The Aspergillus aculeatus rhaA gene encoding an {alpha}-L-rhamnosidase has been expressed in both laboratory and industrial wine yeast strains. Wines produced in microvinifications, conducted using a combination of the genetically modified industrial strain expressing rhaA and another strain expressing a ß-glucosidase, show increased content mainly of the aromatic compound linalool.Ramón Areces grant and also by the CICYT AGL2002-01906 project (Spanish Ministry of Science and Technology-FEDER)
