These terms "whole wheat" and "whole grain" vary based upon local laws, but these are the general definitions…
- "Whole grain" flour contains the whole grain — all parts of the grain — milled as is. None of the bran, germ and endosperm have not been removed. With all the bran and germ, this whole grain flour has a greater fiber content and provides a deeper flavor to breads. When baking, if the whole grain is not milled finely enough, and if the bran in the flour is not hydrated enough, the bran may cause dough not to rise as well as another dough blended with a higher amount of "white" flour. All "whole grain" flours are also "whole wheat" flours.
- "Whole wheat" flour starts with the whole grain but may have the bran and germ removed during milling and then has some (or most) of it reintroduced. Often the germ (which contains oil and can go rancid) is not reintroduced in order to make the flour more shelf-stable. Whole wheat flour in Canada may have up to 5% of the grain removed.
The indication of "white" or "red" color refers to the color of the bran (exterior layer) of the kernel. Red has a higher protein content than white.
The time of year (eg. "winter") refers to the time of year the wheat was harvested.
I'm a baker who makes 100% whole grain sourdough bread using this flour. Notice how many different ways that this flour is described on the page and on the packaging. 🙃
