• AC-4 is ideal to produce fresh and crisp cider
• Intensely fresh aromatic profile (apple, floral) with a crisp mouthfeel enhancing cider structure
• Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world

The best cider yeast for an intensely fresh aromatic profile (apple, floral) with a crisp mouthfeel enhancing cider structure.

Usage:
For sweet and dry ciders even under difficult fermentation conditions.

Technical Characteristics:

• Excellent settlement strength even with its sensitive to killer phenotype
• Fast kinetic
• Broad fermentation temperature spectrum: 10-30°C (50-86°F)
• Low nitrogen requirements: Ratio YAN**(mg/L)/Sugar(g/L) > 0.7 – 0.8
• Very good assimilation of fructose
• Maximum initial SO2 level recommended: 75mg/L
• Very low malic acid consumption (less than 0.4 g/L)
• Medium 2-phenylethanol and isoamyl acetate producer. High production of ethyl (fruity) esters

Dosage:

• 10 to 20 g/hl for first fermentation
• 30 to 40 g/hl for prise de mousse

Direct inoculation:

• Pour the yeast on the surface of at least 10 times their weight of must (possibly directly on the top of the tank or during tank filling after clarification).
• Gently stir to avoid or break clumps.
• Immediately transfer into the tank via a pumping over with aeration (or homogenize tank volume).

With prior rehydration:

• Pour the yeast on the surface of 10 times their weight of tap water at room temperature.
• Gently stir to avoid or break clumps.
• Wait for 20 minutes and transfer into the tank via a pumping over with aeration.

Shelf Life
4 years from production date.
