YEASTER
TF are dehydrated dry yeasts composed by a strain of Saccharomyces cerevisiae
selected and approved by the LIEC entity, with a specific application
for the production of balanced young red wine.
The vintage that is the
priority object for its utilization is that with whom it is intended to get red
wine with an aromatic typicity reinforced with fruity tones, and a balanced polyphenolic
composition (colour and tannins), as in traditional vinifications as in carbonic
macerations.
The utilization of YEASTER TF carries out the basic
technical objective of an optimum development of alcoholic fermentation, which
is characterized by minimal nutritional requirements of yeasts, a short latency
stage, a regular evolution of the process and a high fermentative potential; and,
in parallel, a minimum generations of volatile acidity, acetaldehyde and sulphide.
It also adds in this case, a significant generation of characteristic fruity secondary
bouquets, the possibility of fermenting in low temperatures (15ºC) and an increase
of the extraction of the grape phenolic fraction .
Use Conditions
The
optimum dose is 20 g/Hl. Its correct use must be made in three consecutive stages:
Rehydratation.
Add 10 l. of water in a container, preferably hot and without chlorine, 4 l. of
must or 500 g. of sugar; homogenize it and check that the temperature is between
35 and 40ºC. Add 1 kg of yeasts, leave it during 10 minutes without homogenizing
and subsequently, stir it very slowly dissolving lumps smoothly. Let it settle
until the appreciable appearance of froth and characteristic odour is detected.
Acclimatization. In the case of significant thermal
gradients, add gradually must to the previous suspension, checking that between
every addition the active fermentation is produced until a maximal temperature
difference with the must objective of 5ºC.
Incorporation. The
addition of the previous starter must be made pursuing the maximum homogenization
and aeration of the element.
