Wine: basically fancy aged grape juice. Typically bought in bottles. Sometimes found in jugs. Occasionally purchased in cans, plastic bladder–equipped boxes, and Tetra Paks.
Now: pumped like gasoline from 500- and 1,000-liter mechanical kegs that are basically self-service wine-dispensing gas stations. Available now in France (mais oui!), soon at a grocery store near you? Perhaps if you’re very, very fortunate—the wine is très cheap and apparently not actually terrible. No word yet on whether it is acceptable to pump the wine directly into one’s mouth, presumably to be chased by “free samples” of figs, candy, and other bulk dry goods.
