Plum Wine

I just went out for sushi and ordered a glass of plum wine. (I'm all about trying new things these days. My philosophy: Every day a different buzz.) It was good, in a check-that-off-the-list kinda way. It tastes like 100% juice (not from concentrate) that maybe sat out a little too long. Sweet and thick, with a kick!

I looked to the internet to tell me a bit more about plum wine, but mostly I found recipes on how to make it. Here is the first step from About.com's recipe:

1. Wash green ume plum and remove the calyxes with a bamboo stick.

Wash what and remove what with what? I'll leave that to the experts, and drink mine from the bottle.
