- Very clean and tasty, beautiful golden bronze colour.
I wanted to try an idea that I had read about on the brulosophy website about turning a Lager around in a relatively short time. The idea is pretty simple. You pitch as recommended (in this case 10 Celsius, 50F) and wait until the lager has reached 50% attenuation. Afterwards you then let the Lager gradually come up to a warmer temperature (in this case 18 Celsius, 64F) for the duration of the fermentation. In my case the Lager had fermented in ten days. It was then given another couple of days at a few degrees more for a diacetyl rest (more to do with paranoia rather than any perceived off flavours) and gradually reduced to cold crash temperature. The result was a very clean and tasty Vienna lager with no perceived off flavours.
