​ Since 1954, Rousseau has been the only “tonnelier/foudrier” in Burgundy, both a tank/cask builder and a barrel maker. The passion for crafting large format vessels remains today as the third generation coopers run both barrels and tanks/casks “ateliers” (workshops).

Fermentation & Maturation Vessels

Open-Top Fermentation Tanks

These traditional open fermenters blend time-honored techniques with modern winemaking practices. Open-top designs are ideal for red wine fermentation, allowing greater control over cap management and extraction. These tanks help develop deeper color, fuller body, and enhanced aromatic expression.

For added functionality, they can be equipped with accessories such as stainless steel valves, cooling panels, sample ports, or thermometers to suit your specific vinification needs.

Closed-Top Fermentation & Maturation Tanks

Featuring wide lids (up to 55" in diameter) or fully removable tops, these tanks are versatile enough for both fermentation and aging. Their sealed design supports a more controlled environment during vinification, while still offering easy access for cleaning and inspection.

Over time, the oak structure of these tanks imparts gentle tannins and added mouthfeel, enhancing the natural texture and fruit purity of the wine. Suitable for both red and white varietals, they are a preferred choice for winemakers aiming to balance tradition with precision.

Round & Oval Maturation Casks

Ideal for long-term aging, round and oval casks emphasize finesse and elegance over aggressive oak character. Their size and shape create a gentle micro-oxygenation process that enhances wine stability and aromatic integration. Oval casks are also more space-efficient—an excellent solution for wineries with limited cellar room.

These casks can last 10 to 20 years, significantly reducing costs compared to standard barrels, which require replacement every 3 to 5 years. Optional fittings include cooling panels, stainless or hydraulic bungs, valves, sample ports, and integrated thermometers.

The larger format helps produce rounder, more fruit-driven wines that can be bottled earlier without sacrificing quality.
