A mixing glass is a thick-walled glass pitcher — typically 16 to 24 oz — used for stirring spirit-forward cocktails with ice before straining into the serving glass. The weight and mass of the glass help it stay cold during stirring, and the smooth interior makes it easy to rotate a bar spoon along the walls in a fluid, uninterrupted motion. Most mixing glasses have a pour spout for clean transfer to the serving glass. The Yarai pattern (a crosshatch of diagonal lines on the glass exterior) is the most recognized style and offers a secure grip when the glass is cold and wet.
Why It Matters
You can stir a Martini in a tall glass or a pint glass, but a proper mixing glass makes the technique easier and more controlled. The mass keeps the temperature down. The shape allows the bar spoon to rotate efficiently. It's the right tool for the job.
Where You'll Use It
Every stirred cocktail: Martinis, Negronis, Manhattans, Old Fashioneds, Rob Roys, and any spirit-forward combination that doesn't involve citrus.
