I'm trying to brew a Scottish 60/ using the techniques in Drew Beechum's express brewing article from the Nov/Dec 2011 issue of zymurgy. I brewed this past Thursday night and pitched around 930pm. I used white labs wlp 028 Edinburgh yeast, a 1 liter starter was made. Fermentation was in a temp controlled freezer set to 65-67F. Today is the 5th day of fermentation and the krausen hasn't dropped yet. If I cold crash will the krausen drop allowing me to keg. I would like to have it on tap this Friday.
