I "failed" a new brewer, and I didn't even have a chance to help. A friend of a friend on Facebook remarked that he was sad that his porter was too bitter. I shot him an email telling him to stash the bottles in a cool place (65-70F) for a month and to try it again.
Turns out he was talking about the flavor post-fermentation and pre-bottling!
He bottled up a 12er to see how things turned out and then TOSSED the rest.
He is now a "friend" of mine via FB so I'll get him doing some reading before we lose a newb to the finest hobby ever.
I know he is going to be very disappointed when he cracks open one of those bottles and realizes he tossed almost two cases of good tasting brew down the the drain.
