Two new Lallemand products are now listed and comply with the OMRI Standards Manual and the OMRI Policy Manual, which are based on the requirements of the USDA National Organic Program Rule (7 CFR Part 205). The OMRI listed products are Reduless® and Opti-LEES®. Reduless® is a unique yeast derived product with immobilized copper developed to reduce sulphur compound off-flavours and improve wine quality. It will reduce levels of hydrogen sulphide, diethyl sulphide, dimethyl sulphide, mercaptans and other sulphur related off-flavours in wine. Those compounds can lead to strong negative assessment by consumers and depreciation of the wine. Reduless® can be used on red, white and rosé wines and will enhance overall quality and fruit character of the wine by reducing its green herbaceous character. Opti-LEES® is a specific inactivated yeast developed and produced from a specific yeast selected for its ability to autolyse easily and release high quantities of polysaccharides. Applied towards the end of alcoholic fermentation, Opti-LEES® is a useful tool for the management of aging on lees, enabling a better control of lees quality and a faster “aging” effect due to the release of polysaccharides. In addition, the sensory analysis shows the positive impact of Opti-LEES® on the voluptuous perception of wine. These new OMRI listings are an important and continuing step for Lallemand as it provides organic winemakers with quality products. Reduless® and OptiLEES® join other OMRI listed products such as Opti-White®, Opti-Red® and Go-Ferm® Protect, Fermaid O™, GoFerm®, Noblesse™ and Fortiferm®.. The Organic Materials Review Institute is a national non-profit organization in the United States that determines which input products are listed for use in organic production and processing. OMRI listed products may be used in operations certified “organic” under the USDA National Organic Program (www.omri.org).
