I did extract years ago, and they didn't turn out (extract twang), so I kind of gave up. Then last fall, I got back into it and went all-grain, learning about the importance of things like temperature control. I still had one canned extract kit (Cooper's Mexican Cerveza) on my shelf that had expired in 2011, but I couldn't bring myself to just throw it out, so a week ago, I decided to brew it just to see if I'd get anything remotely drinkable out of it. I discarded the kit instructions and yeast, added an ounce of Cascade hops, and fermented it at lager temperatures using some washed Czech Pils lager yeast. It's doing its D-rest right now, and if this batch turns out, then I'd be open to the idea of occasionally picking up a canned extract kit again in the future, if they were on sale or something.
It all depends on how this batch turns out. If it's bad or "twangy," then I'll stick with all-grain exclusively.
