The word Kinnow rang a bell; I believe I tasted some back in the 1990's during a "citrus festival" held by a local grocery chain (Nature's Northwest, then owned by the current owners of New Season's Markets).

The Kinnows were only offered one year.

A very sought after "kid glove" (as opposed to slip skin) mandarin orange. Really very nice. I had assumed it was a newer variety

yep, I love them, I have 2 trees. they are tops on my list along with Daisy, which are much earlier. I start picking Daisy at thanksgiving. When they are all gone I start picking Kinnow, which will last past Easter here, longer in cooler areas.
