Abstract

For over 30 years the use of immobilised yeast for sparkling winemaking has been widely tested and discussed amongst the scientific community [1, 2, 3]. The main advantage of immobilized yeast for sparkling winemaking is the suppression of the riddling step which requires costly equipment that takes up a lot of space in the wineries. In spite of all the academic work and potential industrial interest very few processes have successfully passed from the laboratory into an industrial scale. Proenol together with the Laboratoire de Génie Chimique de Toulouse developed an industrial immobilization process using the vibrating nozzle technology. In this process the yeasts are immobilized in double layer beads made of calcium alginate and afterwards are dried in order to increase the shelf-life. The objectives of this work were to evaluate the fermentative performance of the active dried encapsulated yeast in different base wines and to make a comparative study with the fermentation with the free cells.
