It was spring 2008. I made a Blonde ale which is my regular house ale. Nothing I did was special, but I did forget to turn on the fermentation chamber. The next morning I checked it and the temp was 74F. Nottingham yeast. I crash cooled it and got it down to 68F in an hour or so. The beer turned out great, at least for a Blonde Ale. I have never repeated it since then.
