Enhance varietal characters in Sauvignon Blanc
Publiée le 26/07/2019 14:33
Sensory analysis
Sauvignon blanc has been one of the largest wine success stories globally since the late 20th century. This French white grape variety has been cultivated in the Loire Valley and Bordeaux regions for centuries. Yet, it became very popular on an international level once New Zealand started to grow it and produce very fruity Sauvignon blanc wines in the 1980s. It has become New Zealand's most cultivated variety and holds its success mainly to the varietal aromas of thiol compounds.
How to avoid the production of sulfur off flavors in red grape varieties with high reduction potential

Viticulture Sensory analysis Stabilisation & Bottling
Some red grape varieties, such as Shiraz, Pinot noir, Merlot or Tempranillo, have a certain trend to express sulfur off flavors and reduction characteristics. These characteristics mask the red fruit aromas and thus have a negative impact on wine.
To tackle this issue and bring a new solution to winemakers, Lallemand Oenology, Montpellier SupAgro and INRA Montpellier have collaborated and designed an innovative selection technique for yeast.

Innovation Vinification process
In winemaking, wine enzymes are used as accelerators as they speed up the natural reactions in wines that would otherwise occur more slowly. For most enzymes, the addition to grapes in the press as early as possible helps to extract aroma precursors, reduce the duration of maceration and increase juice yield.
For this new season, we are proud to announce the launching of our new high performance liquid pectolytic enzyme for pressing: LALLZYME HP™

Innovation Sustainable development Stabilisation & Bottling
Protection of rosé and white musts against oxidation at the earliest stage of the winemaking process is key to prevent browing and loss of aromas in wine. The addition of inactivated dry yeasts (IDY) containing glutathione is now well known from the winemakers as a tool to limit oxidation phenomena in musts and wines. GLUTASTAR™ is a new specific inactivated yeast with guaranteed glutathione level offering more benefits to the wine than protection against oxidation only.
