Optiesters
With an early application, during the first third of the alcoholic fermentation, OptiEsters® optimizes the ester potential of white, rosé, and thermovinified red wines.

Features and Benefits
Formulation: Inactivated yeasts naturally rich in amino acids and ergosterols.
Enological benefits:
- The specific formulation of OptiEsters® ensures the availability of the precursors of higher alcohol acetates and fatty acid ethyl esters. These compounds contribute to the production of fermentary esters, resulting in fruity and floral wines.
- Ergosterols reinforce the yeasts’ membrane, thus increasing their resistance to difficult conditions. This limits stress during fermentation and decreases the risk of organoleptic spoilages, giving cleaner wines.
Product Applications
Dissolve the product in 10 times its weight in water and directly incorporate while pumping over without aeration. It is recommended to add OptiEsters® when the density has decreased by 30 points.
AF Conditions:
- Temperature (T°C): 14 to 16°C
- Turbidity: 30 to 80 NTU
- Anaerobiosis
The use of our Excellence® STR or L.A Arom is recommended for a good aromatic display of the esters.
Dosage: 30 g/hL
