Floor Malted is not the same. Its the technique used in the malting process. I generally prefer floor malted stuff, like Weyermann Floor Malted Bohemian Pils Malt or Warminster Maris Otter. It is fully modified IIRC.
Briess does make an undermodified Pils Malt but it is the only one I know of. Ive thought about getting some to see if decocting really makes a difference in flavor with undermodifed as opposed to using fully modified malt.
One interesting thing to note is that they don’t do a traditional triple decoction. There are no steps between 100 and 149 F, other than the ramp up of the decoction to boil.
The Kolbach is listed as 38. From Noonan: “Malts destined for infusion mashing should have an SNR of 36-42%,. . . For traditional lager malts, 30-33% indicates undermodification, and 37-40% indicates overmodification.”
I was hoping to find some of the “traditional lager malts” he’s talking about, in the 34-36% range, but I don’t think those exist anymore.
What are you trying to achieve with the lower diastatic power? You might be able to lower the overall conversion potential of the mash by adding some Munich, Vienna or light toasted malt.
4swan - The Briess “undermodified” malt still has a Kolbach index of 37, which is “overmodified” by traditional lager malt standards. It’s less modified than most malt, but still more modified than I was hoping to find.
Thomas - Low DP is not the reason I’m trying to find poorly modified malt. There are low-DP, highly modified malts, like some British pale malts. I’m looking for malt with a low soluble nitrogen ratio, suitable for traditional decoction mashing.
A year or two ago I came across the website for some guy who made his own countertop “floor” malting system. It looked really sweet. Any idea where I can buy raw Bohemian barley?
I can get raw 6-row at the Mennonite store down the road, but I don’t know how good that’ll be for what I’m trying to do.
I will let you know if I find any. I know it’s possible to get regular north american 2 row. There is a place in Reno NV called Rebel malting and he will sell you unmalted harrington barley by the sack. If you want a specific heirloom cultivar that’s going to be trickier. I have been searching for heirloom cultivars for a while now and have not found any really solid leads. The north american barley growing scene is very much bleeding edge oriented as it is still very much a commodity crop and the small indi farmers have not paid attention to it much yet. Consider it on my list of varieties to find.
Morti- Colorado Malting Company sells unmalted 2-row barley too, not sure what they kind they grow. I’m not really sure if I’m up for growing my own. I mean, I have a field and a tractor, but I wouldn’t know where to start.
wow, a field and a tractor is one tractor and about 3/4 of a field more than I have! For what it’s worth I think the main thing is not to much nitrogen and planting in the fall. It’s actually a really good winter cover crop, and if you return your waste to the fields a pretty good green manure.
I don’t think the field has been farmed since the 60s, maybe earlier. Right now it’s just full of grass. I’m not sure if I have a plow to hitch to the tractor.
Your location has a lot to do with whether it’s worth it to even try to grow barley (no, you can’t plant malt…malt is made from barley). Dan Listermann tried growing malt in Ohio and reportedly harvested about 10% as much as he planted!
