Last weekend I brewed my favorite beer, Piper’s Irish-American Red Ale. I’m sure the beer will turn out fine, but the brew didn’t go as planned. I’m still struggling to get my mill to consistently produce a good crush, and I think my low yields this time around is almost certainly due to the mill. It’s a three roller mill; the first two rollers do a basic crush at a fixed gap, and then the grains pass between one of the top rollers and a lower roller that’s adjustable. For some reason, the grains sometimes come out between the lower roller and the wrong upper roller and they don’t get crushed a second time. Strange.
The big change with this brew was using Creek water to chill the boiled wort down to fermentation temperature. I’d assumed the Creek would still be very cold, but after pumping up twenty gallons, I discovered it was a balmy 55°F. So I pumped up another ten gallons in the hope that it would be enough to chill the wort. Not quite. I got it down to 72°F, which is pretty amazing, but I would have preferred something between 64–68°F.
Still, it was a nice relaxed brew session, and thus far Piper’s has always come out fantastic. We’ll know in about a month.
The other thing I’ve noticed is that the red cabin is starting to get too warm for primary fermentation. At our old house the garage temperature never got much above 60°F even in the summer, so I’d always do the primary fermentation in my insulated box, heated with a light bulb on a temperature controller. Luckily, we kept the old fridge that was here when we moved in and it’s keeping a nice stable 65°F on the same temperature controller I had been using to heat the fermentation chamber. Now I can ferment in the summer, and even experiment with lagering, which is a whole area of brewing that I’ve never attempted in all these years.
