Contribuição Sensorial Geral

Active bioprotection for red wines

Managing microbial community dynamics by encouraging beneficial microorganisms and repressing the growth of the detrimental ones is the fundamental principle of biocontrol. Level2 GUARDIA™ is a new non-Saccharomyces (Metschnikowia plucherrima) selected from nature by IFV (Institut Français de la Vigne et du Vin), highly adapted to this purpose of bioprotection in wines. When applied early in the process, the excellent implantation and growth performance of LEVEL2 GUARDIA™ allows an early and efficient colonization of various ecological niches. LEVEL2 GUARDIA™ has also been screened and chosen for its capacity to secrete high concentrations of pulcherimmic acid, a strong iron chelating agent. This iron depletion makes the environment not suitable for the growth of other contaminant microbes. Because of these unique characteristics, LEVEL2 GUARDIA™ is highly efficient against a wide range of undesirable microorganisms (oxidative yeasts, Brettanomyces spp., acetic bacteria)
