Your post made me look up triticale.
I have not seen it on sale here in Germany although a short google search shows me that it is grown here, especially in the lower mountain ranges. The article said that bad soil is better suited for rye and good soil for wheat, but still triticale has some advantages over either of them, e.g. a high protein content and no need for ploughing the soil.
Apparenty here in Germany it is added to baked goods, but the most part is used as animal fodder and for
energy production in biogas plants.
What is the taste of triticale?
