Variable Capacity Tank
Variable Capacity Tank
This stainless steel storage tank is one of the oldest models in Letina’s lineup. Tried and tested throughout the years, it has proven its versatility and value time and time again.
Thanks to constant design improvements, the closed tank got better over the years – just like the wine it’s designed to contain.
Whether you want a simple storage tank, a fermentation tank, something to age your product in or even a mixing vessel – this closed top tank can do it all.
A large, dimpled jacket makes sure the temperature inside the sealed tank is always optimal. Thanks to the vertical construction of the cooling jacket, the stored liquids will be efficiently chilled even if the closed tank is not full to the brim.
Durable, high-quality materials enable the storage tank to stay in pristine condition, even after years of professional usage.

Frequently Asked Questions
What is a variable capacity wine tank?
A variable capacity wine tank is a stainless steel fermentation and storage tank with a floating lid that adjusts to the level of the wine. This design allows wineries to store different volumes of wine in the same tank while maintaining an airtight seal. Variable capacity tanks are widely used in modern wineries because they provide flexibility during fermentation, storage, and maturation.
How does a floating lid wine tank prevent oxidation?
A floating lid wine tank prevents oxidation by sealing the wine from oxygen exposure. The lid sits directly on the surface of the wine and features an inflatable gasket that presses against the tank wall, creating an airtight barrier. This prevents unwanted oxygen contamination while allowing the tank to be used at partial capacity.
What are variable capacity tanks used for in wineries?
Variable capacity stainless steel tanks are commonly used for multiple stages of winemaking, including:
Wine fermentation
Wine storage
Wine maturation and aging
Because the floating lid adjusts to the liquid level, wineries can use the same fermentation tank for different batch sizes, making them especially useful for small and medium-sized wineries with changing harvest yields.
How do you adjust the floating lid on a variable capacity tank?
The floating lid can be easily positioned using a mounted lifting arm. Once placed at the correct level, the inflatable seal is pressurized using a stainless steel hand pump, creating a tight airtight seal that protects the wine during fermentation or storage.
Why choose a Letina variable capacity wine tank?
