FAQ
What is the difference between a whiskey glass and a rocks glass?
A whiskey glass is a general term for any glass used to serve whiskey, while a rocks glass refers specifically to a short, wide glass with a thick base—perfect for whiskey served over ice (or “on the rocks”). So, all rocks glasses are whiskey glasses, but not all whiskey glasses are rocks glasses.
Is a rocks glass the same as a whiskey tumbler?
Yes, the terms are often used interchangeably. Both refer to a short, wide glass used for serving whiskey neat or over ice. However, “whiskey tumbler” may also refer to more modern or stemless styles with a rounder shape.
Which type of glass is best for drinking whiskey neat?
The Glencairn glass is widely considered the best for drinking whiskey neat. Its tulip shape helps concentrate aromas and enhances the tasting experience. For casual sipping, a rocks glass also works well.
Are rocks glasses good for whiskey cocktails?
Yes, rocks glasses are perfect for whiskey cocktails like the Old Fashioned, Whiskey Sour, or Negroni. Their wide mouth allows for muddling and ice, while the sturdy base supports stirring and presentation.
Can I customize whiskey glasses with my logo or name?
Absolutely. We offer several custom options including engraving, screen printing, UV full-color printing, and decal applications. You can add your company logo, event name, or even individual names to each glass.
What is the best whiskey glass for bourbon or Scotch?
For bourbon, a rocks glass or whiskey tumbler is a popular choice, especially for cocktails or sipping with ice.
For Scotch, the Glencairn glass is often preferred because it enhances the nose and flavor of neat pours.
Are rocks glasses dishwasher safe?
Yes, most rocks glasses made from high-quality glass are dishwasher safe. However, for glasses with printed logos or metallic details, handwashing is recommended to preserve the design.
Where can I buy branded rocks glasses in bulk?
You can purchase branded rocks glasses directly from glassware manufacturers like DM Glassware or through B2B platforms. We offer bulk pricing, custom branding, and fast turnaround for large orders.
What makes a whiskey glass different from a Glencairn glass?
A whiskey glass like a rocks glass is designed for versatility—used with or without ice. The Glencairn glass is specifically shaped for tasting, with a narrow mouth and curved body to enhance aroma and flavor. It’s ideal for neat pours and professional tastings.
Can you use a rocks glass for whiskey tasting?
Yes, you can use a rocks glass for casual whiskey tasting, especially for bourbon or blends. However, for detailed aroma and flavor analysis, the Glencairn glass or other tulip-shaped glasses offer a better sensory experience.
