Normally I leave my beer in a primary for 7-10 days and then ferment in a secondary for about 2-weeks. This last batch, due to multiple issues at home, stayed in a primary for 21 days (a this point I couldn't bottle still but didn't want to let it just sit on all the sludge at the bottom of the primary) so I transferred it to a secondary where it sat for over 3 weeks.
I bottled like I normally do (judging from what I saw in the siphon tube, it was the clearest beer I'd ever bottled) and had my first taste at 3 weeks. It's flat and sweet, similar to what beers taste like when I try the stuff left over in the bottling bucket. No foam when I pour. It doesn't appear to have carbonated at all.
My final gravity when I bottled as 1.013. I took a gravity sample from the bottle and it was 1.023.
So my question is, other than the obvious stuff (maybe I measured my priming sugar wrong, etc.) what could have caused this and/or could this be a result of the extra long fermentation?
Thanks,
