Danish company Chr. Hansen, with headquarters on the outskirts of Copenhagen, is one of the major suppliers to the wine industry. The vast majority of wines ferment with cultured yeast (or “selected”) and often this yeast comes from Chr. Hansen. The company continually experiments to offer different types of yeast to wine producers. 2009 it launched Prelude, the first cultivated yeast without Saccharomyces. Prelude contains 100% Torulaspora delbruecki, a wild yeast that is naturally present in the must.
Chr. Hansen also offer yeasts that produce lower alcohol, lactic bacteria to quickly get the malolactic fermentation started and much more to facilitate a winemakers life. Read more about Chr. Hansen interesting research on Meininger.de.
