I've googled it and you get mixed responses from people. Some love it and some hate it. I am wondering if I might have had some without knowing it was actually black rice. The last bag of wild rice had black grained rice in it abit like a Pilau with the odd few red grains in it. If that is anything to go by, I won't by locating any.
From what I have read so far, it has a nutty, earthy flavour. Nutty I like, earthy I do not.
