STAKVAT™ EXCELS FOR WINE MATURATION
The Stakvat™ wine storage system of Ausvat Pty Ltd, with its associated oak technologies, provides an ideal means for winemakers to control oxygenation and maturation of wine, at a time when over supply in the industry means that rapid oxygenation is likely to be avoided in favour of more prolonged and controlled development.
In
Innovation in Oaking Wine
Stakvat® is an oaking system and a feasible
barrel equivalent
for
the production, storage and maturation of barrel aged wines.
Stakvat® has a wine volume capacity of 900 litres equal to 4
barriques or 3 hogsheads with the option of insist temperature
control through inbuilt cooling tubes.
Twenty years of research and
development including 15 years of
field trials has seen the concept successfully evolve into an
economical and versatile storage and maturation vessel for barrel
aged wines.
Cost Comparisons
In the first
year of purchase, the overall cost of the
Stakvat®
concept is comparable to the cost of new barrels. When it comes time for
oak replacement, new oak can be replaced for around a
quarter of the
cost of new barrels with the
owner retaining the stainless steel vessel.
Used Stakvat® walls can be reclaimed and used as internal battens.
Barrel reclaimed oak can be chosen as an option as internal oak battens in Stakvat® reducing oaking costs even further.
Stakvat’s® unique design enables vats to be fork lifted from any of the four sides stacked in multiples up to five high allowing 60% more wine to be stored in the same space that would be occupied by barrels.

Controllable Oak Flavour Adjustments
Stakvat®
has two replaceable and reclaimable quality oak walls.
One of the walls is an out-swinging door as shown above and
allows for easy access for cleaning and oak replacement
Internal oak battens are threaded on to a pair of reuseable stainless steel rings as shown below.
Oak flavour
intensities can be easily
adjusted to less than or equal to barrel regimes or to
fast extraction
by deliberately overoaking for blending wine with larger
storage tanks.
This can be done by adjusting the number of internal battens by simply
threading single battens on or off the circular oak rack through the
side door opening of the
Stakvat®.
Other Features
Use of
chemicals
for cleaning is greatly
reduced
as Stakvat®
has an out-swinging door that allows easy oak replacement and cleaning
using high pressure rainwater as all surfaces are easily visible through
the door opening.
