What Is The Avantage of Pump-Over Wine Fermenter Tank?

Currently we received some inquiry about pump-over wine fermenter tank, and what is the pump-over wine fermenter? And What are the benefits of using it for wine growth?

1.What is the pump-over wine fermenter tank?

A pump-over wine fermenter tank is a piece of winemaking equipment used during the fermentation process, particularly in red wine production. The tank is designed to facilitate a specific technique called “pump-over”, which is essential for extracting color, flavor, tannins, and other compounds from the grape skins.

How It Works:

Fermentation: During fermentation, grape skins, seeds, and other solids (known as the “cap”) rise to the top of the tank, forming a thick layer.

Pump-Over Process: To ensure even extraction, a pump-over wine fermenter tank uses a pump to draw the fermenting juice from the bottom of the tank and spray it over the cap. This process helps to submerge the cap and keep it wet, promoting better extraction of desirable compounds from the grape skins.

3.What are the benefits of using pump-over wine fermenter for wine growth?

Enhanced Extraction:By keeping the grape skins in contact with the fermenting wine, the process enhances the extraction of desirable compounds, leading to wines with richer color and more complex flavors.

Temperature Control:The pump-over process can also help regulate temperature by redistributing heat generated during fermentation.

Oxygenation: Pumping over also introduces a controlled amount of oxygen, which can benefit the fermentation process.

A pump-over wine fermenter tank is a critical machine in producing high-quality red wines, allowing winemakers to control and optimize the extraction and fermentation process.
