Been reading that people have been having mixed experiences with their auto syphon... I've never used one myself, but i've seen here that an air bubble sometimes forms in the hose. My question is if this little airbubble in the hose is enough to "oxidize" the beer. Seems to me that that amount of O2 is quite minimal and shouldnt have a detectable affect on the beer. At least not enough to oxidize the beer within a couple of weeks... i would think!
If thats the case, this little staling beer problem seems to be a little mystery to me! Please keep us posted on how future batches turn out, wingnut!
If the problem is due to something in the brewing/fermenting process, or moving of the beer, it would be a little silly in spending a bunch of money on kegging equipment if the end result turns out the same. I currently only bottle my beers, and they have a shelf of about a year and counting. Dont think kegging will be a quick fix for this problem.
