Oak maturation trial results show cost savings
This article is based on a presentation at the 2013 Winery Engineers Conference in McLaren Vale, South Australia, in June 2013.
FOR THE PAST 25 years, Ausvat has been developing an alternative wine storage and oak maturation system to that of conventional oak barrels. The original ‘Stakvat’ vessel concept was of a 225L volume design and the first commercial prototype was supported and launched by the late Dr Bryce Rankine at a McLaren Vale winemakers’ forum held at Middlebrook winery on 23 August 1988.
Current research and development The last four years has seen rapid advances in the development of engineering products for controlled wine maturation.
These advances have been assisted by the previous R&D involving the Australian wine industry and teaching Institutions, and by utilising today’s engineering materials combined with advancements in maturation vessel design. The vessel is still known as “Stakvat” today, but is now in a very different form to its predecessors.
