I know this doesn't matter all that much, but do we have the specs for the different grains we have access to?  I'm trying to get a more accurate idea of my efficiency.

On the weekend I brewed a 5 gallon batch of a Stone Ruination Clone, and I copied the recipe I had found on HBT into BeerSmith.  The OG, colour, etc all matched what the recipe stated based on my normal efficiency.

When I brewed the batch, I got a higher OG than I expected.  I was happy because I thought my efficiency went up with the use of the new Barley Crusher (by about 7%).  Then I got to thinking that I'm not using exactly the same ingredients as are in BeerSmith (There is no Canadian 2-row for example).  I'm wondering if this may have something to do with the efficiency (It's the first batch I brewed with grain I got from the club).

When I look in BeerTools (which does list Canadian 2-row as well as American 2-row), I notice that American and Canadian 2-row contribute slightly differently to the OG.  I'm sure this is the case with other malts as well.

As for specific gravity points yield from each grain, I don't know if we have that on hand, but JohnQ can probably provide more information

Using the beertools software, you can select the specific grain and it will do the calculation for you.

I know, but BeerTools doesn't have Munton's grains.  So, I don't have a way of knowing exactly what each grain will contribute.

I think Richard might actually be the guy on this one, I heard him discussing that at Pic's on Saturday.

Didn't you say you have BeerSmith?
That's all in there.

I just google for the spec sheets (string: producer name grain name spec filetype:pdf) - what we were saying at Pics on Saturday is that there is variation in the grain from batch to batch, so the spec sheets are always wrong anyway. From what Esty was saying it seems like the error can be fairly significant, e.g. ~10%.

Ok.  Good enough then.

Thanks
