10L strike w. 1g Gypsum + 3ml lactic
9L sparge @ 76C + 2ml lactic
Mash in @ 75C for 67C (45mins-60mins)
Mash out @ 77C

BREWDAY NOTES: Brewed 18/05/21,first brew at Sigynsgade (BIAB on induction stove top).
Water:
Cph tap +1g Gypsum
5ml lactic (3ml in strike, 2ml in batch sparge).
No further additions.
Mash:
Mashed in with 10L at 75C for 67C. Got 69C. Added 1L cold tap water for 66C.
Left for 60min rest (66C dropped to 64C by end of rest).
Mashed out at 68C (induction took too long to heat old dented stock pot).
Batch sparged with 9L (1L extra) and collected 16.5L
Kettle full = 16.5L @1.039//10P (target 1.031sg and 16.3L).
Boil:
Boiled for 1 hour 40mins. 30min whirlpool stand.
Induction either didn't connect well with the base of the pot or was underpowered. Took a long time to reach boil. Boil was very weak. Required the lid to be partially on for most of the time to achieve a significant hot break. Hot break skimmed off. Boil off volume =1.5L (100min boil).
No chill method used so hops were calculated as above but all times move forward 20mins (added as below).
20g fuggles @ 40 mins.
15g fuggles @ 5 mins into whirlpool.
25g fuggles @ 15 mins into whirlpool.
Pre-boil volume =16.5
- approx 1L trub left behind in kettle.
- approx 1.5L boil-off
= 14L to FV
OG: 1.041
Fermentation:
19/05/21
Pitched ~200-300ml of WY1318 slurry (from WP) into ~14L of wort @16.5C. (Wort was no chilled overnight outside to 16C). FV moved to basement (18.5C) and a wet towel placed around fv.

Brought bucket up from basement and into the spareroom of the apartment (21.7C). Left for 2 days for a diactyl rest.

Moved outside in the morning (outdoor temperature 16C). Prepared a gelatin solution, let cool. Added to 10C beer over night.
05/06/21
FG: 1.011
Beer left to stand at room temp (~21C) until now.
Beer priming: 62.6g table sugar in ~13.5L @23.5C for 1.9-2vol.
Actuals: 12.5L beer at ~23C with 62g table sugar (dissolved in 300ml ish of water) therefore theoretically a touch over 2.0volumes
