If you’ve ever sipped whiskey neat or on the rocks, you’ve likely used a rocks glass. But what is a rocks glass called? You’ll often hear it referred to as an “old fashioned glass,” “lowball glass,” or “whiskey glass.” Whether you’re enjoying a neat pour or mixing up a classic cocktail, this staple piece of barware is more versatile and interesting than you might think.
Discover what a rocks glass is
A rocks glass is a short, broad tumbler designed for spirits served neat or “on the rocks” (over ice). Thanks to its sturdy base and wide brim, you can comfortably muddle ingredients directly in the glass without worrying about tip-overs. Standard rocks glasses typically hold 6 to 10 ounces, while double old fashioned glasses (sometimes called DOF glasses) can handle up to 16 ounces to accommodate extra ingredients or large ice cubes.
Multiple names, one vessel
- Old fashioned glass: Named for the famous whiskey-based Old Fashioned cocktail, which involves muddling sugar, bitters, and fruit in the base of the glass.
- Whiskey glass or lowball: Perfect for those who prefer sipping spirits neat or with ice, and the lowball name highlights its short height.
- Rocks glass: Emphasizes that you’ll most often fill it with ice cubes (“rocks”) to keep your drink chilled.
Explore its origin story
The predecessor of the rocks glass can be traced back to the 17th and 18th centuries, when Scottish drinkers sipped from a shallow two-handled vessel known as a quaich. Over time, elaborate quaichs gave way to more practical glass tumblers, which were cheaper to produce and appealed to a wider audience. By the 19th century, these tumblers evolved into classic old fashioned glasses. Although many modern versions are pressed glass, some enthusiasts still appreciate the decorative, cut-glass style reminiscent of vintage designs.
Learn essential design traits
Rocks glasses stand out for their functional design, which heightens your drinking experience:
- Wide brim: Helps release fragrances from the spirit or cocktail.
- Thick base: Allows you to muddle solid ingredients, like sugar cubes or fruit, right in the glass.
- Short profile: Keeps the drink close to the rim, making it easier to swirl or stir without losing precious liquid.
- Versatile capacity: Holds just enough spirits (plus ice) for classic recipes or modern favorites.
Enjoy your rocks glass at home
You don’t have to be a whiskey connoisseur to appreciate the convenience and style of a rocks glass. It’s a great choice for many situations:
- Serving neat whiskey or bourbon, letting you concentrate on the aroma without too much distance between you and the spirit.
- Mixing Old Fashioneds, Negronis, or other cocktails that require muddling ingredients in the glass.
- Experimenting with ice shapes, like large cubes or spheres, which stay colder longer and dilute your drink more slowly.
- Creating an attractive home bar display by adding a set of matching rocks glasses with your favorite bottle of whiskey.
Take time to explore the different styles and designs available, from timeless cut glass to smooth modern silhouettes. Whichever option you pick, your rocks glass allows you to enjoy spirits in a way that’s practical, comfortable, and fun.
