Potential SG of MCI Grain in BeerSmith

[Garry]

I want to add the MCI grains to BeerSmith. In BeerSmith the grains have a field titled "Potential" which appears to have a gravity figure. Can anyone tell me how to calculate the potential of MCI's ale malt for example?

MCI's Ale malt spec sheet is here.

wats friability > 92%? on the spec sheet...is that diastatic power?

Where's biertourist when you need him?

I think you probably need to look at the extract:

100% extract is sugar -> 45 ppg or 375 per kg per litre
80% is typical for base malts 45 x 80% = 36 ppg or 303 per kg per litre
=>82% is 37 ppg or 307.5 in decimal.

That sounds right mr happy. If I look at UK Pale Malt in BeerSmith it's potential SG = 1.036.

So MCI's malts (all have an extract value of 82%) have a potential SG of 1.037.

Strictly you should take the moisture into account as well -> 37 x (1 - 4%) = 35.52 which is close enough to 36.

Apparently (according to New Brewing Lager) Friability is a measure of diastatic power - although not a very precise one - anything over 85% is good for infusion mashing. The SNR of 38 also indicates it should be good for infusion mashing: which you would kind of expect given that it's an ale malt.
