What Bottle hold 3 liters of champagne?

There isn't a standard bottle size for champagne that holds exactly 3 liters. Here's why:

* Standard Champagne Bottles: The most common champagne bottle size is the "standard" bottle which holds 750ml (0.75 liters).

* Magnum: A "Magnum" bottle holds 1.5 liters (twice the size of a standard bottle).

* Jeroboam: A "Jeroboam" bottle holds 3 liters (four times the size of a standard bottle).

So, a Jeroboam bottle is the champagne bottle that holds 3 liters.
