I cracked open a bottle of my first succesful batch. It's an LME brew based off an amber ale recipe. It is beer, and it is drinkable, but not exactly an award winner.
The pros: The color and body came out right. The beer properly carbonated after spending two weeks in the bottle, and the OG and FG were within .01 of what I had anticipated.
The cons: It has a yeasty flavor, and doesn't taste as anticipated. I left it in the primary for about 15 days.
