Bentonite
VULCOBENT Series
Vulcascot Bentonites are specially selected clays for adsorption and reduction of proteins, haze substances, and other colloids in must, wine, beverages, and liquid foods. They are used to reduce protein content early, improve clarification processes, and achieve stable, clear beverage quality.
Vulcascot offers various bentonites in powder and granular form, including low-iron and highly effective sodium and mixed bentonites for special filtration requirements.
VULCOBENT® K-UF
Potassium Bentonite (Ultrafiltration)
Ultrafine bentonite for clarification of fruit juices and beverages. Removes protein and colloidal turbidity with low abrasiveness.
Special applications:
Ultrafiltration systems, protection of membranes and pumps.
VULCOBENT® J-UF
For White or Rosé Wines
Highly effective bentonite for ultrafiltration processes in the beverage industry with high protein removal performance.
Special Applications:
Continuous UF processes, protein- and colloid-related turbidity.
VULCOBENT® Aktiv G
Granulated Calcium-Sodium Bentonite
Bentonite for protein stabilization of wine and beverages, effective even at high pH and gentle on color and sensory properties.
Special Applications:
Wine, must, and beverages with elevated protein content.
VULCOBENT® Protex P
Powdered Calcium-Sodium Bentonite
Highly active bentonite for targeted removal of protein and interfering substances from must, wine, and beverages.
Special Applications:
Intensive clarification and stabilization tasks with short contact times.
VULCOBENT® Top NA
High-Swelling Sodium Bentonite
Highly effective bentonite with low dosage requirement, particularly gentle on color.
Special applications:
Red wine, fruit juice and vinegar, applications with minimal product intervention.
PVPP
From VULCASCOT
Polyvinylpolypyrrolidone (PVPP) is a high-performance fining agent for selective removal of phenols and tannins. Our VULCOFIN X product line is available in powder and granular form and is ideal for stabilizing beer, wine, and juice.
VULCOFIN® X
PVPP for Beer Stabilization
VULCOFIN® X is a high-purity polyvinylpolypyrrolidone (PVPP) for selective adsorption of polyphenols in beer. It improves colloidal stability, prevents haze formation, and contributes to extended shelf life.

Silica / Xerogels
From VULCASCOT
Stable clarity through colloidal fine treatment – flavor-neutral, safe, and efficient.
The products in the VULCOSTABIL X/M series are based on high-purity silica gels (silica xerogels) specifically developed for colloidal stabilization of beverages. They selectively remove unstable proteins, phenols, and haze-forming agents, ensuring clear, stable final quality – without affecting taste or aroma.
The VULCOSTABIL products are characterized by their high adsorption capacity, fine particle structure, and good dispersibility. They can be used individually or in combination with PVPP (VULCOFIN X) and bentonite (VULCOBENT) – for maximum efficiency in stabilizing wine, juice, and beer.
