Made this beer twice, once as a PM and the second time as an AG. Hopefully I made the conversions correctly. The other change was to only boil for 60 min instead of 90 min. The bitterness dropped from 102 to 92.9 but still a little too bitter. If it makes any difference in knowing what to do next, I put a pinch or two of table sugar in the last glass I drank and it seemed to lessen the bitterness. Thanks with help from here, the mash efficiency went from 59% to 69%. Think I can hit 75% next time as I did on another beer I made. Any thoughts on what to do to make this beer less bitter but retain the chocolate / coffee flavor?
