Mash Notes: Used in some authentic German styles. Attempt to draw decoction from the thickest portion of the mash. Profiles vary. Some traditional German mashes use a long acid rest at 40 deg C. Also some sources recommend the decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.

– Brewed @ my apt. Had to add a gallon of boiling water (after the decoction) to bring the temp up to ~149.
– Used ghetto incubator to keep the temp of the lacto starter @ around 85F for 2 days.
– Ended up w/ more than 5 gallons. Chilled to 90F and added lacto to carboy, then racked the beer on top.
– Added the yeast before going to bed.
– Forgot to add the ounce of hops to the mash…

– Bottled today. Added a little bit of yeast, and a whole container of lacto to the sour bottling bucket. Added 7oz of sugar to hit ~ 3.8 volumes. Ended up w/ ~5gallons. Bottled up 26 12oz and 12 22oz.
