Abstract:
1. A system for measuring the state or states of a fermentation cycle in a fermentation vessel for producing an alcohol-containing beverage, the fermentation vessel having a liquid therein undergoing fermentation in which at least a carbon dioxide gas is evolved into a headspace of the fermentation vessel at a rate that is proportionate to the state of the fermentation cycle, comprising: a pressure transducer measuring pressure in the headspace and providing an electrical signal therefrom representing the so-measured pressure; a stored-program microprocessor for receiving the electrical signal from the pressure transducer and logging the so-sensed pressure data and comparing the so-sensed pressure data with reference data to identify an anomalous condition including at least one of a group of anomalous conditions comprising at least a slow fermentation condition and a high-activity fermentation condition and issuing a signal to effect a corrective action increasing fermentation activity upon identification of a slow fermentation condition or to effect a corrective action decreasing fermentation activity upon identification of high-activity fermentation.
