Montpellier, France. Anchor Exotics SPH is the world's first non-genetically modified hybrid between Saccharomyces cerevisiae and Saccharomyces paradoxus (SPH). It has the benefits of wild yeast without the risks that natural fermentation is sometimes associated with. This strain ensures complete fermentation, facilitation of malolactic fermentation (in red winemaking), up to 15 g/l glycerol production and, most importantly, allows winemakers to produce full-bodied complex wines.
Winemaking trials conducted with Exotics SPH in France and South Africa revealed exceptional results. In tastings of Syrah wines in France, Exotics SPH was the tasters' preferred yeast, delivering a well-balanced, complex, round wine. They described it as a yeast suitable for the production of 'cuvée' and single vineyard wines.
Compared to S. cerevisiae commercial strains, Exotics SPH also has the ability to partially break down malic acid, thereby substantially increasing the speed of bacterial malolactic fermentation (MLF). This crucially important attribute enables the quick processing of wine and also protects against microbial spoilage (for example, from Brettanomyces). Exotics SPH facilitates the speedy completion of the MLF process.
In addition, in high grape-sugar conditions, the yeast produces significantly more glycerol and less alcohol than most commercially available strains. In trials, Exotics SPH fermented South African Pinotage with a level of 15.5% alcohol to a dry wine with ease.
Due to its moderate fermentation speed, Exotics SPH has also been used successfully in South Africa to produce barrel-fermented white wines (Chardonnay and Chenin Blanc).
Winemakers describe the resulting wines as having a complex, exotic bouquet with a very pleasant mouthfeel. This new world wine yeast strain, brought to you by OENOBRANDS offers winemakers the opportunity to create wines with increased complexity in controlled conditions.
