I am drinking boxed white wine out of a coffee mug. I get a box, always, because I can't finish a bottle in one sitting (rather, I shouldn't and the Mr. doesn't really drink wine). I found this brand on sale at my local grocery store for $9 - yes $9. I've never had it before but it just tastes like standard, not-offensive wine.
The coffee mug is because I can no longer have wine glasses near my computer. I thought it was amusing because it says "coffee" on it. Fun fact: if you have shitty wine that you don't really *need* a glass for, the mug temperature controls it much better than a stupid wine glass. Plus, when you are half-blind, it's much easier to see for depth-perception related issues.
