corn grits, adding water until things were at the right consistency. This was around a gallon of RO water. I added water until the grains approximated a “thin gruel” consistency, and held it at 158° for 5 minutes. Then, I heated the cereal mash to a boil, stirring constantly for 30 minutes. We added water as needed to keep it from getting too thick.
  • As the cereal mash was nearing its end, we started the main mash, using 3 gallons of RO water with ~0.5 g of CaCl, heated to 138°. We hit a mash temperature (for just the barley, exclusive of the barley and corn in the cereal mash) of 133°. I added 6 mL of 88% lactic acid, and then added in the near-boiling cereal mash. This brought the temperature up to 145°. I added another 0.5 gallon of water at near boiling to hit around 148.5°.
  • After 75 minutes, the mash was down to 143°. I added 1 gallon of water at 200° to bring the mash up to 149°. I let this sit for 15 more minutes, and then used an iodine test to check for conversion. Success! The mash was converted completely.
  • I collected the first runnings, and then added 4.5 gallons of RO water with 1 g of CaCl, to raise the mash up to 160°. After 10 minutes, I vorlaufed and collected the second runnings.
  • In total, we collected 7.1 gallons of runnings, with a gravity of 1.037. This equates to 79% mash efficiency!
  • Because my gravity was a little low and my volume a little high, I boiled the runnings for 20 minutes before adding the hops. This was followed by a 60 minute boil, adding the various ingredients per the recipe. Towards the end of the boil, the gravity was up to 1.048, a little higher than I wanted. So, I added 0.25 gallon of RO water for adjustment.
  • After the full 80 minutes of boiling, I chilled the wort down to ~80° and transferred to the fermenter. I chilled it down further to 50° before oxygenating (30 seconds) and pitching the yeast.
  • I brewed this beer on 2 April 2019, starting with a 50° fermentation temperature as mentioned above. On 3 April, I raised the temperature to 53°. On 9 April, I raised the temperature to 60°, because I wanted to kick this through quickly.
  • I raised the temperature to 62° on 12 April, and 67° on 14 April.
  • Final gravity was 1.010, which equates to 4.6% abv. I cold crashed to 33° on 16 April 2019.
  • I kegged the beer using a closed transfer on 24 April 2019. This was done to reduce oxygen pick-up and keep the beer fresher for longer.
  • I force-carbonated the beer,noted that it had dropped pretty clear within about 2 weeks, and crystal clear within about 3 weeks. By the time of my tasting (~4 weeks after kegging), this beer was brilliant!

Tasting

  • Aroma
    • Clean, slight hint of corn, a little bit of hop spiciness
  • Appearance
    • Brilliantly clear, light gold in color. The tall white head settles down to a rim around the glass as the beer is consumed
  • Flavor
    • Crisp and clean; the grainy malt has a hint of corn behind it, and that is backed up by an assertive but not overwhelming hop bitterness. The finish is tilted towards the bitter end versus the malty end, but not overly so.
  • Mouthfeel
    • Off-dry, moderately high carbonation, smooth finish
  • Would I brew this again?
    • This is (modestly speaking) an amazing beer! I’m incredibly impressed by how this one rounded out. It’s eminently drinkable, and ridiculously beautiful in appearance. When I brought it to my brew club meeting, several people thought that I had thrown a commercial ringer into the mix! I’ve never had a lager clear so completely and so quickly. I suspect it’s a combination of the yeast strain and cereal mash–next time I brew this recipe, I won’t be making any changes or taking any shortcuts!

    • 10/10

GBP70 – Bohemian Pilsner Recipe & Tasting

In honor of my dad’s 70th birthday (he introduced me to homebrewing, after all!), I brewed a Bohemian-style pilsner. It was pretty tasty, and sadly didn’t last long enough even for me to do a formal tasting. I made the mistake of serving it at a party, and the keg was finished before I could blink!

GBP70 (Greg’s Birthday Pilsner 70)

  • 10.5 lbs. Barke pilsner malt (Weyermann)
  • 2.3 oz. melanoidin malt (Weyermann)
  • 0.3 oz. Carafa Special III malt (Weyermann)
  • 2 oz. Saaz hop pellets (3.0% alpha), 60 minute boil
  • 0.75 oz. Saaz hop pellets (3.5% alpha), 60 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 tsp. Fermax yeast nutrient, 10 minute boil
  • 2.25 oz. Saaz hop pellets (3.5% alpha), 5 minute boil
  • 2 pkg. W34/70 Saflager Lager Yeast (Fermentis)

