The Mighty
Conical
Five Sizes Up To 1,470 Gallons
The conical shape promotes natural lees circulation, protecting the wine from oxidation throughout fermentation. Its geometry is especially suited for red wine production, as it enhances cap soaking and breakup—intensifying maceration and flavor extraction. This design also makes it the optimal choice for délestage.
Our popular Concrete Conical tanks come in five sizes and styles, with the flexibility to be custom-modified to suit your winery’s unique needs. Choose between open-top or closed models, both equipped with our innovative “Pivotal” manways for easy access. For installation, tanks can be placed on a raised foundation, our adjustable steel ring support, or matching concrete legs.

Enhanced Cap Management
Easier Punch-Downs & Visual Monitoring: Open tops allow winemakers to manually or mechanically punch down the cap (the mass of skins, seeds, and stems that float to the top), ensuring better extraction of color, tannins, and flavor.
Increased Oxygen Exposure
Controlled exposure to oxygen during fermentation promotes healthy yeast activity and can soften tannins, contributing to a rounder, more approachable wine.
Small Lot Production
Ideal for artisanal or boutique winemaking, open-top fermenters are often used for small batches, experimental lots, or premium cuvées where hands-on control is essential.
Volatile Compound Release
The open environment allows undesirable volatile compounds (like sulfur dioxide or hydrogen sulfide) to dissipate more easily, resulting in purer aromas.
