1 unit grains = .75 LME = .6 DME
13.25 lb pale = 9.9375 lb LME = 7.95 lb DME
Briess LME cans are 3.3 lbs. Therefore, 3 cans, theoretically needing 1 oz pale grain, rounding up to the ounce.

DromJohn - Thanks for the reply. I read the same online regarding the .75 multiplier I just wasn't sure what impacts there would be going from grain to extract e.g. if I should be adjusting steeping grains or hops.

 

[tyhoward]

Can anyone comment on the hop additions? It says 90 minute boil so the first addition is 30 minutes in? Just want to make sure I am understanding this correctly.

 

[DromJohn]

Yes, 60 minutes means from end of boil, therefore in your case 30 minutes from the start of the boil.

DromJohn - Continue to appreciate your input. Hopefully last question. This calls for an infusion mash. I was only planning to steep the grains. Is the 60 minute time still applicable? Thanks.

Sorry for the delay.
Yes the 60 minutes apply.

a tad late but that recipe comes straight from founders, this may help. its has a portion about swapping out a bunch of the grains for LME.
