Description
-
High Tolerance: Withstands up to 18% alcohol and high SO₂ levels, making it ideal for secondary fermentation or restarting stuck batches.
-
Neutral Flavor Profile: Low H₂S and minimal ester production deliver clean, true-to-fruit aromas in wines, ciders, and meads.
-
Vigorous & Efficient: Fast-fermenting with low nutrient requirements, performing reliably in low temperatures (50-86°F).
PM16 is a typical Prise de Mousse yeast from Champagne region (France). This yeast is robust, low-nutrient-requirement and high-alcohol-tolerance strain for white wine, sparkling wine, late-harvest wine, also cider and mead. The H₂S production of PM16 is low, and the fermentation is vigorous to produce a dry wine with clean and neutral aroma, especially for Chardonnay with subtle pear, citrus like flavors. PM16 has a good tolerance for SO₂ and high alcohol level, so it is very recommended for restarting stuck fermentation. With the good characteristic of fermenting in low temperature, it also used in sparkling secondary fermentation. PM16 has rapid fermentation rate with short lag time. PM16 has neutral contribution to wine's organoleptic profile (low production of esters), makes it ideal for producing different types of red, white and fruit wines.
Fermentation Characteristics
- Fermentation temperature range: 50-86°F (10-30°C)
- Alcohol tolerance: around 18%vol
- Nitrogen requirement: low
- Fermentation speed: fast
- Production of volatile acidity: low
- High tolerance of SO₂
- Production of SO₂: moderate
- Production of H₂S: low
- Production of foam: low
- Production of glycerol: moderate
- Flocculation: very good
Application
A wide range of applications for different types drinks, including wine, cider, mead and other fruits. Suitable for secondary fermentation for sparkling wine with short lag phase. Suitable for restarting fermentations, low temperature fermentations, and high clarified, low nitrogen and growth factors musts. A pure yeast selected for medium aromatic characters and robust fermentations. The fermentation kinetics of PM16 is complete and robust with clean varietal aromas without undesirable compounds. Good fermentation activity in the conditions of nutrient deficiency or high potential alcohol content. Low production of H₂S makes wine clean. Neutral sensory for wines to preserves the varietal properties.
Protocol for Use
1. Rehydration Without Yeast Nutrition
Dosage: 20 to 40 g/hL
Rehydrate the yeast using water at 10 times its weight, with a temperature range of 95°F to 104°F (35°C to 40°C).
Resuspend the yeast by gently stirring, and wait for 20 minutes.
Blend the rehydrated yeast with a bit of juice/must, gradually acclimating the yeast suspension temperature to within 5-10 degrees of the juice/must temperature.
Inoculate into the juice/must.
2. Rehydration with Nutri-Rehyd
In the situations of tough fermentation conditions (high potential alcohol, over clarified must, low temperature), rehydrating yeast with Nutri-Rehyd is recommended. Carry out the rehydration procedure according to the selected Nutri-Rehyd product's instructions.
Storage and Shelf Life
Store in original sealed packages, in a cool and dry environment. Shelf life at the recommended conditions is 42 months. After opening the yeast must be used as soon as possible. Avoiding long-term storage at temperature above 86°F (30°C).
Tips
The difference between the yeast and must temperatures should not exceed 10 degrees during inoculation.
Fermentations using active dry yeast can reduce the risk of contamination by wild yeast and harmful microorganisms.
The rehydration process must not exceed 30 minutes.
