Dear Dr. Vinny,

Does the size of a wine bottle have any effect on the way wine ages? And why don't all wines come in big size bottles?

—Fernando V., Cartagena, Colombia

Dear Fernando,

Bigger bottles tend to age more slowly than smaller bottles, supposedly since the relative amount of oxygen trapped inside isn't as great. One theory is that the 750ml bottle became the standard because that size represents the lung capacity of a glassblower. Most people have gotten used to this size (I find it the perfect amount for two people to share), and since most wines are consumed shortly after being released, the need for the slow-aging, harder to handle, larger-format bottles is uncommon.
