Beginning several days before you hope to be eating this bread, rinse the wheat berries in cool water, drain and submerge the berries with cool water in a large bowl. Cover the bowl with a plate or cloth, and allow the berries to soak at normal room temperature overnight or for about 12 hours. The berries will soak up a considerable amount of water. Drain the berries in a colander, cover the colander with a plate to prevent the berries from drying out, and set it in a place away from light and where the sun won't shine on it. Rinse the berries about 3 times a day, and they will soon begin to sprout.
Growth depends on moisture and temperature so be patient.
Grind in a food mill or in a food processor. After grinding, dump the mushed up grain onto a clean work surface. Squeeze and knead the grain for about 10 minutes, and then form up 2 small round, hearth-style loaves with your hands. Sprinkle an insulated cookie sheet with a little bran or cornmeal, and put the loaves on it. Preheating the oven is not necessary.
