Unlike wine, which comes 12 bottles to a standard case, champagne is sold six bottles to a case. It is possible to buy champagne in quantities of 12 bottles at a time. A 12-bottle case of champagne is referred to by vendors and retailers as a crate.
There are purportedly more than 49 million bubbles in one standard 750-milliliter bottle of champagne. There are approximately five glasses of champagne in each bottle, which means that there are almost 10 million bubbles in a single glass of champagne. Higher-end champagnes have even more bubbles, with premium champagnes having as many as 250 million bubbles per bottle.
