It's my beer and if I am bored or underwhelmed with it I'll dump it out if I damn well please.
My thoughts exactly. I am a decent brewer I think, but not great. I prefer great beer. As a consequence only about 50% of what I drink is homebrew.
I brew 5 gallon batches because it it is almost the same amount of time and work as for smaller batches, and (here's the real point) I fully expect my next batch to be stunningly good. I want a full 5 gallons of great beer! If I was intending to brew merely decent beer, I'd brew a six pack at a time.
The reality of my brewing prowess coupled with my drinking habits and apparent lack of family and friends coming over regularly enough to drink it gone, has me dumping a lot of beer. I'm OK with that. I'll always gladly make room for the next 50 point beer by surrendering a 35 point beer to the lawn.
