Notes

KETTLE SOURING:
-Mash at 152F for 60-70 minutes
-Boil for 15 minutes (to kill everything and de-oxygenate)
-Lower pH to 4.5 and cool to 100F (be careful - we don't want oxygen or any unintended bugs to get in, keep lid on and stir very gently if at all)
-Pitch in LAB, place Saran Wrap over top & purge space with CO2
-Seal the Saran wrap, place kettle lid on top of the wrap to really seal it off, and insulate (wrap in a bunch of towels for me)
-Check every 12 hours (temperature and pH). Raise temp back up to 95F if it drops.
-When pH of 3.0-3.5 is reached (3.35 seems great), it's done

POST KETTLE SOUR:
-Boil for 15 minutes with hops (kill everything & add bitterness)
-cool to 68F, pitch yeast, and allow primary fermentation to nearly complete / complete (5ish days)
-Add prepped raspberries (either transfer to secondary, or be super careful to not splash! cannot have any oxygen getting in)
-Allow 2 additional weeks, cold crash, transfer to bottle bucket using a filter
-Carbonate to 2.5vol

RASPBERRY PREP:
-1lb high-quality raspberries per gallon
-Wash very well, chop up with food processer, and freeze them (kills everything & breaks down cell walls)
-Thaw before adding

Kettle Sour started 8/21 evening (4.6pH start), finished 8/23 evening (3.35 finish). OG = 1.052, mash ran pretty hot (156F) so a bit concerned about final gravity
