The revolutionary Flextank system of winemaking was meticulously engineered to give a precision level of linear micro-oxygenation in multiple tank options. This enables winemakers to control various levels of oxygen transfer rate (OTR) which is essential in winemaking.

The semipermeable polymer tank walls have a specific gradient for allowing oxygen molecules to move through the vessel and into the beverage providing micro-oxygenation. However, the molecules you want to retain, such as ethanol and water, are blocked and do not escape a Flextank wall like they do in a traditional barrel. This makes constant cellar humidity monitoring and angel’s share a thing of the past!
