Sangria blanca - equivalent to a fortified wine, but it's light and fruity. Great for summer parties.
2 limes
1/2 grapefruit
2 peaches
~1/2 liter Peach shnapps and/or triple sec
~1/2 liter Peach brandy
~2 bottles white wine - either one or both should be fairly good stuff, preferably with butter, fruit, and floral notes (or whatever tickles your fancy). Good sangria depends on good wine. That being said, I do use table wine (Carlos Rossi, eat your heart out) as filler after I've gotten the base down.
Optional - pint of seltzer to water it down
It's important to play with the fruit. You want some peach, and definitely some citrus, but other than that, who cares? Have fun with it. I think one version had orange instead of grapefruit, and another had apple, and one had mint leaves.
Anyway, each fruit should have a portion of it crushed and juiced and poured into the mix, and a portion of it diced or sliced. Once everything's in the gallon/gallon and a half container, it needs to be mixed. Hard. Shake the container, mash the contents with a wooden spoon, and shake some more.
Keep cold and let guests choose between getting a version with chunks or without.
