Hey guys, I was wondering if someone could run something through beer smith for me. I made this extract once and it turned out pretty good. I want to try it all grain. I am overseas and away from beer smith right now but I need to place the order as soon as possible to be ready for my return.

9 lbs of DME
2 oz of Chinook @ 60 min
1 oz of Simcoe @ 30 min
1 oz of Northern Brewer @ 10 min
1 oz of Crystal @ flameout
2 oz of Citra for dryhop
High gravity yeast WLP 099 (I think)

Thanks everyone, Nick

1lb of base grain= .6 DME

So you need 15 lbs of base grain.
