Fermentis AS-2 cider yeast

Description

The best cider yeast for a fresh aromatic profile (apple, citrus) with nice elaborated fruit notes (applesauce) bringing a good overall complexity.

Usage:
For sweet and dry ciders, even under difficult fermentation conditions. Sweet and round mouthfeel.

Technical Characteristics:

  • Very good settlement strength even with its sensitive to killer phenotype
  • Regular to 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
  • Good assimilation of fructose
  • Maximum initial SO2 level recommended: 100mg/L and low production of acetaldehyde and SO2
  • Medium malic acid consumption (up to 0.9g/L)
  • Medium 2-phenylethanol and ester producer. Good balance between acetate (amylic) and ethyl (fruity) esters

Dosage:
10 to 20 g/hl for first fermentation

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.
