Optimizing Flavor Extraction in Cocktails Through Sous Vide

Quick Definition: What It Is

A Roner is an immersion circulator used to hold a water bath at an exact temperature for sous vide work. In cocktail bars, it is often used to create controlled infusions, syrups, and flavor extractions with repeatable results.

Sous vide, a French term commonly translated as “under vacuum,” refers to sealing ingredients in a bag or jar and using a temperature controlled water bath to cook or infuse evenly at relatively low temperatures.

Why It Matters (for bartenders and drinkers)

For bartenders, sous vide turns “infusion” from a vague prep into a spec. Temperature and time become controllable variables, which improves consistency and reduces batch-to-batch drift.

For drinkers, the payoff is clearer flavor intent: brighter aromatics when that is the goal, cleaner spice extraction when warmth is desired, and a more consistent experience across repeat orders.
