On the rocks
German: On the Rocks Also known as: Auf Eis, Mit Eis
A serving style in which a drink is presented over ice cubes in the glass, usually a tumbler.
On the rocks means a drink is served over ice cubes, typically in a low, wide glass called a tumbler. The ice chills and dilutes slowly, which can make whisky, rum or liqueur milder and more approachable. The larger and clearer the pieces of ice, the more slowly they melt.
The alternatives are neat (no ice, room temperature) and straight up (chilled, no ice). Anyone ordering a drink on the rocks should know that meltwater will reduce its intensity somewhat over time.
