High-volume concrete tanks: stability, purity and expression of the terroir in each production
At Sonoma by SAS, we have been perfecting the manufacture of concrete wine tanks for years that combine technical precision and oenological innovation. Although our ovoid vats are especially renowned for their unique geometry, our large volume tanks are an essential tool for wineries looking to vinify with stability, homogeneity and absolute respect for the character of the grape.
In a context in which quality requires a balance between tradition and technology, large-format concrete tanks have established themselves as a strategic choice for those who want to make wines with naturalness, thermal control and authentic expression of the terroir.
A noble material that enhances authenticity
Concrete is a neutral material, without aromatic input, which allows a soft and controlled micro-oxygenation thanks to its natural porosity. This micro-oxygenation—more subtle than that of wood—favours a progressive evolution of the wine, rounds tannins and adds volume without adding external notes. Wines made in high-volume concrete have a sharper fruit, greater varietal purity and a more balanced structure, respecting the essence of the vineyard.
Thermal inertia: an essential ally in large-scale fermentations
The thermal inertia of concrete offers a stable environment that reduces temperature fluctuations, especially relevant in bulky fermentations. This translates into:
- More controlled fermentations
- Reduced need for external interventions
- Significant energy savings
- Increased microbiological safety
Ideal for long processes, slow aging and processing where stability makes the difference.
The Sonoma by SAS range of high-volume tanks
At Sonoma by SAS, we offer a complete range of large-format tanks to suit the diversity of wineries’ technical needs. Among them is the 38hl SUPER EGG, valued for its thermal behaviour and its great homogeneity in wide fermentations; the 22 and 30hl SQUARE, designed for wineries looking for maximum stability, use of space and neutral and precise winemaking. Its square geometry makes it a very versatile option, ideal for both fermentation and ageing in concrete; the truncated conical design of the 31, 36 and 40hl CONICAL tanks are designed to offer optimal cap management, balanced fermentations and excellent integration of components in all types of wines, especially reds of intensity and structure; and the 54hl TOWER tanks, for wineries looking for thermal stability, homogeneity in large volumes and an authentic, balanced and precise expression of the wine. Its capacity makes it an ideal tank for extensive fermentations and ageing where consistency is key.
All these models are manufactured with high-density mass-pigmented concrete, with the possibility of customisation in all types of finishes to adapt to the reality of each winery.
Homogeneity and consistency in each preparation
Sonoma by SAS’s high-volume tanks ensure uniform wine behaviour throughout the process. Its smooth interior design and stable structure ensure:
- Better component integration
- Precise and clean aromas
- Rounder and more enveloping textures
- Harmonious and constant evolutions
An indispensable tool for wines looking for consistency, identity and quality sustained over time.
Durability and reliability: tanks for generations
Built with high-density concrete and advanced reinforcement techniques, our tanks stand out for their long service life and their resistance to cracks and wear. Maintenance is minimal thanks to smooth, easy-to-clean internal surfaces. Every deposit is a solid investment, designed to last.
Opting for large-volume concrete tanks is choosing a respectful, stable and truth-oriented production of the vineyard. At Sonoma by SAS, we design each model so that the winemaker can work with precision and freedom, accompanying the wine on a path where the terroir is expressed without artifice.
