What exactly is a Variable Capacity Tank?
It is a tank with a floating lid, typically made of stainless steel, where the lid rests directly on the surface of the wine, olive oil or other liquid. It uses an inflatable seal or gasket to create an airtight seal, eliminating headspace to prevent oxidation and spoilage.
Key Features and Benefits:
Variable Capacity: Allows winemakers and olive oil producers to store different volumes of wine or oil in the same tank, making it perfect for small batches.
Oxidation Prevention: The lid seals at the exact liquid level, minimizing contact with air.
Versatility: Used for storage, settling out of solids, aging, and as primary fermentation for wine.
Components: Typically includes an air pump for the inflatable seal, a pressure gauge. Larger tanks include ropes or lift system for raising and lowering of the lid.
These tanks are widely favored at small-to-medium sized wineries and olive oil producers for their flexibility and effectiveness in protecting wine and oil quality.
