- Activated carbon micro-pellets designed for powerful decolorization
- High surface area (>1000 m²/g) for efficient removal of polyphenols and catechins
- Removes browning and off-colors without stripping desirable varietal character
- Pelletized form avoids dust generation, improving safety and ease of use
- Suitable for both must and wine, with fast action and easy removal
Decoran Gran is an activated carbon in micro-pellet form, produced through controlled carbonization and activation. It excels at reducing excessive color, high-molecular polyphenols, and oxidized compounds in both must and wine. Unlike standard powdered carbon, its pelletized form significantly reduces dust, minimizes operator exposure, and enhances dosing accuracy. With an internal surface area exceeding 1000 m² per gram and pore sizes optimized for adsorption, Decoran Gran delivers fast, reliable color correction while preserving desirable sensory attributes.
Usage Protocol
- Dissolve Decoran Gran at a ratio of 1:10 (carbon to water, wine, or must) to create a slurry.
- Add the slurry to the tank with good circulation (e.g., pump-over).
- Once the target color reduction is achieved, remove solids via filtration or sedimentation. You may follow with gelatine or bentonite agents for final polishing.
Dosage Guidelines
| Application | Dosage (g/L) | Dosage (g/gal) |
| Mild decoloration | 0.005–0.02 | 0.02–0.08 |
| Moderate correction | 0.02–0.05 | 0.08–0.19 |
| Heavy decoloration | 0.05–0.1 | 0.19–0.38 |
