So I'm just trying to figure out what happened here...
For my 5th brew, I made a PM version of BierMuncher's Black Pearl Porter. I used this
recipe. Hit my mash temps fine, everything looked good. OG was 1.054, which was a little lower than expected, but good enough for now.
This was exactly one month ago. Tonight I bottled it, and when I measured my FG, it was 1.028.
I did pitch at a pretty low temp, about 58 degrees. I really shook the hell out of the fermenter (bucket), so before I pitched there was a nice layer of foam/bubbles on top of the wort. I used S-04, and while I've always rehydrated in the past, I thought I'd throw caution to the wind here and just sprinkle on top. It took a long time for fermentation to start, almost 72 hours, but once it got going it seemed to ferment normally (based on airlock bubbling, which I know isn't really a good indication of anything - my point is only that airlock activity was pretty much the same as it's been for all my previous beers).
Anyone have any idea why the attenuation would have been so minimal? Hydro sample tasted good, so it looks like I'm going to have a nice tasting session porter, but still ... not sure what happened or what I could have done differently to avoid this problem.
Thanks in advance for any help!
