Secure and highly efficient

O-Mega 1-Step™ was isolated and selected in South of France by the Institut Français de la Vigne et du Vin (IFV) for its capacity to quickly achieve malolactic fermentation (MLF) in a wide range of applications.It is a secure and efficient strain which tolerates low pH or high alcohol conditions. Reliable on white, red and rosé wines, complements fresh and fruit driven wines and helps to stabilize red wine color because of its slower degradation of acetaldehyde.
