-What was your OG/FG, fermentation temp? This sounds like a very short primary fermentation for a tripp.
- how did your friend’s “go bad”? Done with good sanitation, homebrew is usually good for a long time. Years. One of the best beers I’ve tasted, commercial or homebrewed (if I do say so) is a Rye IIPA I made in 2009 and found a bottle of in January 2012.
short answer: sanitize up and taste it. If you like it, bottle it and drink it!
longer answer: way too early for a trippel. People age these for years before drinking them. I brewed up a 1.15 monster last January and its still maturing.
If your getting antsy, brew up something else with a quick turnaround (or a couple…hefe, ord. bitter, APA, Belgian Pale Ale). This one likely has a long way to go.
