Mostly inexpensive domestic US plonk, even some things that I don't mind drinking or that even might be tasty. (That said, most "value" wines I drink are from France, Italy and Spain.)
I'm not the "right one" to really help people how to learn about wine in a more traditional sense, but I'm trying to help people understand that there can be a myriad of things in it other than the "usual suspects" that make you not feel so good afterward.
