Yeast Storage and Rehydration
|
STORAGE
Dry yeast can be refrigerated or frozen
for greater stability during long term storage.
Allow cold yeast packages to reach
room temperature then rehydrate
as directed for use.

|
REHYDRATION
Dissolve the dry yeast in 50 mL
(2 oz)
of warm NOT HOT water (40°- 43°C /
104°-109°F). Let stand 15 minutes
without stirring, then stir well to suspend
all the yeast. Add to previously sulfited must.
(The yeast should not be kept in the
rehydration medium longer
than recommended.)

Gervin Active Dry Yeasts
Gervin Yeast - No. 1
: Green Label, General purpose Bordeaux (Narbonne) strain for both
white and red wines. It starts quickly, works at temperatures down to
15c and settles well at the end of the fermentation period. High
tolerance to sulfur dioxide (up to 100 ppm).
Gervin Yeast - No. 2
: Red Label, Full bodied red table Burgundy/Champagne (Monrachet).
Vigorous yeast giving a rapid start-to-finish to fermentation.

making wines from autumn fruits such as blackberries, elderberries and
sloes. It will ferment at temperatures down to 15° c. Beware of foam.
Gervin Yeast - No. 3
: Yellow Label, Sparkling, dessert, dry white table Champagne. This
wine is designed to produce sparkling wines, so it tolerates higher
levels of alcohol then most yeasts and is ideal for high alcohol dessert
wines. It is excellent for restarting stuck fermentations and will
ferment well from 12-30°c.
Gervin Yeast - No. 6 : Orange Label, High alcohol, sparkling, restarter for stuck fermentations.
Gervin Yeast - No. 5
: White Label, Quality white table wines. This French yeast is
particularly good for making quality white fruit table wines. It forms
little foam and ferments well at low temperatures (8-15° c), thus
ensuring that the wines develop excellent bouquets.
Gervin Yeast - Varietal A
: Quality red table Bordeaux SF strain. This French yeast was
selected to compliment and enhance the characteristics of the grapes.
Used for the production of red Bordeaux (Claret) wines, it ferments well
at 18-35° c.
Gervin Yeast - Varietal B
: Quality white table Rhine strain. This is another high quality
aromatic yeast intended for the production of wines with a young fruity
bouquet. Ferments down to 10° c.
Gervin Yeast - Varietal C

by many professional winemakers. Recommended for making sparkling
wines and for restarting stuck fermentations. Capable of producing
alcohol up to 18.5%.
Gervin Yeast - Varietal D
: Fruit wines from concentrates, Narbonne strain 71B. This yeast has
two inviting characteristics. First, it produces an exceptionally fine
bouquet. Second, it can metabolise up to 35% of any malic acid present
in the must, which makes this a superb yeast for many fruit wines.
