Thanks to its expertise in fermentative biology, Rattan can guarantee the best yields and residual sugar rates. Continuous yeast propagation, associated with a bacterial follow-up, allows the reduction of yeast consumption using standard or selected strains. Alcohol fermentation can be run in continuous mode, or in discontinuous mode when cooling water temperature is critical. Continuous Fermentation is generally proposed to facilitate operating tasks. Depending on the raw materials, recycling of yeast is realized in order to reduce Fermentation duration.
