Clos is a new yeast strain that was recently isolated in the Priorat region of Spain. Clos was chosen for its ability to re-enforce structure while emphasizing aromatic complexity and mouthfeel. Sweet red fruit (cherry), with pepper and chocolate notes are typical of what Clos brings to a fermentation. With hot climate/high Brix fruit, Clos is a great choice for its high alcohol tolerance (17%), low Nitrogen needs and short lag phase. Clos also does well with higher fermentation temperatures (max 95 F) and shows a good compatibility with MLF. Highly recommended for Syrah, Petite Syrah, Grenache, Tempranillo and Carignane.
S. cerevisiae • cerevisiae
- Isolated by the University of Rovira i Virgili in Spain from the Priorat region.
- Notable for its high alcohol tolerance (up to 17% v/v) with a very good implantation rate in difficult conditions. Ferments over a wide range of temperatures (14-32°C/58-90°F).
- Lalvin Clos® was selected for its ability to enhance aromatic complexity, structure and mouthfeel.
- Good compatibility with malolactic fermentation.
