Innovation fueled by 9 decades of experience
Experience. Technology. Founded on the Italian island of Sardinia in 1941, Ganau relies on nine decades of experience and the integration of modern technology in its pursuit to produce the finest corks possible. By focusing on sustainable practices, stringent quality control standards, and innovative production techniques, Ganau has revolutionized the way cork is processed in order to meet the demands of eminent winemakers everywhere.
Ganau has sustained its long-standing reputation for unparalleled quality by developing industry-leading cleaning and quality control procedures aimed to eradicate taint from cork closures.
Bottled Perfection
UNIQ, TCA FREE GUARANTEED
≤0.3 ng/L 2,4,6-Trichloroanisole (TCA)
We didn’t just engineer performance.
We mastered consistency.
Precision engineered.
Consistency delivered.
Precision starts with material selection
The granules are produced from carefully selected raw materials, including by-products from natural cork and disc production. Before processing, each granule is sorted by size and density to remove impurities and ensure exceptional consistency.
Eliminating TCA, preserving nature
QUANTUM is a chemical-free thermal desorption technology designed to remove TCA and other sensory deviations from cork granules using temperatures of up to 180°C and a steam counterflow system — all while preserving the cork’s natural properties.
Twin compression
Each cork is individually agglomerated through a compression process rather than extrusion, using food-safe binders to ensure integrity, consistency, and long-term performance.
Precision oxygen management
Engineered across five OTR levels, UNIQ gives winemakers precise control over oxygen transfer throughout the wine aging process, delivering greater flexibility and consistency.
Natural cork. Refined.
With 98% cork by volume, UNIQ preserves the authentic character of natural cork while delivering outstanding consistency and long-term performance.
Organoleptic excellence over time
Consistently validated across multiple tastings, UNIQ delivers lasting purity, balance, and sensory reliability throughout aging — making it ideal both for long-aging wines and for white wines that demand exceptional freshness.
Validated by several independent laboratories, UNIQ has scored the best in sensory on multiple trials and is the choice for winemakers looking for a TCA-free closure (≤0.3 ng/L 2,4,6-TCA), consistency and dependability. Constructed from natural cork micro-granules selected for uniform sizing of 1.5mm or smaller, UNIQ is the ideal closure for long aging wines as well as white wines needing complete neutrality. UNIQ is offered in five different OTR levels providing winemakers with the ultimate flexibility in wine aging.
