I've been brewing beer for about 6 months now. I've done 10 or so batches all together and the last 4 have been all grain recipes rather than extracts. My beer is tasting better with each brew and I'm really starting to get the hang of certain things. I think it's time I start brewing more than 5 gallons at a time to start making it more rewarding. This is what leads me to my question. I've heard of people fermenting in their corny kegs before. Has anyone tried to use the other kind of keg as a carboy? What would the pros and cons of this be? I've taken apart a half barrel before and made a brew kettle out of it, it's something I'm sure a lot of you have done. I don't see why I couldn't dismantle a half barrel, quarter barrel, or even a 6th barrel, attach a blowoff hose and use it like I would a glass carboy. In fact it seems like a great idea, it would come with handles and would be easy to clean because it's stainless steel, and virtually unbreakable. Has anyone tried this? Are there pros and cons? Or should I just stick with glass and buy more carboys?
