BREWING NOTES:

TASTING NOTES: 20 litres of bottled water didn’t come up to the 20 litre marking on the Braumeister, but it really needs to so that the heating element stays submerged. 5kg of grain mashed in OK. Efficiency much better than expected at 79%. Airlock activity after 12 hours. Barrelled on 29/09/25 in an ex-sherry barrel with 10x 250ml bottles. Forgot to Co2 purge the barrel.
