Does DME Have Diastatic Power
|
|
Any help with this question would be very helpful. Does DME have diastatic power? In particular does Light DME or Wheat DME have the power to convert the starches of some specialty malts with DP of less than 35?

I'm guessing no, but I really don't know. How about using some 6-row?

No, it doesn't.
What specialty malts are you looking at using?

There exist malt extracts with diastatic power, but normally they do not and you would know if you had the exception.

Thank you all for the quick responses. I expected that it did not and you guys confirmed it.
I asked because I'm formulating recipies in my head for partial mash beers, and wanted to make sure that I don't screw them up before I even brew it. I was thinking of cutting out the high poundage of base malt and just mash the specialty stuff.

You want to mash before adding the DME anyway. Bring the wort from your partial mash up to a boil, then add your DME. Or even add it at the end of the boil. You only need enough base malt to get conversion, so it doesn't have to be that much in most recipes. The rest is replaced with extract.

Got'cha. Thanks, ChshreCat. But since that's the case, I might as well just go AG and forget this PM stuff. |

Yes. The only point of PM (IMO) is so you can use a smaller mashtun and do a partial boil.
