I have about half a dozen AG brews under my belt now, all of which are bitters/pale ales. Although they are all ok, the common theme seems to be that they are too bitter for design, even when I deliberately reduced the hops schedule over the last couple of beers.
I think the problem may lie in the fact that the actual mash efficiency recorded in all beers is over 95%. I am guessing that these figures are wrong and that I am extracting less sugars from the malt than the efficiency suggests and therefore the hop additions are relatively too high.
I have a fully pumped 70 ltr brewery with a HERMS and a rotating sparge arm, which I built from scratch, so I expect the mash efficiency to be reasonable. the overall brewery efficiency may be some what less as the outlet from the boiler is a little high causing losses, the plate chiller and pipe work also cause waste.
My questions are - Am I barking up the wrong tree with this theory? Also how can I check or adjust the mash efficiency?
Thanks for any Help
