Happiness is whole kernel rye breads by Mestemacher in Germany, available in the United States

 I found these at my local health food store in Michigan, and they are delicious.

 

Happiness is the rye, and the straw thereof

In champion countrie a pleasure they take

To mow up their haume, for to brew and to bake:

The haume is the straw of the wheat or the rie

Which once being reaped, they mow by and by.
