Presentation Abstract Top-fermenting yeast have a wide variety of fermentation properties, which strongly influence the flavor and taste of beer produced. We have investigated the fermentation properties of more than 200 strains of top-fermenting yeast by lab-scale fermentation analysis. The yeast strains were grouped by multivariate statistical analysis into clusters based on several [...]

Presentation Abstract The occurrence of mitochondrial mutations in brewing yeast (i.e., petites) has been noted since before the mid-1900's. Relatively recent work has reported on the occurrence of these mutants in large-scale cylindrical-conical fermenters. It has been generally accepted that elevated temperatures and ethanol levels in the centre of the fermenter cone contribute [...]

Presentation Abstract Coopers Brewery Ltd (Coopers) employ a Manufacturing Execution System (MES). MES is a software system that integrates the management system (JDE) to the plant floor (control). The main goal of the MES implementation was to increase process reliability by providing complete visibility over production processes and to provide error-free electronic supply [...]
