dme to grain conversion

08-02-2010, 05:20 AM

ive got a great partial mash pale ale that i want to convert to an all grain beer.

what i need is a conversion for:

3 lbs light DME
and
3 lbs extra light DME.

as usual, any suggestions are appreciated

Slainte!!

the rule of thumb I always use is 1 lb of DME = 1.67 lb of grain

I would just sub in the equivalent weight of pale malt, so 6lbs DME = 10lbs Pale malt

thanks. to keep the color close, im thinking about 5.01lbs 2 row to sub the extra light dme and 5.01 lbs vienna to sub the light dme.

Assuming the DME contributes about 43 point-gal/lb, and the grain is 37 point-gal/lb (since you'd always be replacing extract with base malt), it would be:

1 lb DME = 43/(37*E) lb malt, where E is the efficiency. At 75% efficiency, that's 1.55 lb.

good point...I just always assume 70% efficiency, which gets you 1.67lbs. If you know your brewhouse efficiency, obviously use that # instead.

As for which grains to use...color is only one consideration. Unless you know what grains went into the DME (which often you don't ), it will be hard to match. Using Vienna for color is fine, but it will likely give you a different flavor than the DME - I doubt the DME used Vienna (though I really have no idea)
