The term “on the rocks” essentially means “on ice”. Serving your cocktail in a glass with ice keeps the drink chilled and dilutes it slightly as it melts. 

If you’re new to ordering drinks, here’s a key phrase crash course: 

  • “On the rocks” is a drink served over ice.
  • “Neat” or “Straight” refers to a spirit served alone, without any mixer or ice, in a glass at room temperature.
  • “Up” means mixed or shaken with ice and strained into a glass so the finished drink has no ice in it.

Tips for making cocktails on the rocks

Here are a few tips to keep in mind when serving drinks or cocktails on the rocks:

  1. Don’t let the drink sit too long. The longer you let an on the rocks drink sit, the more diluted it will get, and this affects the quality and flavors of the cocktail.
  2. Choose your spirits carefully. It all comes down to personal preference, but not all spirits are suitable for on the rocks. For example, high-end single malt scotch whiskeys are best enjoyed neat. However, some drinks are dependent on ice, such as frozen margaritas served with crushed ice.
  3. Know the classics. An old fashioned or Tom Collins is always served on the rocks. And you shouldn’t stray from this practice unless the drinker requests it specifically. 
  4. Use the right type of ice for your drink. Whiskey stones cool the drink without diluting and compromising the taste. Specialty ice slows down the speed of melting, especially ice balls.
  5. Serve on the rocks cocktails in the right glassware. A rocks glass is for neat spirits or on the rocks drinks like old fashioneds and negronis. Taller highball glasses should be used for cocktails containing mixers such as mojitos, cosmopolitans, and margaritas. 
  6. Learn the phrase “with a twist.” If someone asks for a drink “with a twist,” this comes from the zest or rind of citrus fruit, often hung on the glass as a garnish. 
  7. Use distilled or filtered water when making your ice cubesFreeze away from food with strong odors that could taint your ice.
