Berliner Weisse: 10 gallon recipe

(Somebody needs to tell the Nazis to stop inbreeding for a while.)

It's a nice spring day here in NY and the birds are chirping. Pretty soon it will be hot out: Time to start thinking about summer beers! With the new Wyeast Berliner weisse seasonal strain out, this brew was a no-brainer.

The recipe is largely based off Jamil's Berliner weisse recipe. But at 1.032 OG, it is possible to brew 10 gallons all-grain on a 6 gallon system. So that's what I did. The only snafu was as usual, I didn't check my grain supply thoroughly enough beforehand, and didn't have quite enough wheat. So this recipe is about 30% wheat.

Recipe is for 10 gallons in the fermentor, all grain, with a 6.75 gallon boil, diluted after cooling
OG 1.032 F.G. 1.005 IBU's 4.5

8.75 Weyermann Bohemian Pilsner malt
4.25 lb. wheat malt
.5 lb. rice hulls

50 gr. Hallertauer pellets, 4.6%AA at 15 minutes

Mash: 4 gallons of water + .5 ml lactic acid to 161
Mash in to 149, hold for 75 minutes.
Add heat and mash out to 168 over 15 minutes.
Total mash time 90 minutes.

Sparge with 5.75 gallons + .25 ml lactic acid at 172
Collect 6.75 gallons at 1.055 = 75% efficiency

Boil time = 15 minutes
Hops and 1 whirlfoc tab at 15
3/4 tsp wyeast nutrient at 10 min

Chilled to 68, whirlpooled, and collected 6 gallons (3 per carboy) at 1.057
Diluted to 1.032 with 2 gallons of water per carboy.
Aerated and pitched yeast at 66 degrees
Will ferment at 68 degrees.

Pitched a 2 qt. starter of Wyeast 3191, made 2 days beforehand and shaken periodically.

Fermented at 68 degrees for 6 days, then I let it warm to room temp (72).
I kegged 1 batch after about 2 weeks in the primary. I secondaried the other batch with the intention of bottling it.

5/8/08 The keg and the batch in secondary are both hanging out at room temp, which is about 77 degrees right now. Sampled a taste from the secondary. Quite nice but still lacking in lactic sourness. I hop it gets more sour or I'm gonna be pissed at Wyeast!

5/26/08 Bottled the other 5 gallons with 6.5 oz of priming sugar. It is starting to taste nice, and actually fairly bretty.
