This has probably been discussed before, but I couldn't find the topic when searching, but is there any issue transferring beer currently in bottles to a keg? The reason I ask is that I have a case or so of NB Karl's 90 schilling that I bottled in September and it's still not carbed, well not consistently. Some bottles are fine, but others are really under carbed. Because of this I moved to kegging and kegged my last beer (NB Caribou Slobber) and it turned out great. So I'm thinking about transferring the remaining Karl's 90 beer from the bottles to a keg, clearing the head space of oxygen and then carbing it like any other beer.
