I recently met a really serious brewer who said he will brew and evaluate a beer, and oftentimes just dump it if it doesn't live up to his expectations. Given that several iterations might be necessary to develop that perfect recipe, I can see the utility of this. I've never been scared to dump beer, especially since I make small batches. I wondered how many of you do this routinely? Its a waste in one sense, but as a hobby I don't think its much more expensive than any other and life's too short to drink mediocre beer. As long as you don't run short of course, which never happens at my house. I'd give it away but I don't know that many people who like homebrew, plus giving away beer that has one flaw or another (unless very slight) seems kind of wrong.