Target Parameters

  • 60 minute infusion mash, 150°, no sparge
  • 1.049 o.g., 1.010 f.g., 5.2% abv, 38 IBU, 5 SRM
  • Water built from RO to hit targets of 7 ppm Ca, 2 ppm Mg, 2 ppm Na, 5 ppm SO4, 5 ppm Cl, 15 ppm HCO3

Procedure

  • To 7.75 gallons of RO water, I added 0.6 g baking soda, 0.4 g CaCl, and 0.3 g gypsum.
  • I heated the mash water to ~160°, added to the mash tun, allowed to cool to 155.4°, and then added the grains along with 10 mL of 88% lactic acid.
  • I hit 150.7° on the mash temperature–not too bad! It was down to 148.7° after 45 minutes.
  • After 60 minutes, I collected 6.5 gallons of wort with a gravity of 1.041. This works out to 67% efficiency. That’s a fair bit lower than my typical efficiency (73 to 75%), but not unexpected given the no-sparge methods. I added 0.25 gallons of RO water to bring up the volume in the kettle.
  • I boiled for 60 minutes, adding hops and other ingredients per the schedule.
  • I chilled the wort to 75° in the kettle, and chilled the rest of the way down to 49° after transferring to the fermenter. I oxygenated for 60 minutes at this point, and then pitched the dry yeast directly into the wort.
  • Starting gravity was 1.046 on 12 January 2019.
  • I raised the brew temperature to 64° on 26 February 2019, and cold crashed on 28 February 2019. I kegged the beer (using a closed-transfer technique, directly into the CO2-purged keg) on 9 March 2019.
  • Final gravity was 1.010, down from 1.046. This equates to 4.9% abv.

IMG_20190327_202833General Tasting Impressions

I didn’t get to do a formal tasting for this one, and it was finished before it really hit its ultimate peak, but overall I’m pretty happy with it. The malt flavor was spot-on, and I think I’ve finally iterated into a good balance of melanoidin malt within my no-decoction Bohemian pilsner recipes. The beer was pretty clear, but would have cleared to brilliant with another week or two in the keg. The head and head retention were fairly good also, but not the best I’ve ever had. Not sure why that was. I’m still chasing a perfect Saaz hop aroma in my Bohemian pilsners; it’s just a matter of finding the right hops with the right freshness. The ones I used in this batch weren’t awful, but they weren’t awfully exceptional, either. Overall, I would give this recipe 8/10, with targeted improvements to mainly chase the best possible hop flavor.

Bierstadt Pils Clone

It’s pils time again, as I continue my exploration of European lagers. The July/August 2018 issue of BYO magazine had a tasty looking clone recipe, for Bierstadt Lagerhaus’ Slow Pour Pils. Its simplicity was beautiful–pilsner malt, acidulated malt, Hallertau Mittelfrueh hops, and lager yeast. Additionally, it gave me a chance to play around with more step mashes and decoctions.

I followed the published recipe pretty closely, adjusting just slightly on my additions to ensure that the bittering hops would still hit my target of ~33 IBU. But, I then saw a correction in a later issue that the whirlpool addition should instead be a late hop addition. I figure this probably won’t mess things up too much, giving a bit more hop aroma, although also leaving slightly more potential for haze. In any case, the official recipe is posted at the BYO website.

Because I don’t have direct-fire capabilities for my mash tun, all of the steps had to be accomplished via infusions. This took a bit of creativity, but I managed reasonably well. As another wrinkle in the process, I tried for the first time a closed-transfer technique. In the past, I found that my pilsners tended to get that honey-like taste of oxidation after 6-8 weeks, which detracted from my overall enjoyments towards the end of the keg. As noted below, my attention to technique paid off pretty well!

Bierstadt Pils Clone

  • 8 lbs. Barke pilsner malt (Weyermann)
  • 0.5 lb. acidulated malt (BEST)
  • 1 oz. Hallertauer Mittelfrueh hop pellets (4.0% alpha), first wort hop and 60 minute boil
  • 1 oz. Hallertauer Mittelfrueh hop pellets (2.7% alpha), 40 minute boil
  • 1 oz. Hallertauer Mittelfrueh hop pellets (2.7% alpha), 10 minute boil
  • 1 oz. Hallertauer Mittelfrueh hop pellets (4.0% alpha), 10 minute whirlpool
  • 2 pkg. W34/70 Saflager lager yeast
  • 1 Whirlfloc tablet, 10 minute boil

