I've been brewing for over a year, and am nearing the spot where control and proper monitoring are important. So I've been pulling samples more frequently, and racking with an auto-syphon. However, that involves opening my lid to pull those samples. This exposes my beer to greater risk of infection. I own a racking cane, but haven't tried to use it. Something about it escapes me. How do you start the feed process? Do you hook an auto-siphon to the end of the cane with hose in and hose out? Is there some magic gravity procedure? Thanks.
