Dandelion is one of my best white wines! I have a couple of bottles from 2007 that I want to drink this summer. You don't always have to pick off every little bit of green, but I do because I think it imparts some bitterness that I find unpleasant.
I've heard that dandelion wine tastes "like liquid sunshine". I'll agree- it's fruity and bright and very much like a pinot grigio. It has hints of different fruits, with a citrusy crispness that is very nice. I prefer it just slightly off-dry, at about 1.000. Since it finished about .990, I simply stabilize and sweeten just enough to make it not so dry.
