When the first time you pour a homebrew for a buddy and the one bottle you pour had something wrong and didn't carb.
I have been enjoying said brew for a week and a half with no problems, but it just so happened that the one bottle I poured ( now keep in mind, I only have 2 brews under my belt and am still happy when anything comes out right) had no head and no carb. Probably a bad cap job, but still pretty embarrassing, eh?
This was my first recipe on my own, and it was pretty tasty too. But all he remembers is....no fizz.
It's a nice German lager with good mouthfeel and a nice balanced malt vs Saaz hop taste. He said it tasted good, but...
