Kalimotxo. It’s red wine and cola in roughly equal parts, to taste. It’s a great way to salvage old wine that’s a day or two past drinkable, especially on a hot day.
I described it once on reddit in the before times, and someone called it a “shit red wine spritzer” and I think that’s kinda apt.
The kalimotxo is actually pretty tame; half as potent as wine, so comparable to maybe a pale ale.
Can’t speak for that other madness though.
