The first beer I brewed was kit beer (Bock) with LME, grain, and some type of dry yeast. I read the instructions and followed them until it said to bottle. Following them was the problem. While I do not remember the exact wording, but after stepping grains, boiling wort, adding hops, the instructions stated to cool the wort to 80 degrees, add yeast, wait 4 days and then bottle.
Coming from a wine background, 80 degrees for pitching yeast seemed fine. So, I pitched the yeast and watched over the next two days at one of the most vigorous fermentation I had ever seen. Fermentation temp? All above 80 degrees the entire time At 4 days, I decided that I really did not want to bottle, so I transferred to a secondary and put it in a 65 degree room, but the wort stayed in the mid-70's most of the time.
Left the beer in the secondary for 7days and tasted it. I was bad - real bad. Like jet fuel. Bad alcohol tastes and smells everywhere. I thought the beer would be ruined, but remembered some of the bad wine I had made in the past that turned good. So, I transferred to a bottling bucket. About half-way through the transfer, the secondary slipped off the wedge it was on, which disturbed the turb, meaning I got quite a bit of it in the bottling bucket. I was already upset with the beer, so I said screw it, I'm not waiting for the turb to settle again, added corn sugar to carb, and bottled it.
The beer spent a month in the bottle in a 65 degree room before I put some in the fridge for a week. When I tasted it, it still had an alcohol taste, and a semi-unpleasant after taste, but overall it was somewhat drinkable. Two weeks later I put more in the fridge and left it there for a two more weeks. What I found was that the beer had morphed into some really good beer that even my wife liked. It just seems that as time went on, the beer just got better and better. The only complaint I had with the beer was a very slight plastic/alcohol type aftertaste when breathing out (or burping), and a prominent layer of sediment from the turb that I disturbed when transferring.
So, I would say that with all the problems I had, my first beer was a success. I also learned that time heals all sorts of bad things.
