I finally got to try a loaf of bread with the infamous purple flour that is available from SFBI. While visiting in Alberta last week I went to a farmer's market that sold "artisan" breads. One happened to be baked with a percentage of purple flour. The loaf was a very attractive shade of light purple while the flavor was mildly nutty. The highest percentage of the loaf was a white whole wheat. All in all it was very good.
When it comes to flavorful, however, the Red Fife has it beat in my opinion.
The irony of the whole taste test is that the purple flour is grown in the province next to me (Saskatchewan). The grower supplies one of the bigger distributors in Saskatchewan who in turn supplies SFBI. I tried to purchase from Saskatchewan but it is not available for sale for personal consumption in Canada. It is sold all over the world but not in Canada. I asked about the feasibility of purchasing from SFBI and shipping to Canada but SFBI cannot ship it across the border. That is apparently forboden - never mind the expense of shipping.
And that is how bureaucracy rules...
