A wine tank is a specialized vessel used in the winemaking process for fermentation, storage, clarification, and maturation of wine. These tanks are typically made of stainless steel to ensure hygiene, temperature stability, and durability, allowing winemakers to preserve the authentic flavor and aroma of their wine.
At COFF, we are proud to provide simple and economical solutions for the global wine industry. Headquartered in Ningbo, China, we have become the preferred supplier of stainless steel wine tanks in various sizes. Our tanks are designed with precision and innovation, offering winemakers around the world reliable equipment. Whether for small boutique wineries or large-scale operations, COFF’s stainless steel wine tanks deliver consistent performance and lasting value.
At COFF, we offer a wide variety of wine tank styles and structures to suit different winemaking needs. Each tank is carefully engineered to meet diverse production requirements — from small-batch fermentation to large-scale storage. In addition to our standard models, we also provide customized wine tank solutions, allowing you to design a system that perfectly fits your winery’s workflow, space, and production goals.
Our variable capacity wine tanks feature a flexible floating lid sealed with an inflatable gasket, allowing winemakers to adjust the internal volume to match any batch size. Constructed from high-grade SUS304 stainless steel, these tanks prevent oxidation and preserve wine freshness. Their versatility makes them ideal for small wineries, experimental batches, and seasonal production.
The floating lid wine tank built from 304/316 stainless steel. It includes a movable lid that sits directly on the surface of the wine, sealed with a food-grade inflatable ring to block air contact. This design is perfect for boutique wineries and hobby winemakers who manage smaller volumes and need secure, short-term storage with consistent quality control.
Our jacketed wine tanks are equipped with a dual-wall cooling jacket for precise temperature regulation during fermentation and maturation. The inner wall ensures hygiene and durability, while the outer jacket allows glycol or cooling water circulation. These tanks are perfect for wineries that require controlled fermentation environments, ensuring stable temperature, consistent flavor.
Square wine tanks are designed with a compact, space-saving rectangular structure that optimizes winery floor plans. Manufactured from certified stainless steel, they offer easy stacking, efficient cleaning, and strong durability. Their design is especially suitable for wineries with limited space or modular storage needs, maximizing capacity efficiency.
The conical wine fermenter features a cone-shaped bottom that enables natural sediment collection and simple yeast removal. Built with sanitary stainless steel and polished interiors, it ensures easy cleaning and complete drainage. This tank is ideal for wineries focused on precise fermentation control and clarity improvement, reducing manual labor.
At COFF, we provide a complete range of stainless steel wine equipment designed to support every phase of the winemaking process. From maceration and fermentation to clarification, stabilization, and maturation, our equipment ensures smooth, efficient, and hygienic production. We manufacture all our equipment from premium stainless steel materials (AISI 304 and 316), with brushed and polished welds that enhance durability and corrosion resistance.
The wine fermenter is the core vessel for transforming grape juice into wine through controlled fermentation. Built from food-grade stainless steel (AISI 304 or 316), it features a sealed top to maintain ideal fermentation conditions. The smooth inner surface and optional cooling jacket provide precise temperature regulation, ensuring stable yeast activity and consistent flavor development in every batch.
The wine mixing tank is designed to homogenize liquids, additives, or blended wines efficiently and hygienically. It is equipped with an integrated agitator, precision impeller, and reinforced lid for safe and stable operation. The stainless steel body and polished welds ensure easy cleaning and long service life. Ideal for equalizing flavor, color, and aroma, it provides winemakers with uniform, high-quality results.
The wine blending tank enables precise blending of different wines to achieve desired balance and complexity. It is designed with a flat or sloped bottom, integrated mixer, and sampling valve for quality checks during the process. Constructed from corrosion-resistant stainless steel, it maintains purity while preventing oxidation. Perfect for both small and large wineries, it creatives blending flexibility.
The wine brite tank is used for wine clarification and final conditioning. It features a domed top, sloped bottom, and sanitary fittings to ensure complete drainage and ease of cleaning. The tank can be equipped with a cooling jacket to stabilize temperature and maintain clarity. With its high-polish interior and airtight design, it ensures that your wine remains bright and ready for packaging.
The wine storage tank provides secure and long-term preservation for finished wine. Its vertical cylindrical design and sealed top structure prevent air exposure and contamination. Manufactured from durable stainless steel with brushed welds, it maintains the original flavor and aroma over extended periods. Designed for both temperature-controlled and ambient storage.
The wine distiller is designed for producing high-purity spirits or fortified wines through precise distillation. It includes a stainless steel boiler, condenser, and column structure that ensure efficient vapor separation and condensation. The system is fully sealed to maintain purity and prevent flavor loss. Suitable for professional distillers and wineries seeking diversification.

The life expectancy of a stainless steel wine tank depends on the material quality, usage, and maintenance, but generally:
High-quality stainless steel (AISI 304 or 316) tanks can last 20–30 years or more with proper care.
Regular cleaning and maintenance (avoiding scratches, corrosion, or chemical damage) significantly extend tank lifespan.
Environment and usage also matter: tanks stored in controlled winery conditions and used according to best practices will last much longer than those exposed to harsh conditions or heavy misuse.
In short, a well-maintained COFF stainless steel wine tank can provide decades of reliable service for wineries of all sizes.
Yes, it is perfectly safe to store wine in stainless steel tanks. Here’s why:
Hygienic and inert: Stainless steel (AISI 304 or 316) does not react with wine, preventing off-flavors or contamination.
Preserves flavor: It maintains the wine’s original aroma, taste, and color without adding any external influence.
Durable and airtight: Tanks provide secure storage, protecting wine from oxygen exposure and microbial contamination.
Temperature control: Many stainless steel tanks are jacketed, allowing precise temperature management during fermentation and storage.
Stainless steel is widely used in wineries worldwide, especially for white wines, rosés, and young reds, where preserving freshness and purity is a priority.
