The intention of this brew was to improve Goto Statement by increasing the bitterness and reducing the mash temperature. Both of these changes went well but a simple error meant the whole batch was ruined.
It appeared that the fermentation temperature was too low, sitting at 10-12 degrees for the first couple of days. The solution I thought was to tweak the temperature control algorithm to increase the temp. The actual solution was to put back the probe that had fallen out of the fermenter onto the garage floor – doh!
The consequence of this mistake was that temperature was above 35C for at least a day. I hoped for the best and let it take its course. Alas it was full of fusel alcohols that tasted harsh. These off flavours never subsided over a month an I accept it will have to go down the drain.
