Premium “Dexter” Style Maturation, Fermentation and Storage Tanks

Dexter series tanks are named for winemaker Joe Dexter, proprietor of Lobo Loco Wines in Wilton CA. Joe produced the first gold medal winning wine in the USA using Flextank oxygen permeable maturation vessels.
Dexter tanks feature a patented 19 inch diameter man way opening, hermetically sealed with the clamp style lid and gasket shown. The clamp lid requires neither tools nor herculean strength to install or remove as opposed to similar diameter threaded openings. As the tank is filled, wine impacts the convex lower surface of the lid and then fills the gap between lid and tank. Final fill is through the 2 inch threaded bung hole after the lid has been clamped in place. Minimal entrapped air results.
The wide opening makes for a versatile tank that can be used for primary and secondary ferments in addition to maturation storage. Excellent access for cleaning or the addition and removal of oak adjunct products.
Two thicknesses of vessel provide passive micro oxygenation performance similar to either second year barrels (Maturation Weight) or “neutral” barrels (Heavyweight) at cellar temperature (55F). The thicker units are primarily intended for aromatic whites where only minimal micro oxygenation is desired.

Flextank “ECO” style Maturation and Storage Tanks.
Both ECOnomical and ECOlogical, the Flextank ECO series tanks are the lowest cost approach to replacing oak barrels for wine maturation with oxygen permeable polyethylene. ECOlogical as they are fully recyclable after a long service life and make efficient use of oak alternatives such as Staves, Spirals, Beans or Chips.
ECO tanks feature a molded in male thread and rugged 6 inch diameter screw cap with a 2 inch threaded center bung. This provides sufficient access for cleaning the inner top surface and the addition or removal of oak adjuncts. This cap traps minimal air and accepts accessories.
ECO tanks are available in 30, 70, 200 and 300 gallon sizes in “Maturation” Weight designed to simulate the oxygenation performance of the average second year barrel at cellar temperature. The 70, 200 and 300 gallon units are also available as “Heavy-weight” versions that have thicker tank walls, and simulate older “neutral” barrels.

FERMENTATION TANKS
Apollo-Winemaking Innovation from Flextank USA
A latest trend in winemaking is the Egg shaped tank. Winemakers report superior fermentation results in these tanks due to the shape promoting both internal convection mixing and cap concentration. Flextank introduces the first polyethylene “egg”. We call it “Apollo” because it looks like the famous Apollo Space Capsule...
Why Should You Take a Look At Apollo?
- Versatility and costs: Apollo and polyethylene the medium of choice for both small lot production of ultra premium wines and experimentation with fermentation parameters
- Maneuverability: forklift or other lifting apparatus using two bolt on pivots. A full tank is easily rocked back and forth to re-suspend lees, for example
- Easy To Handle: Apollo is easily manipulated by hand and can be quite stable at intermediate positions. The lifting apparatus can range from the sophisticated to a simple sling suspended from a forklift.
Once fermentation is complete Apollo serves as a long term storage (similar oxygen permeability to a neutral barrel) or general purpose tank for the winery. Replace those bin fermentors with Apollo and enjoy better fermentation conditions and year round use.
Large Fermentors.
Super tough, food contact, high-density polyethylene. This material does not interact in any way with the juice or wine, is taint free and is very easy to clean, as tartar and other deposits from the wine don't stick to the surface and the material is not stained by red wine pigments.
Flextank’s 900 gallon open fermenter is rotationally-molded in super tough, food contact, high-density polyethylene. This material does not interact in any way with the juice or wine, is taint free and is very easy to clean, as tartar and other deposits from the wine do not stick to the surface and the material is not stained by red wine pigments.
