Joe posted a good review of P-22 in Mango Reviews.
I tried it once at a tasting, and the sample I had was very simple. It had the flavor of Parsnips, and the texture of Cream. Very nice fruit.
As far as I am aware it's mono, and not released yet with no future plans, but who knows.
As far as Carla is concerned, I'm thankful for the opinions. Thick skin bodes well for shelf life, and if it is truly superior to 36-8, then I'm looking for some scions.
