The warm British summer this year hasn’t been ideal for someone who makes beer without the advantage of any cooling equipment so brewing has taken a bit of a backseat for the past couple of months. The temperature however has recently dropped, convenient as we were out of beer.
Last weekend I brewed a small batch of an American Pale Ale I’ve made before – I still had all the ingredients sat in the cupboard so this didn’t even involve any shopping!
I managed to get some eco-friendly insulated packaging material that was being chucked out at work – its just wool in a plastic bag, designed to keep things in the post cool, but I figured it would be useful for wrapping my “mash tun” in to hold temperature more efficiently. My current mash tun is just a stainless stockpot, which holds temp fairly well for 60 minutes, but I was hoping this wool would help improve this again….if only I had remembered to check the temperature at the end of the hour!
I used Beersmith3 to track the brew, I hit most of the predicted values for efficiency and gravity with the exception of the gravity once the wort was transferred into the fermenter – looks like this beer will turn out a little weaker than expected, that’s no big deal though.
A few hours brewing and almost a week later and 5 litres of beer are still bubbling away nicely in our utility room – temperature in there has been holding at a useful 21C or so which is ideal fermenting temperature. I’ll add some hops in the next day or so and then look to start transferring to bottles in another week.
