Features and Benefits
Formulation: Activated carbon in powder, vegetal origin.
Enological benefits:
- Géospriv is a carbon with high decontaminating and deodorising potential for musts and fermenting wines.
- Its adsorptive properties make it very effective at removing the tastes associated with geosmin without significantly affecting the colour.
- Géospriv can be used to treat musts and fermenting red, white, and rosé wines with earthy characters (geosmin).
Product Applications
Geospriv is used on must or new wine still in fermentation. Geosmin is contained in the grape skin and is gradually extracted during maceration. If the treatment is carried out too early, only the proportion extracted at the time the product is introduced is eliminated.
Hydrate Geospriv in water or in the must to make up a paste, wait 2 or 3 hours, and incorporate it during pumping-over.
Application:
- Classic maceration: Introduce 48 hours after the start of fermentation. Split 50% 48 hours after starting and 50% after running off to adjust the treatment.
- Thermo-treatment: Liquid phase (pressing) or solid phase (maceration): introduce 48 hours after the start of fermentation.
- Beaujolaise maceration: Add after racking.
- Press wine: Treat immediately after pressing.
Dosage: 10 to 60 g/hL according to the recommendations of your oenologist or following a laboratory test.
Maximum legal dose (EU regulation): 100 g/hL.
