Get more out of every row
Square profiles align closely with walls and neighboring tanks, reducing unusable gaps. The result: up to 20% more capacity within the same footprint — or the same capacity in a smaller, more orderly cellar.
Product Code: G
Give the cellar its order back.Let the rows be worth looking at.
A closed, jacketed square fermenter for red and white fermentation, storage and aging — planned around how the rows meet the room, and what the room looks like once they do.
Why this tank
A Diamond Square Fermenter is not chosen for its facets. It is chosen when the tank rows have started deciding the cellar — walkways, platforms, cleaning routes and productive capacity all set by where the tanks stand — and the curved gaps between round tanks have stopped paying their way.
For the wine, nothing is given up to get the geometry: closed fermentation, jacketed control, and an interior curved and radiused so a square tank stays as washable as a round one. For the cellar, it means square profiles align with walls and neighbouring tanks, and floor area turns back into capacity.
The decision is also seen. A cellar people walk through is judged on its rows, and a faceted top that catches the light turns necessary equipment into something worth putting on the route rather than routing visitors around.
01
Square profiles align closely with walls and neighboring tanks, reducing unusable gaps. The result: up to 20% more capacity within the same footprint — or the same capacity in a smaller, more orderly cellar.
02
Ferment in it during vintage. Store in it through the year. One tank format supports both phases, simplifying equipment planning across the cellar.
03
Aligned square rows bring visual clarity to the cellar, while diamond-faceted surfaces give it a character visitors remember.