Target Parameters

  • 1.048 s.g, 1.011 f.g., 4.9% abv, 33 IBU, 3.4 SRM
  • Infusion step mash with decoction
  • Water built from 8.12 gallons of RO water, with 1.6 g CaCl, 1.25 gypsum, 1 g epsom salts in 3.25 gallons of mash water, and 2.4 g CaCl, 1.9 g gypsum, 1.5 g epsom salts in 5 gallons of sparge water, to achieve -47 RA, 59 ppm Ca, 8 ppm Mg, 89 ppm SO4, 63 ppm Cl

Procedure

  • I mashed in with 2.5 gallons of water at 150° (1.054 quarts/pound of grain), aiming for a protein rest temperature of 131°. Instead, I hit 141°, and stirred frequently to get it down to 136° by the end of the 10 minute protein rest.
  • I next added 1.5 quarts of boiling water to achieve a mash rest of 144°. After 30 minutes, the temperature was down to 140°. I then added 1.5 quarts of boiling water, to hit 152°. This was below my target of 160°, so I added another 2 quarts of boiling water, to finally hit 160°. I let it sit here for 40 minutes before proceeding to the next step. In total, I added 4.5 gallons of water for the mash.
  • Next, I pulled a thin mash of 2.75 gallons, and boiled it for 10 minutes. Next, I added it back to the mash tun, to hit 168°. I let this sit for 10 minutes, vorlaufed, and collected the first runnings.
  • Next, I added 3.25 gallons of water at 180°, let it sit for 10 minutes, vorlaufed, and collected the second runnings.
  • In total, I collected 6.75 gallons of runnings with a gravity of 1.053, for 87% mash efficiency.
  • I brought the runnings to a boil, adding hops and kettle finings per the schedule. To keep bitterness closer to my calculated numbers, I removed the boil hops before adding the whirlpool charge.
  • I chilled the wort to 85°, and then transferred it to the fermenter, where it was further chilled to 49° in my fermentation chamber. I oxygenated with 60 seconds of pure O2, and then pitched the two packets of dry yeast directly.
  • Starting gravity was 1.053, with brewing on 31 August 2018. I fermented at 50°, until 25 September 2018, when I cold crashed to 36°.
  • I did a closed transfer to the keg (under CO2 pressure) on 27 October 2018.
  • Final gravity was 1.012; down from 1.053, this works out to 5.4% abv.

Little Green EuroLager

Warm weather is around the horizon, which means pale lager season is soon to be here.  Time to get brewing! This recipe is modified from the “Generic Green Bottle” formulation in Dave Carpenter’s recent Lager book. The book is a nice, accessible overview of the subject, supplementing the conversational text with a nice appendix of recipes for a variety of styles.

Relative to Dave’s recipe, I substituted in Warrior for Magnum, and used Belgian malt instead of German. Additionally, I used WLP830 instead of the suggested Wyeast 2042 Danish Lager yeast. My heart is in the right place, though–this is intended to be a clean, middle-of-the-road European lager, and I figure that the ingredient substitutions will keep the flavor in that realm.

Little Green EuroLager

  • 9.25 lbs. Château Pilsen malt (Castle Malting)
  • 0.25 lb. Carahell malt (Weyermann Malting)
  • 0.3 oz. Warrior hop pellets (15.8% alpha), 60 minute boil
  • 0.5 oz. Hallertauer Mittelfrueh hop pellets (4% alpha), 15 minute boil
  • 1 oz. Saaz hop pellets (2.7% alpha), 5 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 pkg. German Lager yeast (White Labs, WLP830)

Target Parameters

  • Infusion mash to hit target of 149°, 90 minutes, batch sparge.
  • 1.049 o.g., 1.009 f.g., 5.2% abv, 24 IBU, 3 SRM
  • Water built from RO and Claremont tap water to hit target of 40 ppm Ca, 10 ppm Mg, 9 ppm Na, 41 ppm SO4, 39 ppm Cl, 87 ppm HCO3, 37 ppm RA.

Procedure

  • Two days before brew day, I made a 2L starter. After 36 hours, I cold crashed the starter for another 24 hours.
  • I mashed in with 3.25 gallons of RO water with 2 g of Epsom salts, 2 g CaCl, and 5 mL 75% phosphoric acid, to hit a temperature of 149°. After 90 minutes, I sparged with 3.25 gallons of tap water (with 1/4 of a Campden tablet) and 1.75 gallons of RO water.
  • In total, I collected 7.1 gallons of wort at a gravity of 1.042, for 84% efficiency.
  • I boiled for 60 minutes, chilled to 75°, and then chilled to 49° over a period of 12 hours before oxygenating (a 60 second pulse) and pitching the yeast. I brewed the beer on 2 March 2018, and pitched the yeast on 3 March 2018.
  • I fermented at 52° for around 2 weeks, before raising to 66° or so. On 23 March, I dropped the temperature to 34° for a cold crash.
  • I kegged the beer on 3 April 2018, adding 1 tsp. of gelatin in 1 cup of water to clarify.
  • Starting gravity was 1.050, and final gravity was 1.006, for 5.8% abv.

