Influence of immobilized yeasts on aroma profile of Rose Muscat of Poreč and Muscat Blanc distillates

In this research main goal was to investigate influence of immobilized cell fermentation on aroma of distillates produced from two grape varieties commonly grown in Croatiian region Istria (Rose Muscat of Poreč and Muscat Blanc). Distillate samples were produced both by classical and immobilized yeast technology. Aroma profile was determined using GC/FID analysis. Results showed that immobilized cell technique gives distillates with higher ethanol and lower ester contents. The immobilized cell technique seems to be promising technique for production of quality marcs distillates.
