Strong fermenter for freshness and fruit expression

O-MEGA™ is the most robust strain in Scott Laboratories’ portfolio. It is highly suitable for conducting malolactic fermentation in high alcohol, low temperature, or low pH situations. O-MEGA lends balance and complements aromas by bringing freshness; however, it is not recommended for wines with herbaceous or vegetative notes, as these will be amplified.
  • Contributes to freshness and mineral/citrus notes in white wines
  • In red wines, notes of red and dark berries like red currant, strawberry, blackcurrant, and blackberry are increased
  • Selected for its ability to complete MLF even under challenging wine conditions of high alcohol, low pH, and low temperatures
  • May help stabilize color due to its slow degradation of acetaldehyde
  • Has a late degradation of citric acid resulting in very low diacetyl and VA levels, and is tolerant to levels of lactic acid that can be inhibitory to other ML strains
  • Oenococcus oeni isolated in the south of France by the Institut du Français de la Vigne et du Vin (IFV) in Burgundy
