I was trying to come up with a duvel clone, and I tried two ways of going about it. First, I tried 28 lbs of pils malt for a 10 gallon batch... 12 gallons before the 90 minute boil. BTP was claiming an OG of 1.073 and a FG of 1.018. That seems a little bit high for pils malt and Wyeast 1388 (belgian strong ale). I figured that I could decrease the FG by making light candi sugar total about twenty percent of my fermentables (17.9% to be exact). This yielded an OG of 1.082, which is nice, but the FG shot up to 1.020.
This seems to be a bit strange... I would expect this brew to attenuate down to 1.015 or somewhere around there. Wouldn't the candi sugar ferment completely?
Terminal gravity calculation a bit high?
Re: Terminal gravity calculation a bit high?
If you think the terminal gravity is high then increase the apparent attenuation. Belgian ales often have high apparent attenuations because of the candi sugar.Steve973 wrote:I was trying to come up with a duvel clone, and I tried two ways of going about it.
