My approach is quite the opposite. I get an idea for a future batch and try a few commercial samples of a similar style. Then I think to myself, how can I make something better?
Just as I thought I had perfected my IPA recipe for my liking, I tried a commercial IPA I hadn't tried before and instantly wondered how I could tweak my recipe to create the same level of smooth bitterness as that one.
Personally, I would never stop drinking commercial beer. I do buy it less often, and it's mostly for research purposes. Or at least, that's what I tell my wife
