I have a Flanders Red that has been in the fermenter for about 8 months now (first yeast cake/pitch) and I plan on letting it go until April which will be a year. I checked it the other day and the sourness is nice, but the body is SUPER thin, like water. Is there anything I can do at this point to increase the body? I normally keg, but I plan on bottling my sour, and repitching on the cake. Should I brew a one gallon batch with a bunch of dextrine and add it to the fermenter or let it go? Any help will be appreciated.
