Lallemand introduced this natural yeast derivative nutrient for use in white wine production after an extensive three-year research program.
When added to the juice at the onset of fermentation, Opti-WHITE imparts anti-oxidative properties that work synergistically with SO2 allowing the winemaker to potentially lower the SO2 dosage.
Opti-WHITE may also be added in the last stages of alcoholic fermentation to help bring out flavor profiles often associated with aging on lees.
Dosage: 30-50g/HL at beginning of fermentation
Opti-WHITE® is now certified organic by OMRI!
When added to the juice at the onset of fermentation, Opti-WHITE is made using a specific production process that results in a yeast derivative rich in polysaccharides and high in anti-oxidants. These anti-oxidative properties work synergistically with SO2 allowing the winemaker to potentially lower the SO2 dosage.
