This past weekend I got to be Duncan’s Brewing Assistant for what was the single largest brew day I have done to date! We brewed 20 Gallons of IIPA over about seven hours and it was a beautiful thing. Duncan borrowed Rob’s massive 156L Mash tun allowing us to do a full mash and fly sparge of the whopping 28kg Grist, which I must say has given me a whole new respect for the mash PADDLE! the poor spoon barely held up at one point and we had a notable dough ball explosion but Duncan jumped in with a spatula and I kicked it into high gear whipping the grains into saturation.
Anyway getting back on topic, the brew day was very smooth although it was the largest single brew day I have done to date but it was very relaxed and enjoyable. Duncan said we hit the numbers with a 74% Efficiency and that really puts a smile on my face as now I am getting quite confident in the over all brewing process.
When I first started brewing one gallon all grain batches everyone laughed and said it’s the same work to do five as it is 10, and they are absolutely right in that. An average brew day runs about hours for me and that includes complete setup and cleanup of my equipment and the big brew day we were at it for about seven and a half hours all in. I’m not saying don’t do the little batches because sometimes you only want a sample before you commit to a full five or ten gallons, but remember it’s all the same motions and steps just with a lot more liquid and grain.
The resulting wort from this brew day has been split into multiple batches with some brew day secrets I cant disclose at this time (I will later on though, so don’t worry) 😛
