| Product Description 

The tonne open-top  fermenter is a vital component in wine production, serving as a critical catalyst that enables fermentation to unfold seamlessly.

This vessel stands out due to its unique design, which features an open top that permits ambient and yeast to move in and out freely while fermentation is taking place. This openness creates a natural setting for fermentation, allowing yeast to engage more efficiently with the fermenting material, leading to unique tastes and scents.

The product's longevity is guaranteed by the addition of sturdy angle steel reinforcements to its open top design.
