CLEARANCE – Lallemand – CBC-1 BBF: 07/2022

Lallemand Danstar –   CBC-1 CASK & BOTTLE CONDITIONING

Microbiological Properties:

Classified as a Saccharomyces cerevisiae, a top fermenting yeast.
Typical Analysis of CBC-1 yeast:
Percent solids  93% – 97%
Living Yeast Cells  ≥  1 x 1010 per gram of dry yeast
Wild Yeast  < 1 per 106 yeast cells
Bacteria  < 1 per 106 yeast cells
Finished product is released to the market only after passing a rigorous series of tests
*According to the ASBC and EBC methods of analysis

CBC-1 is a killer yeast, meaning it will secrete a toxic protein that can inhibit killer sensitive strains (most brewing strains are killer sensitive).

While this is a positive yeast trait when conducting a pure fermentation/refermentation with CBC-1, extra care should be taken to ensure
proper cleaning procedures are in place to avoid any cross-contamination with other brews.

Brewing Properties:

Primary Fermentation

In Lallemand’s Standard Conditions Wort at
20°C (68°F) CBC-1 yeast exhibits:
Vigorous fermentation that can be completed in 3 days
Neutral aroma and flavor

CBC-1 does not utilize the sugar maltotriose (a molecule composed of 3 glucose units), and the result will be fuller body and residual sweetness in beer.

Be advised to adjust mash temperatures according to desired result
The optimal temperature for primary fermentation with CBC-1 yeast when
producing traditional styles is 20°C(72°F)

Refermentation

Best used for refermentation purpose conducted preferably with priming sugars such as dextrose.
Refermentation can be completed in 2 weeks at the recommended temperatures.
The optimal temperature range for CBC-1 yeast when refermenting is 15°C(59°F) to 25°C(77°F).
CBC-1 contains an adequate reservoir of carbohydrates and unsaturated fatty acids, and cell division (typically one division) is likely to occur in the bottle.
Temperature and inoculation rate can be adapted in order to achieve desired results. If the beer is  partially carbonated, the sugar addition can be reduced.
