When it may not be suitable

How to use
To prepare the yeast, dissolve the contents of the 7g sachet in approximately 100ml of lukewarm water at a temperature of about 25-30°C. Allow the mixture to stand for 20 minutes, stirring occasionally to ensure the yeast is fully rehydrated. Once activated, add the yeast suspension directly to the prepared grape must. Ensure that the fermentation vessel is kept in a stable environment within the recommended temperature range to facilitate optimal yeast activity throughout the process.
What to consider before purchase
Ensure your grape must is prepared and adjusted for acidity before adding the yeast.
Verify that your fermentation equipment is properly sanitized.
Check that the volume of your must is appropriate for the 7g sachet dosage.
Usage recommendations
For the best results, maintain a consistent fermentation temperature between 20°C and 25°C and ensure the must is free from excessive preservatives that could inhibit yeast growth.
