LalBrew® CBC-1™ Cask & Bottle Conditioning Yeast


LalBrew CBC-1™ has been specifically selected from the Lallemand Yeast Culture Collection for its refermentation properties and is recommended for Cask and Bottle Conditioning.

The yeast referments beer efficiently due to its high resistance to alcohol and pressure. The flavor is neutral, therefore the original character of the beer is preserved. It will settle and form a tight mat at the end of refermentation.

LalBrew CBC-1™ can be used for primary fermentation of dry ciders or mead. Maltotriose is not metabolized during primary fermentation of beer, so LalBrew CBC-1™ is well suited for sweeter fruit beers or full-bodied, malty ales.

Pitching Rate: Primary 50-100g/hL. Bottle conditioning 10g/hL.

Microbiological Properties

Classified as Saccharomyces cerevisiae, a top fermenting yeast.

Typical Analysis of LalBrew CBC-1™ Yeast:

  • Percent solids: 93% – 97%
  • Viability: ≥ 5 x 109 CFU per gram of dry yeast
  • Wild Yeast: < 1 per 106 yeast cells
  • Diastaticus: Undetectable
  • Bacteria: < 1 per 106 yeast cells

Finished product is released to the market only after passing a rigorous series of tests.

LalBrew 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 LalBrew 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 68°F (20°C) LalBrew CBC-1™ yeast exhibits:

  • Vigorous fermentation that can be completed in 3 days.
  • Neutral aroma and flavor.
  • The optimal temperature range for LalBrew CBC-1™ yeast when producing traditional styles is 68°F (20°C).

LalBrew 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 the beer. Adjust mash temperatures accordingly to achieve desired results.

Bottle Conditioning:

  • Best results are achieved when priming the beer with simple sugars such as dextrose.
  • Calculate the appropriate priming rate using the Bottle Conditioning Calculator
  • Refermentation can be completed in 2 weeks at the recommended temperatures.
  • The optimal refermentation temperature range for LalBrew CBC-1™ yeast is 59-77°F (15-25°C).
  • LalBrew CBC-1™ contains an adequate reserve of carbohydrates and unsaturated fatty acids, and cell division (typically one division) is likely to occur in the bottle.
