I followed my normal fermenting process with the Better Bottle in my fermentation chamber to control the temp. Went with the recommended 68° until fermentation started to slow (after the 4th day) then ramped it up to 70° and left it there for a total of 4 weeks. Normally that gets me into the 10.012 range with previous beers but this one is a higher gravity beer and it was from a LME kit.
I am thinking of dropping a bit of fresh yeast into the keg and raising my keezer temp up to a fermentation temp for a while but I'm not sure if this is a good idea. Any thoughts?
Sometimes beers make with lots of extract just don't attenuate that well, at least not as well as their AG counterparts. It just has to do with the lack of fermentability of the brand of extract and the amount. I assume there was a lot of extract in this batch to get an OG of 1.078, although I believe Pliny does have a pound of corn sugar in most versions of the recipe (which helps it attenuate better).
I've had plenty of extract beers stop permanently at 1.020, and they were just done. They still were fine, and Pliny has enough bitterness to it that you may not even notice much of a difference in flavor at all between 1.014 and 1.020 in the end.
