One of the great things about this site is that it seems everyone here all either has the same issue at some point in their brewing career, or have the experience to help lend some good advice.
Like this. I just bottled my 6th batch on Saturday. An extract version of a simple chocolate ale (porter?). Before I bottled, I opened up my brewlog for the batch, and saw that I brewed it 3 months prior, nearly to the day!
I instantly freaked, I thought for sure it was only just over a month. I figured that it probably didn't matter much, so went along my merry way getting ready. Since the bottling process hadn't been done in /evidently/ 3 months I spent extra time cleaning and sanitizing.
I really did imagine I'd open the primary (no secondary, this was 3 months in primary) and discover some bad looking gunk all over the surface. What I found however was actually just a 'few' spots of what I'd imagine were floating yeasy colonies, similear to what I've seen in my other fermentaiton buckets at bottling time. In fact, there were FEWER of them than in other brews I've done, and the sometimes 'skin' that forms on some types wasn't there either. It smelled like beer of course, so bottling we go!
I guess I'll know for sure in at least 3 weeks, but I have high hopes. Actually, even if it isn't great, the experience is worth everything. I'm loosing nothing but my time, and even if it doesn't turn out good, what I'll have learned from the mere act of doing so is worth more than my time.
While filling out my online brewlog, I made a note about the 3 month timeframe and how 'clean' it looked inside the fermentation bucket about 'guess I'm santitizing and cleaning well'.
