Bella
(BEL-93)

A versatile and robust general white strain for elegant terpenic wines.

Bella is a general white strain with an elegant and aromatic profile featuring tropical fruits and floral citrus characteristics. Bella exhibits both beta-glucosidase and some beta-lyase enzymatic activities making it release moderate levels of terpenes and some volatile thiols. This versatile strain performs well in a wide range of temperatures and it produces very low volatile acidity even during stressful fermentation conditions (including high copper residues in the must).

Guidelines

Viability / Living cells: > 1.0 x 10^10 cells /gram
Package Sizes:
500 g and 10 kg vacuum packed foil sachets.
Storage Conditions:
Store cool and dry, 4 - 15 ⁰C (39 - 59 ⁰F). Do not freeze!
Inoculation Rate:
200 - 350 g/1000 L (1.66 - 2.92 lbs /1000 gallons)

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

  1. In an inert and sterile container, prepare chlorine-free water at 38-42 ⁰C (100-108 ⁰F) that is 10 times the weight of the yeast to be rehydrated.
  2. Gently mix the yeast into the water and allow 20 minutes for rehydration.
  3. After rehydration, begin to slowly add full strength juice into the yeast mixture every 5 minutes to allow for acclimation. Do not decrease the temperature of the mixture by more that 5 ⁰C (9 ⁰F) with each juice addition.
  4. When the temperature of the yeast suspension is less than 10 ⁰C (18 ⁰F) warmer than the must to be inoculated , slowly add the yeast mixture into the fermentation vessel.

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

Applications

Bella is ideally suited for white wine vinifications but also has the ability to perform well in red wines. Bella's aromatic profile suits varietals such as Muscat, Riesling, Gewürztraminer, warmer climate Chardonnay, Semillon, Glera and it can also perform well in secondary fermentations in the bottles.

Recommended varietals include Muscat, Riesling, Gewürztraminer, Chardonnay, Semillon, and Glera.
