Lees Stirring / Bâtonnage
What happens when a winemaker stirs the sediment beneath the wine? Follow the movement, the texture and the choice to leave well alone.

Lees, contact and movement
After fermentation, sediment settles beneath the wine. Fermentation lees include yeast cells and other fine material. A producer may retain selected fine lees during maturation. Bâtonnage is the deliberate movement that puts settled lees back into suspension; sur lie means that the wine spends time on its lees.
The choice connects to Aging on the Lees. Ask two separate questions: how long was the wine in contact with lees, and were those lees stirred? The answers help explain a production account without turning one term into a guarantee of taste.
A simple picture of the choice
Rest
Selected lees settle beneath the wine during maturation.
Resuspend
The cellar team stirs or otherwise moves the lees back into contact with the wine.
Observe
The maker follows the wine’s development and adjusts whether, when and how often to repeat the action.
Why a winemaker might choose it
Lees contact can influence texture and the integration of fruit, yeast-derived characters and oak when wood is involved. Stirring can increase those effects. Oxygen exposure also matters: the operation changes more than the position of sediment. The useful balance depends on the wine, the lees and the vessel.
The Australian Wine Research Institute describes both potential benefits and drawbacks. More movement is not automatically an improvement. A maker may reduce stirring or leave lees undisturbed when the desired freshness and texture are already developing.
A producer’s own account
Jordan’s 2011 explanation by winemaker Rob Davis describes stirring lees in Chardonnay barrels to shape mouthfeel. It also explains that the frequency varies with the vintage and warns that excessive stirring can obscure the fruit character the team wants. Treat that account as an example of intent, rather than a schedule for every Chardonnay.
Its barrel setting adds another question: what came from the wood, and what came from lees contact? Those influences can work together while remaining separate cellar decisions. Lees contact also occurs in steel, as the producer example in our Chasselas profile demonstrates.
Keep these terms separate
| Term | What to ask |
|---|---|
| Sur lie / on the lees | How long, on which lees and in what vessel? |
| Bâtonnage / lees stirring | Was the sediment deliberately resuspended, and why? |
| Malolactic fermentation | Was malic acid converted to lactic acid? This is a separate biological process. |
| Riddling | Was bottle sediment moved towards the neck before disgorgement in sparkling production? |
A small Cork Dork discovery
Give your curiosity a little room.
Read two white-wine producer notes. Record lees-contact time, whether stirring is mentioned, the vessel and the malolactic decision. An unstated detail stays unknown. If tasting, describe texture before deciding which cellar choice might explain it.
Your observations, your words. Small pours welcome.
A few questions worth uncorking.
Does sur lie mean the wine was stirred?
No. It establishes lees contact; stirring is an additional choice.
Does creamy texture prove bâtonnage?
No. Lees contact, malolactic choices, wood and other factors can contribute to texture.
Is riddling another name for bâtonnage?
No. Riddling directs sediment towards the bottle neck in traditional-method sparkling production.
