Review of Natural Blood Orange Flavor-FW:

Blood Orange is a very good when you want orange flavor but not that familiar flavor everyone knows and likes.
I don't have any "normal" orange flavors to really compare the difference, so I could be missing out, like when I finally caved in and bought Strawberry (also FW), which turned out to be a really nice flavor.

I like adding Blood Orange to tropical flavor mixes for an added twist.
I don't use stand alone flavors, so I don't know if this would be good as a single flavor, but as a mixer it is really good.
