Yeast Propagation: Enhancing Efficiency, Flexibility, and Consistency with Frozen Liquid Yeast (FLY)
Effective yeast management is essential for producing beer of consistent quality. Traditional propagation methods, starting from slants, require extensive planning and coordination between laboratory and brewery teams. These approaches are often constrained by inflexibility and variability, which can disrupt production schedules and introduce inconsistencies into the final product. The SmartBev Frozen Liquid Yeast (FLY) format provides a novel solution to these challenges. Supplied as 1 kg frozen yeast blocks, FLY combines an extended shelf life of up to two years with high purity. As a substitute for the Carlsberg flask, FLY eliminates the need for laboratory seed train entirely, saving brewers up to 10 days in the propagation process. This innovative format offers a reliable and uniform starting point for yeast propagation, delivering higher cell counts, consistent performance, and reduced contamination risks. Industrial trials have demonstrated that FLY not only streamlines propagation but also enhances operational flexibility. Its long shelf life and ability to maintain onsite stock enable brewers to respond quickly to fluctuations in production demand. Furthermore, it supports the exploration of diverse yeast strains and even advanced propagation methods, such as fed-batch propagation. These findings underscore the potential of FLY to transform yeast management in brewing, offering both practical efficiency gains and opportunities for innovation. As such, FLY represents a significant advancement in brewing, paving the way for improved yeast handling and beer production.
