GEOSORB® GR is an enological carbon from vegetal origin.
It is characterized by a specific porosity that allows the selective adsorption of geosmin and octenone.
• Action on geosmin: 15 to 25 g/hL (150 to 250 ppm).
• Action on octenone: 35 to 45 g/hL (350 to 450 ppm). EU regulations limit the use of activated carbon to 100 g/hL (1000 ppm).
Please refer to your oenologist. Regulatory aspects: The use of active carbon in oenology is no longer subject to authorisation but is still under regulations. Check your local legislation in force
USA Regulation: No limitation to clarify and purify wine.
