Dennis Bunner Departs as Chief Oenologist at Bollinger
Dennis Bunner has left his position as Chief Oenologist at Bollinger, marking a significant leadership change at one of Champagne's most prominent houses.
What happened
Dennis Bunner has departed from Bollinger, where he held the position of Chief Oenologist. The departure was confirmed on or around 8 May 2026, marking the end of his tenure at one of the Champagne appellation's most recognised houses.
Why it matters
The Chief Oenologist occupies a central role in any major Champagne house, bearing responsibility for the winemaking decisions that define a maison's character and consistency across its range. When such a figure departs, it inevitably raises questions about continuity of style and the strategic direction the house intends to pursue.
At a house of Bollinger's standing, the position carries particular weight. The Chief Oenologist shapes not only the technical execution of each vintage and non-vintage release, but also the longer-term philosophy that underpins how the house presents itself to the market. A change at this level is therefore of genuine consequence — both internally, as the team adapts, and externally, as trade and consumers consider what may follow.
Whether Bollinger moves swiftly to appoint a successor, or takes time to reassess its oenological leadership, the transition period itself will be watched closely by those with an interest in how the house evolves.
Context
Bollinger is a Champagne AOC house based in the Champagne region of France. It occupies a prominent position within the industry and is regarded as one of the appellation's significant producers. Leadership changes at houses of this profile are relatively infrequent and, when they do occur, tend to attract attention from across the trade.
The role of Chief Oenologist is distinct from that of a cellar master in some houses, though the responsibilities frequently overlap in the areas of blending, quality oversight, and the stewardship of house style. Bunner's departure leaves a notable vacancy at a level where institutional knowledge and creative continuity are both highly valued.
No further details regarding the circumstances of the departure, or any planned succession, have been confirmed at the time of publication.
