Batch 206, Leeser

This was supposed to be a double batch day, but I tried to kill myself with CO, so just one today, and another tomorrow. Must remember to turn on the fans in the beer shed, or splitting headaches will happen. Just to be clear, I wasn't trying to kill myself. My beer shed is 12' x 20', has two windows with a fan in each, a big door, and a high volume roof exhaust fan. It was cold, and I didn't turn on the fans, big mistake.

Anyway, a 10 gallon batch of Leeser, pretty straightforward.

23.75 lb pilsner

Mashed at 146F for 60 minutes, adjusted pH to 5.2, recirc (vorlauf, for you German speakers) for 10 minutes each sparge, collected 12.5 gallons in the boil kettle.

1.5 oz Magnum, 60 minutes
2 tsp Irish Moss, 15 minutes
3 oz Saaz, 5 minutes

90 minute boil

I used a mix of Wyeast Bohemian Lager yeast and White Labs Oktoberfest yeast in a 2 quart starter. Only 1 quart went into this batch, the other quart is for tomorrow.

OG was 1.050, which is low again. I'm going to check the roller gap on my mill before brewing tomorrow.

Update, Nov 17, 2017, we got back from vacation on Monday, so I bumped the temp on both this batch and the Oktoberfest to 65F for a diacetyl rest, then dropped the temp to 35F to cold crash out the yeast. Kegged both this batch and the Okto, both are now lagering at 35F until spring time.
