I want to try making a Quad for the first time. Basically following to same process as Allagash outlines in Brew like a Monk. My question is, how much pressure is needed to push to beer through a 1 micron filter cartridge. I don't own kegging equipment and am wondering if there is any other way to do this. Air pressure on a sealed pail? It will get new yeast for bottling. Thanks for any suggestions.
