Type of wine:

Fermentis red wine

Red

For long ageing and fruity red wines.

SafŒno™ UCLM S377 was selected by the Castilla La Mancha University for its ability to produce very structured long ageing red wines.

Still wines. Dosage: 20 g/hl
Fermentation restart. Dosage: 30 to 40 g/hl

For Mediterranean style varieties

SafŒno™ UCLM S377 was selected for its respect of the terroir & varietal character. It allows increasing varietal characteristics of Syrah, Mourvèdre, Tempranillo and Grenache, and other sun-kissed varieties.

For premium red wines

SafŒno™ UCLM S377 gives excellent results for full-bodied but well-balanced wines. Its rather slow fermentation kinetic is very convenient for wines incurring a fermentation maceration of over 10 days allowing the wine maker to elaborate finely structured wines. Indeed, during the fermentation the progressive alcohol production is favorable to a good polyphenolic extraction.
Wines produced present an excellent ageing capacity (Tempranillo de Crianza, Cabernet Sauvignon, Syrah) and have an important volume thanks to SafŒno™ UCLM S377’s high glycerol production.

Usage

  • Gently pour the desired quantity of yeast in 10 times its weight of tap water at 30-35°C in a wide vessel. Pay attention to cover all the water surface area by creating a thin layer of yeast.
  • Leave to rest for 20 minutes.
  • Gently stir to complete yeast rehydration while avoiding the formation of lumps prior acclimatization.
  • Double progressively the volume of the yeast suspension by adding must from the tank while stirring the mix so that the temperature of the yeast starter decreases and yeast activation starts.
  • Leave to rest for 10 minutes.
  • Homogenize and incorporate the yeast starter in the fermentation tank during a pumping over with aeration.

Guarantee

The high rate of dry matter of our yeasts assures an optimum storage in its original packaging at a temperature not higher than 20°C (during 3 years) and 10°C for an extended storage (4 years). Fermentis guarantees the product complies with the International Oenological Codex until its Best Before End Date in the storage conditions mentioned above.

 

Each Fermentis yeast is developed under a specific production scheme and benefits from the know-how of the Lesaffre group, world leader in yeast manufacturing. This guarantees the highest microbiological purity and maximum fermentation activity.

Fermentation abilities:

→ Rapid fermentation start
→ 
Rather slow fermentation kinetic
→ 
Total loss of sugars
→ 
Alcohol tolerance: 14-15 % vol./vol.
→ 
Fermentation temperature: 16 to 35°C. This strain is sensitive to brutal temperature changes, it requires regular fermentation conditions.
→ 
High nitrogen requirement: In a must which available nitrogen is between 150 and 180 mg/L this strain requires at least 2 nitrogen supplies (20g/hl DAP + 20g/hl Springferm™ at yeast inoculation and 20g/hl of DAP and Springferm™ between the third and mid-fermentation.
→ 
Strong resistance to SO2

Metabolic Characteristics:

→ Sugar/Alcohol yield: 16.5 g/L for 1% vol./vol.
→ 
Low production of volatile acidity (< 0.25 g/L) and of acetaldehyde (<28 mg/L)
→ 
No production of sulfur compounds
→ 
High production of glycerol : 10 g/L
