I BIAB and normally get about 65% efficiency or less at times as far down as 58%. My usual method is to drain the bag over the kettle then a dunk sparge and then let the bag continue to drain in a two 20l bucket in a bucket setup. As things drain I just keep putting the runnings into the kettle. Anyway on Friday night for some reason the bag just didn't seem to be draining properly so after the dunk sparge I tipped the mash out of the bag and straight into the two bucket setup. I recirculated the resultant runnings through the mash slowly by hand, probably about 5 litres. I then boiled, hopped and did everything as normal. Well bugger me when I checked my OG and efficiency I got 77%. Any ideas on why the big improvement?
