| Type: | drinkware |
A collins glass is a glass tumbler which typically contains 300ml410ml.[1] It is commonly used to serve sparkling cocktails, especially long drinks like the Tom Collins or John Collins. Its cylindrical shape, narrower and taller than a highball glass, keeps the drink carbonated longer by reducing the surface area of the drink.[2] It is a recommended glass for serving an espresso and tonic in.[3]
