The developed method was applied for yeast age control in traditional batch and continuous beer fermentations. At the pitching rates used in industrial beer fermentations, our results support former findings by locating a gradient of increasing yeast age from the top to the bottom zone of the fermenter cone. The results also indicate that in continuous beer fermentation, the increasing bud scar fluorescence of immobilized Cells Could help to schedule the replacement of aged biomass, prior to loss of viability or deterioration of process performance and product quality
