The whole brewery. It's in the front third of the garage. The back bit is a utility room. I put the partition up.
The actual brewery bit. It has two 70quart Igloo coolers, a 75L Brupaks boiler with 2x3kW elements and two pumps. Currently it I haven't built the RIMs bit so today's was just a test of the core bits.
Anyway today's recipe was a light pale ale. Here's the recipe.
20L of SG 1.035, 29 IBU, 4 SRM
Lager Malt 2.72kg
Caramalt 230g
Melanoidin Malt 80g
Mash at 65 for an hour
Amarillo (9%) 15g all of boil
Amarillo (9%) 15g last 15 mins
Amarillo (9%) 10g at turn off.
Boil 1 hr. ferment with safale-04.
I really like Amarillo by Crouch vale brewery so this was an attempt at a light version of it.
The Brew Day
First crush the grain using my new mill. It's a barley crusher that I got from the states. Quite reasonable price including shipping and worked a treat.
The mash tun is fitted with a manifold and a recirculation thingy. I plan on batch sparging.
I loaded the grain into the tun dry and then pumped the water through the manifold (underletting). This worked great - no lumps. Sadly however the strike water was too cool (75C) and the mash temp ended up at 60-62C and I never really got it any higher even by adding boiling water. In future I should heat the strike to 80C. This beer will probs be a bit drier than I was intending.
The batch spage was uneventful and the boil was on the go. The two elements made short work of getting to the boil and got the 24-ish litres to boiling in about 15 minutes. Once at the boil I turned off one of the elements.
It looks a long way to the bottom....
I used an immersion chiller to cool the beer which worked OK but most of the coils were out of the wort as the chiller is designed for much more wort.
The beer was pumped into the fermenter and pitched with Safale S-04. I got about 1.033 which was a bit low but I ended up with about 2 liters more wort than I intended so the efficency was about what I expected 75%-ish.
Lessons learnt
1. If the mash tun and the grain are both very cold then you need to increase the strike temperature to about 80C.
2. Or build that RIMS!!!
3. The kettle losses after pumping out the wort are about 1-2 liters. This is quite a lot on a 20L beer - brew more beer!
But you've learn the lesson now
