I enjoyed brewing but here are a few things I don't like:
If your going spend the time you may as well do a 5 gallon batch. With a 5 gallon batch, your talking 50 bottles of beer. I like a lot of variety.
My results were just average. I would rank Miller Lite, Bud Light, etc. a 1.5. I would rank most of the beer I made a 3. The problem is that there are so many 4+ craft beers out there that I like. I've also tried other peoples home brew and none of them were great IMO. I'd rather take the money that I was spending on brewing and make a beer run to pick of some beer from Toppling Goliath, 3floyds, Bells, Surly, etc. that tastes a lot better than I could produce.
I will say that it was great learning experience and made me appreciate the work required to make a good beer.
I'm a pretty big beer nerd, drink a lot of different beer, pretty active in trading beer on BA and people ask me all the time if I brew. I tell them absolutely not. I do not have the patience required to overcome the learning curve. I want to start at the top and that's just not possible. I would rather spend some money, buy some quality beer, drink it and not have to worry about it. I'm sure its a great hobby and I'd love to brew with someone some day, but its just not something that I've got a burning desire to do right now.
