FLYing High: Revolutionizing Yeast Propagation in Brewing
Abstract
Since the late 19th century, yeast propagation methods have evolved into a nearly universal approach, involving a laboratory seed train and brewery propagation. However, complications often arise, impacting yeast handling and production efficiency. To address these challenges, we introduce a revolutionary frozen liquid yeast (FLY) format that eliminates the need for a laboratory seed train. This format offers the benefits of long shelf-life and high purity, based on 1 kg frozen yeast blocks supplied in bags. Full-scale industrial brewing trials demonstrate consistent yeast propagation with higher cell count and faster results compared to traditional methods. By omitting the laboratory propagation, brewers can save time and better plan their operations, while also accommodating sudden needs for fresh yeast. The convenience of this product format may encourage brewers to experiment with a larger variety of yeast strains. We believe this product format could revolutionize regular propagations and serve as an ideal starting point for more experimental approaches such as fed-batch propagation.
