Paul, that recipe is sorely enticing, and I shall have to try it on one of those very rare occasions upon which I write a grocery list with an eye toward attempting and successfully completing a recipe. This one seems to more or less boil down to "leave shit sitting around; add ice", which even I am capable of handling. Probably.
Until then, I shall have to content myself with the boxed Sangria I bought yesterday, on a lark, at the supermarket. Yes, it exists; like the devil, it takes many forms, and presently one of them has manifested in a quite colorful, almost celebratory box on my kitchen counter. It really beats the whole this is Mexican theme down your throat with stylized pictures of sombreros and cacti and lawn mowers and such. "RED SANGRIA", declares the box in one of those freeware, proto-Taco Bell menu fonts. (White Sangria also exists - I don't know either)
I hadn't had sangria in a while, so I started off with a nice tall glass and it seemed pretty tasty. Tart and kicky; this is a flavor that could conceivably pull off a beret. In direct contrast to most cheap-n-potent drinks, this is actually less tolerable the further into your cups one gets. It got to the point where I said (inwardly) something along the lines of fuck this, I am going to get goddamned heartburn here but I am not leaving a perfectly good glass out for the ants. RED SANGRIA from the box was not tested for along-the-pecker performance by this reviewer.
It'll get you good and drunk, though. APPROVED
