General Description

Most notably used in the production of nouveau style wines, BrewersDIY Dry Mead Yeast  owes its success to being able to produce amyl ester, which reinforces the aromatic profile of wine. This yeast is highly recommended for white wines, rose and red wines, but can also be used in mead production.

Characteristics

This yeast producesamyl ester, which reinforces a wine’s aromatic profile.

This yeast has an alcohol tolerance of around 14% ABV (May vary)

Does not include yeast nutrients.

Fermentation Guidelines

The optimal fermentation temperature for this yeast is around 15 - 30°C

Though fermentation temperatures below and above this temperature range are possible, lower fermentation temperatures will produce a slower rate of fermentation, and even stagnation below 14°C while higher fermentation temperatures will produce a higher rate of fermentation but at a gradual increase of ester production.

It is recommended to use a pitching rate of 0.2 – 0.5g yeast p/L of wort.

Can be pitched either directly or after rehydration.

Direct pitching

Pitch the yeast directly in the fermentation vessel on the surface of the wort at or above the fermentation temperature.
Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available to avoid clumps. Ideally, the yeast will be added during the first part of the filling of the vessel; in which case hydration can be done at wort temperature higher than fermentation temperature, the fermenter being then filled with wort at lower temperature to bring the entire wort temperature at fermentation temperature.

With prior rehydration

Alternatively, sprinkle the yeast in minimum 10 times its weight in sterile water 25 - 29°C. Leave to rest 15 to 30 minutes, gently stir and pitch the resultant cream into the fermentation vessel.

Storage

For less than 6 months: the product must be stored below 24°C. For more than 6 months: the product must be stored below 15°C.  For short periods not exceeding 7 days there is an exception to these rules.

Shelf life

36 months from production date. Refer to best before end date printed on the sachet. Opened sachets must be sealed and stored at 4°C and used within 7 days of opening. Do not use damaged sachets.
