Hi Horace, I thought you were asking Chris the question. I leave the bèer for a week after fermentation on crash cool, drawing off yeast every other day. I can only get down to 3 deg during the summer then filter through a 100 micron then 30 and eventually 5 . After that I pass it through a membrane introducing a low level of co2 which helps keep the beer a little bit longer and gives a clear beer. The only clearing agent i use is 3 gram of copper fining to 100 ltr at the last 10 minutes of boil. I dont use isinglass!
