Sensor monitoring for dynamic propagation protocols

Higher flexibility | Consistent yeast propagations are a challenge in production environments with changing brewing schedules, downtimes, and delays. Propagation protocols that run based on a timer are not flexible. It requires additional external lab samples and labor to correct or adjust the propagation protocol. A solution is the use of inline sensors that provide accurate and reliable data to control and run the propagation according to the specifications. The Boston Beer Company (BBC) propagates various yeast strains with a “Pitch & Pull” strategy, where the propagators do not receive a CIP after multiple pitches until switching to another strain. Under these circumstances and after trialing multiple sensors, BBC successfully tested an extract sensor from Anton Paar that met all expectations and decided to move forward with the installation of these sensors for all BBC locations.
