SAFCIDER™ AC-4 SENSORY PROFILE
Intensely fresh aromatic profile (apple, floral) with a crisp mouthfeel enhancing cider structure.
Please note that those observations are based on French cider recipe trials.
Dosage / Temperature
- 10 to 20 g/hl for first fermentation
- 30 to 40 g/hl for prise de mousse
- Broad fermentation temperature spectrum: 10-30°C (50-86°F).
Use
For sweet and dry ciders from fresh or concentrated apple juices.
Suitable for difficult fermentation conditions and mixes with sugar syrups.
Rehydration procedure:
① Direct inoculation:
easy to use
Pour the yeast on the surface 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).
② 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.
Technical Characteristics
- Excellent settlement strength thanks to its 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 0.4g/L)
- Medium 2-phenylethanol and isoamyl acetate producer. High production of ethyl (fruity) esters

Storage and Shelf Life
Storage
The high rate of dry matter of our yeasts assures an optimum storage in its original packaging at a temperature not higher than 20°C (68°F) (during 3 years) and 10°C (50°F) for an extended storage (4 years).
Shelf life
48 months from production date. Refer to best before end date printed on the sachet. Opened sachets must be sealed and stored at 4°C (39°F) and used within 7 days of opening. Do not use soft or damaged sachets.
Each Fermentis yeast is developed under a specific production scheme and benefits from the know-how of the Lesaffre group, world leader in yeast manufacturing. This guarantees the highest microbiological purity and maximum fermentation activity.
