Default Golden Promise...What Gives?

I know that the diastatic power over most brewers grain is quite variable, but when I have tried to calculate my mash efficiency, the data on Golden Promise runs from 120L to as low as 50L from some supplier sites. Does anyone know what the "real" DP for GP should be?

There's no "real" value, it will depend on everything from how it's malted to which farm it was grown on and how much rain that farm got last year. Refer to the spec sheet for the lot analysis of the particular batch you have.

Correct me if I am wrong, but I am pretty sure diastatic power and lovibond are independent of each other...

Yeah, but there's no conveniently different abbreviation for degrees Lintner. Unless you can come up with one.

Thanks for the reply. Midwest Supplies has the DP at 56L but the default in BeerSmith is 120L I just reset the BS number and will mash on Saturday. I have never run Golden Promise as high as 85% so we will see if I hit my numbers.

I've been meaning to try some GP someday. Just wondering what you're using for the remainder of the base malt? And what kinda beer are you brewing?

I used to be skeptical of the "Cadillac" base malts, but they make a big difference in flavor. I have Simpsons GP, and it provides an intense graham-cracker maltiness. You can use it in large amounts in beers where you'd like that flavor (browns, milds, most UK/US beer styles), or in small amounts and treat it like a specialty grain.

I am using GP for 85% with the balance of several caramels, blackprinz, melanoidin, and a touch of Marris just because I had a few lbs. Going to be yet another Strong Scotch with an OG target of 1110. Oak and bourbon going in this one for a 6 month sleep. God I'm running out of places to store this. Guess I will have to double my efforts to make room

85% will be more than enough.
