Product details

Lalvin Clos® was selected by the University of Rovira i Virgili in Spain from the Priorat region, situated in the province of Tarragona. Vinification trials show Lalvin Clos® has a very good implantation rate under difficult conditions, such as low nitrogen content over a wide range of temperatures. The results of experimental and winery trials with Carignan, Grenache, Syrah, Zinfandel and Tempranillo grapes confirm this yeast’s potential as an excellent tool to enhance aromatic complexity, structure and mouthfeel.
