Notes


DOUGH-IN
Time | 2:43p - 2:53
Consistency | VERY THICK; need more water next time
Temp | 161F

MASH

VORLAUF
Time | 3:30p - 3:57p

LAUTER/COLLECTION
Time | 3:57p - 6:45p
Temp | 154F - 210F; got too hot
Note | Recirculated first wort briefly at 4:05p-4:10, then intentionally recirculated to capacity at 4:35p when filter was visible. Wort was at 175; DO NOT REPEAT

SPARGE

Volume | 1st - > 1gal.
2nd - 1gal.

Note | This was my attempt at fly sparging, next time I might try batch sparging (or re-mashing). Need to do more research.

BOIL
Collected vol. | 6.25gal.
Pre-boil gravity | 13.25
Note | Pre-boil at 7:15p 5lb of DME was added, bringing the volume up to 7gal. and the gravity to 21.25.

2nd (last) hop | 9:00p
Post-boil volume | 5.55gal.
Note | At 8:57p I turned on both heaters. Unsure whether I should repeat, might want to stick to just the 1000W heater.
