Question

What's the difference when you order a martini "dry" or not?

Answer 1

Well, everyone is right. So I order wet martinis. That's the way I like 'em!

Answer 2

a dry martini has little or no vermouth in it.

Answer 3

a dry martini has dry vermouth, a sweet martini has sweet vermouth,  a straight martini has none, & a perfect has both vermouths.

Answer 4

The amount of dry vermouth (vs sweet vermouth, used in other drinks) in a martini dictates the "dryness" of it, the less vermouth, the "drier" the martini.  

Oh, and just in case you have a question about a dirty martini - that would mean you want the olive juice (vs just the olive alone) poured into the drink along with the olive.

Answer 5

Dry means less vermouth. The vermouth adds a bit of sweetness. Don't over do it.
