One of the teas in that I received in the Orchard Sampler Oolong pack from Adagio is a Grapefruit Oolong.

From the website this tea contains oolong tea, natural grapefruit flavor, orange peels and marigold flowers.

The Grapefruit Oolong is available in a sample size for $2, 2oz for $6 and 16oz for $29.

When I first opened the packet I would have sworn that someone near me cut into a fresh grapefruit.  All I could smell was that unmistakeable sour tang.  I could see pieces of peel and bits of marigold petals.  Once brewed it smelled a little sweeter, but still very much like grapefruit.  It tasted sweet, but also a little tart. I didn’t get much of the marigold, which I think is good given my dislike of flowery teas, but I got plenty of fresh tart grapefruit.  Again, I think this would make a nice iced tea in summertime, but I enjoyed it hot as well.
