Characteristics
Quercetin is a flavonol whose main function is to protect plants against abiotic stresses.
Quercetin precipitation in wines due to recurrent climatic stresses is becoming an increasingly global problem. In the next few years, this precipitation could affect a large number of varieties.
In order to limit this precipitation in the bottle, upstream intervention is therefore essential with this molecule complex.

SPECTRA® QF is a concentrated, micro-granulated enzyme preparation based on pectinase from Aspergillus Niger. These properties enable it to release bound quercetin, leading to its precipitation.
Application rate: 
​Recommended dose: 3 to 10 g/hL depending on bound quercetin content, contact time and temperature.
Packaging: 
100g
