Double brew day of lagers, since it makes sense to use my chest freezer to do two lagers at once. Unused capacity is inefficient.
Made starters on 12/31 using yeast leftover from previous brews. Both were fermenting by the next day.
Brewed 1/2/17.

Hit mash temp and boil volume well, ended up with around 6.75 gallons post-boil, with gravity right on at 1.052. Racked to carboy at 110F, let cool to 45F in freezer, oxygenated for 45 seconds, and pitched most of the starter on 1/3/17. Wort sample was tasting good.

Brewed 1/2/17.
Had to use my old pot, without volume markers. Under volume. Got around 5 gallons of 1.060 wort into my carboy, so under volume. Cooled to 45F, oxygenated ~45 seconds, and pitched the starter on 1/3/17. Collected the trub from the kettle, put in freezer, then sepwrated around 1 quart of clear wort from the trub, boiled briefly, cooled and added it the carboy. Did the same with 1 quart of Czech Dark lager but added it to the rachbier.
