The Bay All Day NZ Ale Brew Session

BREW DAY Increased Grain Bill by approx 3 kg to hit OG - Starting Fresh - recalculated water infusion steps (need to calculate mash tun efficiency today) - mashed at 66 for 60 mins - mash strike volume = 43L - HERMS circulated mash every 20mins to maintain heat and create grain bed - lautering at 1.5L per min - Used 30L Pot Lid for Fly Sparge on top of grain bed (started sparging 15 mins after conversion to boil kettle) - sparge water temp is 74 - lauter took nearly one hour - grain bed was well settled but a large channel on HLT side maybe from pot lid sparge? - pre-boil OG is 1.67 (at room temp) - Brewhouse efficiency calculator suggests the BBC Mash Tun efficiency is 'off the charts' - MASH TUN EFFICIENCY IS ?? - Boiled for 60 mins - hops included as per recipe plus Irish Moss included with Flavour hops - NO hop bag used - NEW inclusion of false bottom in Boil Kettle - post boil OG of 1.060 - topped off with 2.5 to 3L of filtered cold water to reduce down to 1.55 OG - Put fermenter in final position - i.e. NO unnecessary movement after pitching yeast FINAL BATCH SIZE = 56L WHAT WE COULD DO BETTER - Add about 1.5L to 2L to sparge - Reduce Grain bill slightly - 4L short in the batch size? need to increase the boil size by 4L to 6L (we added 2 to the wort and fell 4 short) PRIMARY FERMENTATION SECONDARY / CONDITIONING BOTTLING
