Truncated wine fermentation tank
Achieve optimal temperature control and efficient maceration for red wine production with a tank design that enhances grape juice and marc interaction, ensuring superior flavor profiles in your final product.

Optimizes Fermentation and Temperature Control
The ST Truncated Tank from The SERAP Group offers an innovative solution for red wine producers seeking precision and efficiency in their fermentation process. This specialized tank enhances the maceration of grape juice and marc through its optimized truncated shape, promoting thorough immersion of two-thirds of the cap. The tank is constructed from AISI 304 stainless steel with a bright annealed interior finish, ensuring minimal cleaning and high corrosion resistance. With a capacity ranging from 25 to 206 hectolitres, it adeptly manages temperature variations for both cooling and heating phases, crucial during fermentation and maceration.
The ST Truncated Tank integrates into existing workflows with ease, featuring a laser-welded heat exchange system that delivers exact temperature control without internal tank marking. An isothermal option enhances efficiency by reducing energy usage through polyurethane foam insulation, preventing condensation. This equipment is ideal for crafting a range of red wines, including Cabernet Sauvignon and Pinot Noir, while maintaining controlled atmospheres for optimal storage conditions. The tank supports batch processing, offering wineries and large-scale producers a robust and flexible solution, backed by SERAP’s engineering expertise and support.
