Stainless Steel Forkable Variable Capacity Wine Tanks

| Product Description 

Stainless steel variable capacity wine tanks are specialized vessels designed for the fermentation, storage, and aging of wine. They are particularly popular among small to medium-sized wineries and home winemakers due to their flexibility and ease of use.

Here are the key features and components of these tanks:

1)Stainless Steel Construction: Like many other types of wine tanks, variable capacity tanks are typically constructed from high-quality stainless steel. Stainless steel is favored in winemaking for its inert properties, resistance to corrosion, and ease of cleaning and sanitization.

2)Variable Capacity Design: The distinguishing feature of these tanks is their variable capacity design. Unlike traditional fixed-volume tanks, variable capacity tanks feature an adjustable floating lid or inflatable bladder that allows winemakers to vary the tank's volume according to the amount of wine being stored or fermented. This flexibility is particularly useful during fermentation when the volume of wine can change due to the release of carbon dioxide and other factors.

3)Sealing Mechanism: Variable capacity tanks are equipped with a sealing mechanism to ensure an airtight seal between the tank's lid or bladder and the tank body. This prevents the ingress of oxygen, which can negatively impact the quality of the wine.

4)Airlock and Valve: To allow the release of carbon dioxide produced during fermentation while preventing the entry of oxygen, variable capacity tanks are typically fitted with an airlock and valve system. This allows gas to escape without exposing the wine to oxygen.

5)Sampling Port: Many variable capacity tanks feature a sampling port, which allows winemakers to take samples of the wine for testing and analysis without the need to open the tank.

6)Optional Accessories: Depending on the specific requirements of the winemaking process, variable capacity tanks may be equipped with optional accessories such as temperature control jackets, racking arms for easy transfer of wine, and sight glasses for visual inspection of the contents.

Stainless steel variable capacity wine tanks offer winemakers a versatile and practical solution for fermenting, storing, and aging wine while maintaining control over volume and fermentation conditions.
