Natural protection against oxidation and spoilage microorganisms
LEVEL2 INITIA™ is a non-Saccharomyces yeast (Metschnikowia pulcherrima) selected from nature in Burgundy with the IFV (Institut Français de la Vigne et du Vin). LEVEL2 INITIA™ is an innovative and complete bioprotection tool developed to face the challenges of reducing SO2 use in white and rosé prefermentative steps. LEVEL2 INITIA™ is the first bioprotection yeast developed to limit oxidation phenomena in the early steps of winemaking due to its dual action of consuming oxygen and decreasing copper levels. Indeed, LEVEL2 INITIA™ has been selected from more than 100 strains of Metschnikowia pulcherrima for its high dissolved oxygen consumption capacity. When used during pre-fermentative steps, it can partially decrease copper content, known as a catalyzer of oxidation reactions. LEVEL2 INITIA™ has the capacity to control a wide range of undesirable microorganisms. As it is non fermentative and able to grow at low temperatures, LEVEL2 INITIA™ is a great biological tool particularly well adapted to manage prefermentative steps in white and rosé vinification. LEVEL2 INITIA™ is suitable for organic wine production in the EU.Necessidades de nitrogénio
