I have used it in the past and had an absolute great pilsner turn out. I fermented at about 50 F but I've heard mixed opinions on this yeast at any temperature. I'm currently remaking that awesome pils I made a year ago but my cold room is at 40F right now not 50F. Thoughts on fermenting a pils with this yeast at 40F? I have yet to get a fermenting chamber so control over the temperature is out of the question at the moment.
