I still buy commercial beers, but mostly it's stuff I don't make myself, or it's from a local microbrewery.
I don't think I can drink 5 gallons of creme brulee stout, but I love the occasional bomber, I don't have beer gas, but still like Guinness draught every now and then. Switchback is amazing, so I'll buy a keg every now and then to hook into my setup, and long trail blackberry wheat is one of my all time favorites, so yeah, I'll pick that up from time to time. Angry Orchard crisp cider is my go-to when I'm at my favorite establishment, although I have a cider recipe and have a keg of edworts apfelweine in the keezer right now. Connecticut is going through this micro-brewery phase and it's freaking awesome, we've had three open in the past year in my area alone, not to mention the ones that already exist - needless to say I'm patronizing them whenever I can - there is this concord grape saison at Shebeen that is easily the best thing they put out.
I have never felt guilty about buying beer, not even when last Friday I was at a hockey game for $2 brew $1 dogs night - I had 4 Buds before the second period because they were much cheaper than the $9 SA's. I also had 4 hot dogs before the second period, but that's not that much of an achievement, and I could have easily eaten more.
