It's a bit old school to order a your cocktail "wet." But for those of you who want to know: most cocktails are a mix of wet and dry ingredients. Wet ingredients are the sweet liquids (liqueurs); dry ingredients are the savory or neutral spirits (liquors). If you want a wet martini, you want the recipe to favor more Sweet Vermouth and less gin (or vodka).
