Lallemand CBC-1 Cask and Bottle Conditioning Yeast 11 Gram

SKU: 599850V Category:

LalBrew CBC-1™ has been specifically selected from the Lallemand Yeast Culture Collection for Cask and Bottle Conditioning applications due to its high resistance to alcohol and pressure. LalBrew CBC-1™ has a neutral flavor profile and does not metabolize maltotriose, therefore the original character of the beer is preserved after refermentation. The yeast will settle and form a tight mat at the bottom of the bottle or cask. LalBrew CBC-1™ is also an ideal strain for primary fermentation of dry ciders, mead and hard-seltzer. For simple sugar fermentations with appropriate yeast nutrition, LalBrew CBC-1™ achieves high attenuation with a clean and neutral flavor profile.

Classified as a Saccharomyces cerevisiae, a top fermenting yeast.

  • Finished product is released to the market only after passing a rigorous series of tests
  • *According to the ASBC and EBC methods of analysis

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 CBC-1, extra care should be taken to ensure proper cleaning procedures are in place to avoid any cross contamination with other brews.


LalBrew CBC-1™ has a neutral flavor and does not metabolize maltotriose, so the characteristics of the beer are not altered during bottle conditioning. Best results are achieved when priming the beer with simple sugars such as dextrose. Using a pitch rate of 10g/hL, refermentation can be completed in 2 weeks at the recommended temperatures. The optimal refermentation temperature range for LalBrew CBC-1™ yeast is 20-30°C (68 – 86°F). 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.

LalBrew CBC-1™ produces high attenuation with neutral flavor and aroma in cider, mead and seltzer fermentations. Nutrients should be added to the fermentation to ensure appropriate levels of nitrogen, vitamins and minerals. LalBrew CBC-1™ is not recommended for primary fermentation of beer. The optimal fermentation temperature range for LalBrew CBC-1™ yeast is 20-30°C (68 – 86°F). The total fermentation time will depend strongly on the type of fermentation, pitching rate, nutrient composition and fermentation temperature.
