I’ve enjoyed my Mexican-style pale lager recipe over the years, which has followed the same core ingredients but with variations in how I handle the corn. This includes either flaked corn directly in the mash or grits in a cereal mash. The latter is a lot of work, but opens up varieties of corn and subtle flavors not possible with the standard flaked ingredients. So, I aimed for the extra effort of a cereal mash on this iteration.

This particular batch was brewed to celebrate the major accomplishment of a friend who defended her master’s thesis (I served on her committee as a outside member, too). She had shared that even though she’s not really a beer person, the original version of this recipe was a favorite of hers. That was all the excuse I needed to return to the cereal mash!
Alta California Lager 2026
- 5.75 lb. Synergy Select pilsen malt (Briess)
- 2 lb. white corn grits (Palmetto Farms)
- 1.75 lb. Vienna malt (Weyermann)
- 0.5 tsp. BrewTanB, added to mash
- 0.4 oz. Magnum hop pellets (12.3% alpha), 60 minute boil
- 0.5 tsp. BrewTanB, 10 minute boil
- 1 Kick carrageenan tablet
- 1 oz. Saaz hop pellets (2.4% alpha), 5 minute boil
- 0.5 tsp. WLN1000 yeast nutrient (White Labs), 5 minute boil
- 2 pkg. Diamond Lager yeast (Lallemand)
Target Parameters
- Infusion mash, with 75 minutes at 148°, and 10 minutes at 168°, with cereal mash at first step; full volume mash
- 1.044 o.g., 1.006 f.g., 5.0% abv, 21 IBU, 3 SRM
- Water built from RO, to hit 20 ppm Ca and 35 ppm Cl
- 5 gallon batch
Procedure
- The first step in the process was a cereal mash. I had intended 0.5 lb. of pilsner malt (as did in my first batch), but mismeasured and had 1 lb. instead. I combined ~0.75 gallons of RO water with the corn grits and pilsner malt, heating the mixture on the stove to 158°. I held the mash here for 10 minutes, before bringing everything to a boil. During a 30 minute boil, I added another 0.5 gallons or so of RO water.
- In my Anvil Foundry, I started with 6.25 gallons of water, to which I added 1.5 grams of calcium chloride. I heated this to 140°.
- During the last 7 minutes or so of the cereal mash, I mashed in the rest of the grains to hit a temperature of ~130° degrees. Then, a few minutes later, I added the boiling cereal mash. This heated the entire mash to around 145°, and then I added heat via the Anvil heating element to get up to 148°. I added 2 tbs. of 10% phosphoric acid to adjust pH.
- I held the mash at 148° for 75 minutes, before raising to 168° for 10 minutes.
- At the end of the mash, I pulled the grains. The runnings came out to 6.56 gallons at a gravity of 1.038, for 73% mash efficiency.
- I heated the runnings to a boil, adding hops and finings per the recipe. At the end of the 60 minute boil, I turned off the heat and chilled the wort to 74°, before transferring to the fermenter. I chilled the fermenter the rest of the way in the fermentation chamber, down to 50°. 12 hours after the initial transfer, I pitched the yeast directly.
- I brewed this beer on 9 April 2026. Starting gravity was 1.045.
- The fermenter was held at 52° for fermentation, and it was cold crashed to 34 degrees on 4 May 2026. I kegged the beer on 9 May 2026, using a semi-closed transfer. The beer was slightly hazy at this point, with a very slight fruity aroma (corn?).
- Final gravity was 1.007, for 5.1% abv.

Tasting
- Appearance
- Light straw yellow beer, with a modestly persistent white head. There is a very slight haze to this, which is annoying (especially given how long it has been lagering).
- Aroma
- The beer has a gorgeous aroma, with a light cracker and corn character. No hop aroma to speak of, nor is there any yeast character that I pick up.
- Flavor
- Medium-low cracker-like malt flavor, with a hint of corn sweetness. Medium-low bitterness, clean fermentation profile. Evenly balanced.
- Mouthfeel
- Light bodied, crisp mouthfeel, medium-high carbonation.
- Would I Brew This Again?
- This is an incredibly tasty and very drinkable beer; it hits pretty much all of the flavor and aroma notes I was hoping for. The sensory contribution from the corn is subtle, but absolutely perfect. I love this recipe! The only minor annoyance is the persistent haze. I need to figure that out in my next batch, because it has been a perpetual issue in most iterations of the recipe. Maybe I need to change water chemistry, and increase the calcium chloride dose? At a minimum, I should hit the keg with a clarifier next time.
- Serving mod: my friend tells me that the beer is delicious with chamoy and tajin on the rim. Now I have to try this!
- Overall
- 8/10
