One of the most recognizable types of glassware is the Martini glass. It is a pop culture icon (thanks again, Mr. Bond), and its contents are unmistakable. Martini glasses have a long stem so that you can hold your glass without warming the cocktail itself. The wide mouth of the glass slopes outward, allowing for air to touch as much of the alcohol as possible to open up the spirit. The slope also provides a gentle rest for the iconic garnish on a cocktail pick.
