I have a Harpoon IPA clone recipe that I have had repeated success with but it's an extract recipe and I'm trying ag more often than not. The recipe is "partial grain" calling for 8oz 60L crystal, 4oz 2-row pale, and 1 0z roasted barley for steeping. Then 4lb pale malt syrup and 4lb light DME. I don't know of any exact formula for conversion to all grain. Thanks for any help.
