Thanks fall-line. I used Safala s-04 dry ale yeast and my fermenter thermometer is reading 72 degrees which is at the high end of but should be OK. You're probably right, I'm using a 5 gallon car boy, maybe I should invest in a 6 ;-). It's too cold here in Oregon right now to ferment in my shop...
I recently brewed my 2nd all-mash brew of the McMennamins Ruby Ale clone (the first batch didn't turn out at all). I placed it in the car boy last Thursday and added the dry yeast. By Friday afternoon, it was fermenting very actively and I probably lost about 1 gallon in the overflow bottle...
