A distributed expert system has been proposed for the monitoring of a wort
fermentation process through the flow injection determination of total acid
ity, reducing sugars, ethanol and pH. Its configuration is mainly based on
the use of distributed nodes connected by means of a network and is capable
of adapting itself to different situations. Satisfactory results have been
obtained when it has been applied in a brewery plant, important advantages
being shown over previously implemented centralized knowledge-based system
