Tank Innerstave in any wine tank allows wineries to obtain premium oak barrel character in larger wine vessels at a cost savings over traditional premium oak cooperage sources. It is designed for use in all phases of winemaking in 5,000 to 100,000 gallon tanks.

Tank Innerstave is custom-made with a radial design stainless steel support structure for every size wine tank. The design allows all oak and stainless steel surfaces to be exposed to washing devices, enhancing cleanability. Stainless steel, jacketed tanks allow for finite temperature control and increased use of micro-oxygenation to allow the tanks to perform more like wine barrels. The system is designed to impart oak flavor at the same rate as new premium oak barrels.
