What does a "dry" martini refer to?

A "dry" martini refers specifically to the use of less vermouth in the drink compared to a "wet" martini, which contains a higher proportion of vermouth. The term “dry” denotes a preference for a more spirit-forward drink, allowing the primary flavor of the gin or vodka to shine through more prominently.

In a traditional martini, gin or vodka is combined with vermouth. When a drink is described as "dry," it indicates that the bartender uses just a small amount of vermouth, or in some cases, none at all. This gives the martini a crisper, stronger flavor profile, appealing to those who favor a more robust spirit presence.

The other options relate to different aspects of a martini but do not define what makes it "dry." A martini without ice focuses on serving style rather than the ingredients, while a martini served with a twist is more about the garnish used. A martini served in a chilled glass also pertains to presentation rather than the dry or wet distinction regarding vermouth content.
