Have you ever found yourself asking whats the best size for a rocks glass? Whether you’re new to whiskey cocktails or a seasoned enthusiast, choosing the right glass can make a big difference in your sipping experience. From the Old Fashioned glass to the larger, more versatile rocks glass, here’s how to pick the perfect size for your home bar.
Know the main differences
Rocks glasses and Old Fashioned glasses look similar at first glance, but their sizes and uses can vary.
Old Fashioned vs rocks glass
- Old Fashioned glass: Typically between six and eight ounces, ideal for a two-ounce pour of whiskey plus ice.
- Rocks glass (or double Old Fashioned): Often seven ounces or larger, making it more versatile for drinks with more mixers or larger ice cubes.
Because the Old Fashioned glass is slightly smaller, it’s perfect for a focused whiskey sipping session or cocktails that don’t require much extra room. The rocks glass, meanwhile, is better if you like more substantial mixed drinks or want to accommodate big, slow-melting ice.
Pick the right capacity
When deciding how many ounces you need, think about your drink habits. If you prefer classic cocktails with fewer ingredients, glasses around six to eight ounces are plenty. On the other hand, if you like experimenting with specialty recipes or mixing in non-alcoholic ingredients, a larger glass—sometimes up to 10 ounces—could be more comfortable.
- 6–8 ounces: Great for neat pours, Old Fashioneds, or simple whiskey cocktails.
- 7–10 ounces: Perfect if you enjoy extra ice, citrus wedges, or a bit of soda.
Consider your cocktail style
Do you stick to a classic whiskey cocktail like an Old Fashioned or do you branch into other mixed drinks? Larger rocks glasses can handle everything from a straightforward Sazerac to a cocktail with multiple juices and syrups.
Versatility matters
- A bigger rocks glass can hold large-format ice cubes, a growing trend among cocktail enthusiasts.
- Some glasses, like the Yarai Rocks Glass, do double duty as a mixing glass, giving you even more flexibility.
Weigh design and function
A rocks glass usually has a thick base that feels comfortable in your hand and provides stability. This design also helps keep cocktails chilled if you’re muddling fruit or adding extra garnishes.
Quick tips for design
- Opt for a flat bottom and room for a large ice cube if you like a slow melt.
- Check if the sides are slightly flared or straight. Straighter sides maximize room for ice nuances, while flared edges can be more comfortable to sip from.
Settle on your best fit
Ultimately, deciding whats the best size for a rocks glass comes down to your personal preference and how you enjoy your cocktails at home. If you’re mostly sipping whiskey neat or making smaller Old Fashioneds, a glass in the six to eight-ounce range will do the job beautifully. If you prefer space to experiment with multiple ingredients or love a generous amount of ice, you might lean toward something larger.
As you explore different cocktails, take note of the glass size you’re comfortable with. Sometimes, having a few sizes handy allows you to switch things up without crowding your cabinet. Whichever glass you choose, feel free to personalize it with the design and functionality that suits your style. After all, the perfect rocks glass is the one that makes you savor each sip.
