Just hovering over a few recipies from TastyBrew, and I notice this site may well be American, and hence, so might be their gallons. So, I am in some dilemma. If the batch size is 5 gal according to tastybrew, and I presume its in UK gals, then the ingredients quantities will be matched for US gallons and it will all go pete tong. I genuinely don't know what to do. I suppose the only answer would be to recalculate and transfer everything over to UK measurements I guess?
