Preboil volume was 15 litres with BRX 9.2 1037 which is close. IMash was at around 63c (145F) for 45 mins then up to around 68C (154F) for the last 10 minutes.
Boiled for around 55 mins until 11L left. WHirlfloc added after 35-40 minutes. Flameout then very minor chill to 75x. Added hops for around 35 minutes. Removed hops. Chilled to 22C took around 20 mins.
Tried a whirlpool but not especially effective so the fermentaor has a lot of trub in it. Used the 2112 yeast brough up to room temperature and added a small amount of mangrove jack californian common yeast. made sure there was plenty of aeration. I'm not sure how much 2112 yeast there was. To me it looked like a fairly small amount.
Cooking at round 20-22C indoors for maybe 18 hours then moved to the garage. Temp still around 20-21. Will try and keep it at 18 overnoght
Post boil BRX was 12.85 (1052) but after adding to the fermentor it read 12.3 or 1050.
Started cooking fairly quickly and still going strong after a day.
After 2.5 days fermentation seems to have stopped. BRX reading is 5,7 5,8 or 1007 equating to around 5.7% which is quite a bit higher than expected
