Would like to take a shot at brewing an Old Ale and other HG brews but only have just under a 8 gallon kettle and I brew in a bag. I have some old "Ale Pale" buckets and was wondering if I could just do my normal mash, transfer 1st wort into an Ale Pale, do a new 2nd mash and just boil that down while continuously adding the 1st mash until I get to the volume I usually add my bittering hops. Would this work? How could I project my gravity?
