JUCLAS Micro-Oxygenation Meets Enologica Vason Tannins
Oxygen, when applied with precision, is one of the most powerful tools in winemaking.

• In small, controlled doses, it supports yeast metabolism and prevents reductive problems.
• It promotes the polymerization of tannins and anthocyanins, fixing color and improving the structure of red wines.

The JUCLAS MICRODUE® PLUS system ensures that oxygen is delivered with absolute accuracy. When combined with the right tannins from the Enologica Vason range, the result is a complete solution for wines with intense, stable color and elegant balance.

MICRODUE® PLUS
The safe use of oxygen to add value to wine

• Precision micro-oxygenation
• Volumetric piston dosing: accuracy and repeatability
• Up to 6 dosing points (expandable to 30 with Multipoint)
• Oxygen dosage: 20 mL/h to 54 L/h per point
• Portable and intuitive

MICRODUE® PLUS guarantees precise, safe, and flexible oxygen management, creating the ideal conditions for color stabilization.

The Combo Effect: Oxygen + Tannins

While MICRODUE® PLUS ensures accurate oxygen delivery, its effect is maximized when combined with selected tannins designed to protect and stabilize color.

SMARTAN® UVA SG

• Grape catechinic tannins with high efficacy in stabilizing color fractions
• Useful from the earliest vinification phases, during fining, and in micro-oxygenation
• Prevents oxidative processes in musts and young wines (including Botrytis-affected grapes)
• Supports tannic structure and facilitates anthocyanin stabilization during red vinification

PREMIUM® UVA SG

• Derived from procyanidin and catechinic origins, highly reactive to proteins and oxidases
• Extends shelf life and enhances resistance to oxidation
• In red vinification, fixes anthocyanin fractions during maceration and racking
• Reduces the need for SOâ‚‚ thanks to its antioxidant action

PREMIUM® LIMOUSIN SG

• Extracted from oak with a delicate and balanced profile
• Provides redox stability, improves body, and enhances aromatic complexity
• Helps stabilize the color fraction of red wines, especially when natural cask release is insufficient
• Effective in both early fining and final assembly phases
