I purchased a 3 tier gravity fed system a few months back, but so far I have only had on success, an oatmeal stout. The five other beers I have made have all the same sort of off taste, yet they are still consumable. I am moving and forced to give up the brew stand, but hate to part with 3 keggels because they are hard to come by in Hawaii. The keggels however all have rust around their valves. Is this may be affecting the taste of my beer. I know the possiblities are endless, but are the Keggles worth retaining?
I still plan on brewing, but may start extract brewing again. Will I regret moving backwards in the brew game? Has anyone had a similar experience?
