Spain uses elaborate receptacles, and mixes Coke with red wine
The Spanish are partial to sparkling wine, though not in the way you might imagine. Although they have their own version of a white grape frizzante, known as Cava, they are also known to forego CO2-ing the wine itself, and mixing in ‘gaseosa’ (soda) to a bottle of red. You can call this concoction “tinto de verano” or “kalimotxo,” depending on whether it uses a lemon-lime soda like Sprite or Fresca, or a cola-based soda, respectively.
Kalimotxo is a newer tradition, enjoyed predominantly in Basque country by the young and broke. It wouldn’t be out of the norm to find a group of teenagers drinking a mixture of cheap red wine and a 2 liter of Coca Cola out of a plastic bag.
A more typical way to serve the cocktail and other wines, would be out of a porron. A porron is essentially a glass booze bong, whose side spigot can be poured directly into your mouth. It is a point of pride to be able to hold the porron as far away as possible… or at least farther than the last guy. Other receptacles the Spanish enjoy their wine from are the botijo, an urn-like jug with one or more openings, and the bota de vino, a comma-shaped bladder usually made of leather.
“Tinto de Verano,” which translates to ‘Summer red wine,’ is relished by youths in the rest of the country, most frequently throughout the hottest months. It’s considered the poor man’s (or perhaps a more to-the-point) version of one of Spain’s most exported wine traditions -- sangria.
Despite what Pinterest would have you believe, Sangria was not invented by food bloggers with modern crystal punch sets. Sangria is a chilled red wine punch that includes chopped up fruit and brandy. Much like the laws protecting Champagne labeling, "true Sangria" is defined and protected under European Union law. Choose your words carefully, Pinners, or you might have the EU after you (you won't.)
