I love it when I have honed a house recipe, and altbier is one of my annual favorites. This is largely similar to what I made previously; the 2024 version is my fifth brew of the recipe! Compared to last year, I altered the CaraMunich addition to include a blend of Caramel Munich 60L (Briess) and Caramunich II, versus just Caramunich I as I did last year. Because the 2023 version was a bit harsh on bitterness, I swapped out the Magnum hops and went with Spalt alone for the hop additions. Finally, I used a blend of K-97 and Köln dry yeasts; sadly, Köln’s days are numbered in my brewery, because it has been discontinued by Lallemand.
Alstadt Alt 2.2
- 6.5 lb. pilsner malt (Rahr)
- 1.5 lb. Munich I malt (Weyermann)
- 1.5 lb. Vienna malt (Weyermann)
- 0.5 lb. Caramel Munich 60L (Briess)
- 0.5 lb. Caramunich II malt (Weyermann)
- 2 oz. Carafa Special I malt (Weyermann)
- 0.5 tsp. BrewTanB, added to mash
- 2.0 oz. Spalt Spalter hop pellets (4.3% alpha), 60 minute boil
- 0.5 tsp. BrewTanB, 10 minute boil
- 1.0 oz. Spalt Spalter hop pellets (4.3% alpha), 5 minute boil
- 1 Whirlfloc tablet, 5 minute boil
- 1 pkg. Köln Kölsch Style Ale Yeast (Lallemand)
- 1 pkg. SafAle German Ale yeast K-97 (Fermentis)
Target Parameters
- 1.048 s.g., 1.011 f.g., 4.9% abv, 35 IBU, 14 SRM
- 60 minute infusion mash, full volume, 152°
- Claremont tap water treated with Campden tablet
Procedure
- I mashed in with 7.5 gallons of water at 157°, to hit a mash temperature of 152°. I added 4 mL of 88% lactic acid and held the mash here (with recirculation) for 60 minutes, before raising to 168° for the 10 minute mash-out.
- After removing the grain basket, I had 6.5 gallons of wort with a gravity of 1.043, for an efficiency of 71%.
- I brought the runnings to a boil, adding malt and finings per the recipe. After the 60 minute boil, I chilled to 80° and transferred to the fermenter. I let it chill a bit down to 60° in the fermentation chamber, before pitching the yeast and setting the fermentation temperature to 64°. I ended up using a mix of yeast, because the K-97 was a year past expiration.
- I brewed the beer on 11 August 2024, and it had a starting gravity of 1.051.
- I let the beer free-rise to 66° on 22 August 2024, when I started fermenting a pale ale. Finally, I let the beer finish at ambient on 22 August, around 75° to 80°.
- I kegged the beer on 23 August 2024, and it had a final gravity of 1.011. This works out to 5.3% abv.
Tasting
- Appearance
- Deep copper color, very clear, with a fine and reasonably persistent ivory colored head.
- Aroma
- Bread crust malt aroma at the front, along with dark caramel. A slight touch of spicy hop aroma.
- Flavor
- Relatively bitter beer; malt flavor is of dark breadcrest and rich mattiness. I pick up some dried fruit character, from the malt/yeast interplay.
- Mouthfeel
- Medium body, medium carbonation, slightly dry finish.
- Would I brew this again?
- This remains a wonderful althier recipe, despite slight tweaks over the years. It took a bit of time to clear, but is now fantastic! I love this beer!
- Overall
- 10/10
