Vivace

A clean fermenting yeast for elegant, crisp, and lively white wines.

Vivace is a general white vinification strain. A good fermenter that will perform in a wide range of temperatures (14-28 °C), this strain will reveal the varietal attributes of the grapes, along with notes of pear, apple, grapefruit, lime and fresh pineapple, which will add a delicate complexity.

Guidelines

Viability / Living cells: > 1.0 x 1010 cells/gram
Package Sizes:
500g and 10kg vacuum packed foil sachets.
Storage Conditions: 
Store cool and dry, 4 - 15⁰C (39 - 59⁰F). Do not freeze!
Inoculation Rate:
200 - 350g/1000L (1.66 - 2.92lbs/1000 gallons)

Note: inoculation range is based on the juice sugar content and condition of grapes.

  1. Prepare a chlorine-free, 3:1 water to juice mixture of approximately 5 times the yeast weight at 38 - 42°C (100 - 108°F).
  2. Gently sprinkle the yeast into the water-juice mixture and, without stirring, allow 10 minutes for hydration.
  3. Stir the yeast into the water-juice mixture allowing it an additional 10 minutes to fully hydrate.
  4. Add enough juice to the yeast suspension to lower the temperature by 5ºC (9ºF). Let mixture acclimate for 5 minutes.
  5. Repeat step 4 until the temperature of the yeast suspension is less than 8°C (15°F) warmer than the must or juice to be inoculated.
  6. Slowly add the yeast mixture into must or juice.

Note: Directly adding dry yeast to the must or juice tank is not advisable.

Applications

Vivace is reommended for cool climate Chardonnays (e.g. Chablis), where pear, green plum and apple notes are desired, as well as Australian and German Rieslings styles because of its beta-Lyase activity and its citrusy (lime) characteristics. It can be a great pair for spicy Alsacian Pinot Gris or Italian Pinot Grigio as it also presents hints of black pepper, eucalyptus and sweet spice. Due to its H2S prevention and its MLF compatibility, it can be used perfectly in barrel fermentation of Sauvignon Blanc "Fume Blanc" style.

Recommended varietals include Chardonnay, Riesling, Pinot Gris/Grigio, and Sauvignon Blanc.

Notes:

Nitrogen supplementation with organic sources of nitrogen as well as DAP is recommended during the initial 1/3 of fermentation to achieve a YAN > 275, especially when fermenting at warmer temperatures.

*Grams of sugar required to produce 1% alcohol (v/v). Varies depending on the sugar and nutrient composition of the must and environmental conditions.
