LEVEL2 GUARDIA™ is a new non-Saccharomyces wine yeast (Metschnikowia pulcherrima) selected from nature by IFV (Institut Français de la Vigne et du Vin), highly adapted for bioprotection in wines. It can help to managing microbial dynamics by encouraging beneficial microorganisms and repressing the growth of detrimental ones which is the fundamental principle of biocontrol. When applied early in the process, LEVEL2 GUARDIA™ we have early and efficient colonization of red musts.
LEVEL2 GUARDIA™ has been screened and chosen for its capacity to secrete naturally high concentrations of pulcherrimic acid, a strong iron chelating agent. This iron depletion makes the environment unsuitable for the growth of contaminant microbes. These unique characteristics make, LEVEL2 GUARDIA™ highly efficient against a wide range of undesirable microorganisms (oxidative yeast, Brettanomyces spp., acetic bacteria) that can result in faulty wines.
LEVEL2 GUARDIA™ is suitable for organic wine production according to EU regulation.
