I love the idea that wheat berries store for years.
Do you have to mix varieties to get good bread flour?
No, just use the straight hard white wheat.
The soft white wheat is not so good for bread. So make sure if you buy any, that it’s the hard.
A word of advice.
Your digestive system will not be used to it. As addictive as the bread is, you need to start slow with it and be aware than it’s high in roughage and can speed things up. It’s good for what ails you.
We gave a loaf to a friend and they loved it. The husband had a couple slices and it hit while they were driving home from somewhere. He barely made it home.
