Premature decay of wine
This is linked to the wine’s structure, its composition and to the quantity of oxygen that is dissolved during its evolution until bottling
Prevention:
It can be dealt with by introducing preventative factors:
- Reductive vinification (there is a specific procedure)
- Must oxidation
- Light sulphiting agents during refinement and at bottling (V Antiox)
- The use of tannins that are able to regulate oxidation reactions
- Addition of LPA® to contribute to correct redox management
- Oxygen monitoring during wine production stages
- Removal of oxidisable polyphenols through targeted clarifications (Clarito® SP, PVPP)
- Removal of oxidisable polyphenols through active filtration during precoating (Clarito® Filter R, Clarito® Filter W, Clarito® Filter Super)
- Micro-oxygenation (Microdue® Plus)
Correction:
It can be dealt with by introducing corrective factors;
- Cleaning with inert gases through Ju.Cla.S Gas Mixers
- Selective removal of oxygen through the Active-Perstraction technique (REG EU no.1251/2013)
- Removal of oxidisable and oxidised polyphenols through clarification (Clarito® SP, PVPP)
- Removal of oxidisable and oxidised polyphenols through active filtration during precoating (Clarito® Filter R, Clarito® Filter W, Clarito® Filter Super).
