So about 4.5 weeks ago I made a Chimay Grand Reserve PM and kind of messed up, but didn't realize it until last night. I checked the SG and it finished out at about 1.03 which seemed really high, but I went ahead and kegged it anyway figuring I could secondary in there if needed. Once I finished kegging I realized that I must have underfilled the primary (I primaried in my unmarked glass carboy for the first time) by a fair amount because I was about 1/2 gallon shy in my keg.
I put the recipe from the kit into BTP to guess my SG (yeah, basically I half assed this brew because I was in a hurry and now am paying for it) and I am guessing that based on my typical efficiency and the estimated reduced volume I was at about 1.101 SG. That puts me at about 9.5% abv and 70% apparent attenuation.
The sample tasted fine, so I am afraid of messing with it, but I don't want it to be so sweet that it isn't drinkable.
What would you guys do (except for going back to brew day and not being an idiot)?
