SafŒno™ FV 19 sensory features

For fruity and smooth red wines:
SafOEno™ FV 19 has the ability to mask the vegetal notes of certain wines while improving the sensations of fruitiness and smoothness. By bringing sweetness and roundness to wines, SafOEno™ FV 19 greatly improves the quality perception of the tannins while decreasing their astringency.

SafOEno™ FV 19 also produces a significant amount of fruity fermentative aromas ranging from red fruit (pomegranate, cherry) to black fruit (blackcurrant) and is the ideal choice for the production of fruity and velvety red wines crafted for a quick release to the market.

SafOEno™ FV 19 is a great tool for the vinification of elegant and smooth wines from varieties such as Merlot, Cabernet Sauvignon, Syrah, Grenache, Tempranillo, Nero d’Avola and Nebbiolo.

The Lesaffre know-how and continuous yeast production process improvement generates an exceptional quality of dry yeasts able to resist a very wide range of uses, including by-passing acclimatization, cold or no rehydration conditions, without affecting their viability, kinetic and/or analytical profile. Winemakers can choose to use our E2UTM yeast with the process that fits best their needs:

  • Direct inoculation: Inoculate the desired quantity of yeast directly into the must in the fermentation tank, taking care to homogenize the entire volume. In white or rosé wines, ideally, sprinkle directly the yeast into the fermentation tank during the filling (after settling) to ensure a good homogenization. Alternatively pour the desired quantity of yeast on the surface of at least 10 times their weight of must. Gently stir to avoid lumps. Immediately transfer into the tank and homogenize the entire volume.
  • With prior rehydration and potential acclimatization: Gently pour the desired quantity of yeast into 10 times its weight of tap water at 15-37°C (59-98.6°F). Gently stir to avoid the formation of lumps. Leave it to rest for 20 minutes and incorporate the yeast starter to the fermentation tank with homogenization. Following the rehydration, it is possible to continue with acclimatization by incorporating to the yeast starter ½ of a volume of must and leave it to rest for 10 minutes. Repeat the operation until the temperature difference between the fermentation tank and the yeast starter culture is less than 10°C (50°F).
