I need to get my grain bill to the brewery asap so i can brew a wheat on Monday for a buddy's party then end of the month. I gave one of my laptops to my neice, not thinking that all my software for brewing and recipes were on it. I need a a grain bill for 20 gallons of wheat, I typically go 50/50. Looking to hit around 1050 - 1055. Oh, and maybe some advice on how much hallertau to throw in to reach 15-20 ibu. Mainly bittering. Thanks!
