Wine Tanks
"We found using the 5,500 Litre Flextank wine tank enhanced the development of our Pinot Noir beautifully, prior to bottling"
Senior Wine Maker, Marlborough Winery.

Flextank Wine Tanks

Traditional stainless steel wine tanks are reductive. Flextank oxygen permeable wine tanks allow the ingress of small amounts of oxygen which enhances the development of the wine.

Advantages to Winemakers

Improved Wine Quality
Most wine will benefit from continued but limited oxygen exposure. Long term reductive conditions typical in stainless steel wine tanks encourage the formation of complex sulphur based compounds. This does not happen in Flextank wine tanks.

Low Oxygen Permeability
All Flextank wine tanks are rated for oxygen permeability unlike water tanks which have high permeability and resultant wine damage.

Ease of Use
Easily cleaned (tartrates don't stick like they do in stainless steel). 
Less chemicals are required for cleaning. 
Lighter than stainless steel, so easier to move.

Translucent
See your wine levels through the tank wall
Temperature Stable
The thickness of Flextank wine tank walls means they do not heat and cool like thin stainless steel

Long Lasting
Fully UV stablised for 30+ years with outside use

Robust
There have been no reports of damaged Flextank wine tanks post the Kaikoura and Christchurch earthquakes 

Complete Drainage
Unique Flextank design allows complete drainage of the wine tank 

Food Grade Polymers
FDA approved for wine storage