Initial Impressions

My initial impressions of this beer, after it has been on tap for a few weeks, is that it is pretty awesome and almost exactly what I was looking for. Malt character is glorious, and the aroma is crisp. The yeast character is super clean. My only minor ding is that the bitterness can come across as a touch harsh; I’ve noticed that on a few batches of lighter beers where I use Warrior as the bittering hop. Despite that hop being billed as a good general bittering hop, I think it’s probably just a bit too forward for anything less robust than a porter or stout, or less hoppy than a pale ale. That aside, I’m absolutely enjoying the beer. It has received high compliments from several people whose opinions on beer I trust, which is an exceptionally gratifying piece of feedback.

First of Maibock

My homebrew club is doing an in-club style competition for its May meeting, featuring–appropriately–maibock. Flying in the BJCP guidelines as a helles bock, this is a fairly malty, higher gravity German lager. It’s also not a style I’ve brewed before–this provides a great excuse (and is a reminder of how participating in a homebrew club can push you to try new things)!

This recipe is modified in part from one that appears in Gordon Strong’s Modern Homebrew Recipes. I adjusted the grain bill and hops slightly, and opted for an infusion mash rather than a decoction mash. The main commonality is that the recipe is basically pilsner, Vienna, and Munich malt, in descending proportions. I added in some melanoidin to help up the maltiness (particularly since I wasn’t doing a decoction mash). Finally, I adjusted this to be a 3.5 gallon batch, rather than a 5 gallon batch. This is a bigger beer, and I just didn’t want 5 gallons of the stuff!

The name is mangled from a Jonathan Coulton song; apologies to everyone.

First of Maibock

  • 5 lb. Château Pilsen malt (Castle Malting)
  • 2.5 lb. Vienna malt (Great Western Malting)
  • 1.5 lb. Munich I malt (Weyermann Malting)
  • 0.25 lb. melanoidin malt (Weyermann Malting)
  • 0.45 oz. Magnum hop pellets (11.8% alpha), 60 minute boil
  • 1 oz. Tettnang hop pellets (2.2% alpha), 5 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 2 pkg. SafLager West European Lager yeast (S-23)

Target Parameters

  • Infusion mash to hit target of 152°, 60 minutes, batch sparge.
  • 1.068 o.g., 1.018 f.g., 6.5% abv, 27 IBU, 7 SRM
  • Water built from RO to hit target of 50 Ca, 5 Mg, 5 Na, 55 SO4, 70 Cl, 0 HCO3 ppm, RA -40

Procedure

  • To make my brewing water, I added 1.6 g gypsum, 0.3 g table salt, 1.2 g epsom salt, and 3.2 g calcium chloride to 6.5 gallons of RO water.
  • I mashed in with 3.15 gallons of water at 167° (and 4.75 mL of 75% phosphoric acid), to hit a mash temperature of 155°. After 40 minutes, the temperature was down to 152°. So, I added 0.65 gallons of water to bring the temperature back up to 157°. After a total of 60 minutes, I vorlaufed and collected the first runnings.
  • I added 2.75 gallons of water at 180°, let it sit for 10 minutes, vorlaufed, and drained the mash tun.
  • In total, I collected 5.5 gallons of runnings with a gravity of 1.049, for 78% efficiency.
  • I brought the kettle to a boil, adding hops and Whirlfloc per the schedule.
  • After 50 minutes of boiling, I measured the gravity and saw that it was at 1.058. This was well below my target, so I added 1.18 pounds of Briess pilsen DME to bring up the gravity.
  • After 60 minutes of boiling, I turned off the heat and chilled to 75°. I transferred to the fermenter, and put it in the fermentation chamber overnight to chill down to 54°. About 4 gallons of beer went into the fermenter.
  • I brewed the beer on 10 February 2018, and pitched the yeast on 11 February 2018. Prior to pitching, I hit the wort with 60 seconds of oxygen.
  • Starting gravity was 1.072.
  • On February 24, I let the beer free-rise to 64°. I’ll let it hang out at this temperature for a week or two before cold crashing.
