Winemaking is a venerable art, steeped in millennia of tradition, with each bottle a testament to vast expertise and heritage. Recognizing that every winery is distinct, operating within its unique set of conditions, we provide tailor-made wine fermentation tanks, aging, and wine storage tanks, precisely aligned with the specific objectives and requirements of our clients.
Utilizing stainless steel of either AISI 304 (DIN EN 1.4301) or AISI 316 (DIN EN 1.4401) standards, we ensure superior quality through passivated surface welding techniques. Our offerings range from bottom-sitting to leg-standing and split configurations, with options for double-wall insulation or integrated cooling and heating systems to facilitate the creation of exquisite wines. Upon confirming a bespoke specification that suits your winery’s unique demands, we commit to the shortest turnaround time, delivering a fully installed, rigorously tested, turnkey system to our clients.
Our smallest vessel begins with wine tanks at 10 hectoliters, scaling up to 1500 hectoliters manufactured at our premises. For capacities exceeding this, we offer the production of specially designed wine fermentation tanks, customizable with an array of additional features, directly at your site.
Our wine storage tanks are designed for the preservation of finished wine, with stainless steel as the material of choice due to its exceptional properties in preventing oxidation and maintaining chemical neutrality. This ensures the wine’s natural flavors and freshness are preserved for extended durations.
Featuring a suite of customizable options, our stainless steel wine tanks can be equipped with drainage and sampling valves, temperature probe ports, cleaning and filling systems, dome tops, access manholes, and breather valves. Every aspect, from feature placement to tank dimensions, surface treatment, and the choice between legged or flat-bottomed bases, is tailored to seamlessly integrate with your existing setup.
We offer an array of additional accessories like rotating spray heads, pivotable sampling valves with cleaning heads, and washing spheres, supporting the post-use cleaning process.
Since the 1950s, stainless steel has been the material of choice in the winemaking industry, prized for its unmatched compatibility with the vinification process. The key to its widespread adoption lies not only in the customizable dimensions and configurations but also in the non-porous surface, facilitating effortless sanitation. Our wine fermentation tanks ensure a sterile environment even at the welds, ready to receive the freshly pressed must in a condition free from bacteria and germs.
This allows the wine to maintain its vibrant freshness and the integrity of its flavors, a critical factor for the nuanced and delicate profiles characteristic of today’s sought-after white wines. For vintners dedicated to white wine production, we advocate tanks designed with a conical base for simplified sediment removal. We also specialize in the creation of double-walled insulated or refrigerated wine tanks, providing the exacting temperature control necessary for preserving the unique varietal qualities of each wine.
Mastering the art of fine red wine maturation demands deep expertise, precise attention, and intensive effort, particularly when managing the grape pomace cap during and post-fermentation. Our stainless steel wine fermentation tanks, designed for red wine production, streamline these complex processes. This innovation allows wineries to initiate the aging process in these tanks before possibly transferring the wine to oak barrels for further maturation, achieving the nuanced flavors sought by connoisseurs.
For creating exquisite red wines, we advocate for our flat-bottomed stainless steel wine tanks, featuring a rectangular hatch for the efficient disposal of grape pomace. To optimally manage the pomace cap’s moisture, we recommend our work roller, a must circulation pump, or a rotating device tailored for horizontal tanks, enhancing the fermentation process. We provide both sealed and floating-lid tank options.
Our stainless steel wine tanks are designed for ease of maintenance, enhanced by BA (IIId) coatings and polishing, along with a variety of fittings. This ensures a pristine, hygienic environment for creating and storing your products.
Beyond mere dimensions, we custom-fit the tank’s configuration and accessories to your specifications. From the base and apertures to probes, fittings, and specialized attachments, your wine tank is manufactured to be distinctly yours.
The standout attribute of our stainless steel wine tanks is their remarkable longevity. By augmenting the material’s inherent strengths with superior craftsmanship, we guarantee your tank will deliver consistent performance for generations.
Temperature control is crucial in winemaking. Our innovative double-walled, insulated wine tanks, complete with cooling jackets, offer constant temperature during fermentation, adaptable through automated systems. We custom-design the cooling jacket for your specific vinification process, cooling the entire surface for white wines and the lower part for red wines. We also offer temperature control for outdoor wine tanks with cladding.
Leveraging technology can significantly enhance the automation of winemaking processes. From the initial stages of grape reception, destemming, and crushing, to the precision of universal cross-flow filtration and liquid cooling systems, we provide comprehensive design, manufacture, acquisition, and installation services. Enhance the fermentation process with our specialized wine equipment such as work cylinders or rotating devices for optimal cap moisture management, or pump systems designed for effective recirculation over the grape cap. These solutions can be part of a comprehensive, fully automated wine system, optimizing every step of the winemaking process.
While the winemaker’s expertise, experience, and personal touch are irreplaceable, automation, remote control, and monitoring represent vital advancements in the field of winemaking. Our tanks can be equipped with automated control systems, allowing for the continuous remote monitoring of the fermentation tanks’ conditions—such as fill level and temperature—via computer or smartphone. With the right equipment, certain operations, like racking or mixing, can also be remotely controlled, bringing a new level of precision and convenience to the art of winemaking.
Choosing the right material is a key step in stainless steel tank manufacturing. Machinability and the type and duration of environmental exposure are two major factors that influence this decision.
At Duna Steel Tech, we’re committed to improving both the efficiency and quality of our work. To support this, we continuously invest in the right tools.
In recent years, stainless steel wine tanks have become increasingly popular due to their many advantages in fermentation and storage. Their durability and value retention make them a reliable long-term solution. As a result, selecting and using the right wine tank has become an essential part of everyday winemaking.
