Q: What sizes of wine bottles does Coravin work on? Will Coravin work on magnums, double magnums, or even anything bigger?

A: Coravin systems are recommended to be used on any wine bottles that are standard magnum size or smaller, as long as they have a natural cork. Theoretically, a Coravin system could still be used on larger wine bottles, assuming a standard-sized neck and natural cork, but isn't recommended by Coravin.
