Not long ago, Gonzo White <firstname.lastname@example.org> asked:

Yup, that's EXACTLY what they are talking about. If you look at dog food,
and several other food products, you'll find mention of ash.
Ash is what's left over after the product is burned under controlled
While some people aren't fond of ash, it is a measure of minerals. This is
very important to the taste of bread, especially sourdough breads. How
important? Well, the German flour rating system is strictly a measure of
the ash content of the flour. Higher ash flours are more whole grain
flours. Flours with more taste. And more nutrition.
There are many differences in flours, and that is one of them. An
important one, but just one. Look at the Artisan's treatise on flours and
their test of flours (http://www.theartisan.net/Flour_Suite_Frameset.htm
and http://www.theartisan.net/bredfrm.htm), or look at my own home page for
a test of different flours with sourdough breads
