First off I start with white wheat berries, I intend to try spelt, and emmer in the future. I don't measure exact amounts when sprouting I just roughly fill each 1/2 gallon mason jar to the 2 pints line. Then I fill each jar to rinse off the grain a few times. I use the handy green sprouting lid so I don't lose any grain when dumping out the water. I've also used cheesecloth and a rubber band, whatever works right? After the grain is rinsed, fill the jar with water and let it sit overnight 8+ hours. I usually go in the neighborhood of 12-15 hours soaking, it depends on when I fill the jar and when I remember to dump it out, it's a pretty forgiving process. The grain should've swelled to almost filling the jar, which is why I leave so much room at the top!
The next morning dump out the water and begin sprouting. It's exactly the same as all other sprouting at this point, rinse grain and keep it moist by rinsing twice a day am/pm. Until it sprouts tiny tails like above right.
Now comes the drying part. I layer the grain into 2 electric dehydrators using the fruit leather trays so the grain doesn't just fall through. Then I plug in and dry it all day. One of my dehydrators is faster so I just monitor it. You could also build one of these to avoid the electricity, which I do intend to build now... a pellet stove dehydrator. The grain should feel just as it did before sprouting, meaning it can't be crushed by a fingernail and it looks similar to this.
To grind it I use either my country living grain mill or my vitamix dry blender. I know the country living grain mill can grind it to the powdered flour consistency I'd need for bread, but it's really difficult. But grinding it to a "cornmeal" feel is rather easy (and a good arm work out). To get it the rest of the way I'll use the vitamix. But for this demo I use the blender the whole way because picture taking is just easier that way.
Before I grind I put the grain in the freezer, this keeps it from over heating during milling and having the oils go rancid. The risk is low for only grinding for a short time. In the blender it takes just over 1 minute to grind 2 cups of grain into flour. But I'd rather be safe than sorry.
Here's some links for more sprouting info. GNOWFGLINS and sprouted bread wiki style.
Now go make some bread! Any leftover flour I freeze, because flour with the bran inside it, like this has, will go bad much faster. Plus it's not "fortified" with anything to keep it's shelf life. So leftover flour --> freezer!
