Rocks Glasses
The rocks glass — also called an Old Fashioned glass or lowball — is the most versatile vessel in the home bar. Short, wide, and comfortable to hold, it's the right glass for spirit-forward drinks served on the rocks, for drinks with a single large ice cube, and for anything you want to feel substantial and grounded.
Why it earns its place
The wide mouth of a rocks glass lets you appreciate the aroma of a drink while also giving you a comfortable angle for sipping. The weight and low profile make it feel solid — which subtly communicates that the drink inside is serious. It's the glass that says "I made this with intention."
When I reach for it
Sazeracs, Old Fashioneds, Negronis, Whiskey Sours on the rocks, anything served with a single large cube.
Where people usually go wrong
Glasses so heavy they're uncomfortable. A well-weighted rocks glass should feel substantial but not like a weapon.
"I like to use a simple, uncut rocks glass because the clarity shows the drink and the large cube inside it."

Questions I hear a lot
What drinks belong in a rocks glass?
Spirit-forward AF Cocktails served on the rocks — Sazerac-style drinks, Old Fashioned variations, Negroni-style builds, and any drink you want served over a single large ice cube. A Whiskey Sour served on the rocks also belongs in a rocks glass. The low, wide profile communicates that the drink is substantial and meant to be sipped slowly.
What's the difference between a rocks glass and a highball glass?
A rocks glass is short and wide — designed for spirit-forward drinks on a single ice cube. A highball glass is tall and narrower — designed for built drinks over multiple ice cubes with a sparkling topper. They are not interchangeable: a Mojito in a rocks glass has no room for ice and sparkling water; a Sazerac in a highball looks wrong and the ice-to-drink ratio is off.
What should I look for when buying rocks glasses?
A 10-12 oz capacity, clear glass (not tinted or cut in a way that obscures the drink), a weight that feels substantial without being cumbersome, and a base wide enough that the glass doesn't tip. Avoid novelty or heavily cut crystal — it distracts from the drink. A set of four simple, clear rocks glasses handles most home situations.
