Technology

From the best cru corks to the most innovative treatment technology … the patented “IGEA 2.0” process involves the individual stripping of the stoppers through the use of modular steam, controlled high temperatures and irradiation station.

100% Off Flavours free

Pyrazines free

Pyrazines are aromatic organic compounds responsible for a fragrant vegetable bouquet, among the most widespread notes we find the hint of green pepper and asparagus. 

Geosmin free

Geosmin is a molecule normally present in nature; the root of its name recalls the earth, in fact this molecule is responsible for the smell of earth, mold and fungus. 

Guaiacol free

Guaiacolo is an ether and its presence generates a hint related to the “pharmaceutical” smell. 

Suberin more available

Suberin is a hydrophobic substance located around the cork cells. Its presence guarantees IMPERMEABILITY to gas and liquids to a greater ELASTICITY to the stopper.

Greater elastic recovery

Greater durability

Thanks to the greater availability of suberin with IGEA 2.0 there is a greater elastic recovery.

Wine analysis

All tests were repeated on the same bottle 6 times and the reported value is the average. Many replicas have been performed with minimal variability. This leads us to state that IGEA caps keep the product homogeneously over time and work synergistically to maintain the quality of the wine.
