Märzen and Rauchbier Double Brew

Double brew day. Doing two lagers in one day makes better use of the lagering fridge, which is big enough to fit two 5-gallon fermenting vessels at once.

------

7/16/17: Brewed, hit mash temp pretty well, maybe a degree or so too high. Got ~ 7.7 gal, 1.046 preboil, ~6 gal, 1.060 post-boil. May have boiled slightly too long or short since I somehow accidentally pause the timer for a few minutes.

Cooled to 100F with recirculating IC, allowed to settle, racked clear beer to sanitized plastic carboy. Placed in fridge at 45F target temp.

Measured OG of left-over wort at ~ 1.060. Tasted smoky but not overwhelming. Wort was darker than that for the Märzen.

7/17/17: Pitched 2 packets of S-34/70. Did not rehydrate. The directions on the packet say only to sprinkle into wort.

7/19/17: Good krausen and airlock activity at 50F.
 
Both:
8/12/17: Kegged Märzen and began force carbing, racked Rauchbier to secondary. Both had gone through D-Rest and subsequent cooling to 35F in the primary while I was away on vacation.
