So I brewed my interpretation on this yesterday. Used 11 pounds instead of 13.5, couldn't find dark candi sugar so I had to go with clear. Caramelized the first .75 runnings. Ended up with 1.072 gravity and 5.8 gallons into the fermenter. I must have done something wrong as the hydro sample tasted a bit bitter... Perhaps I burnt the first running, although the caramel it created didn't have this taste, I boiled for nearly 90 minutes. I was careful of the mash temperatures but perhaps I somehow released tannins from the grain, I don't 'know.. It's fermenting as I write this so I'll give it a chance to do its thing and we'll see what comes out.. Anybody else have this problem?
