If you're a wine greenhorn, you gotta start like the rest of us did...Boone's Farm Strawberry Hill...
Just kidding, that stuff is nasty and is for teenagers...
A friend that worked in a wine shop used to bring me a certain bottle of merlot that was great. Unfortunately, I can't remember the name of it. He knows my wife likes sweet wine, so recommended Yellow Tail Shiraz. Since I don't drink very often, I haven't tried it yet.
Since being diagnosed as T2, the only alcohol I've had is Michelob's Ultra Amber. It's not bad for such a light beer. Does this also prevent DP?
