I work a lot of fancy events as a caterer and often have a drink behind the scenes, but often these events are in random offices with no bar support, resulting in us drinking strange concoctions.

Spanish coke is popular, which is just red wine and coke. This is probably second only to white wine spritzers. Separately in day events, we've found putting espresso into coke over ice is surprisingly okay, I wouldn't say it's better than the sum of its parts, but probably on par with normal coke.

So I had the wise idea of shaking espresso, coke, and red wine together, just to see what it tasted like. I'd truly give it a 5/10. Which isn't bad if not for the fact that I'd give each ingredient alone a 6/10 or better.
