Legacy NT 112
A Saccharomyces cerevisiae hybrid yeast for producing full bodied, structured red wines.
PURPOSE
NT 112 is recommended for the production of red wines with a firm tannic structure. We recommend it for traditional-style red wines to be aged and it is also suitable for micro-oxygenation and thermovinification.
NT 112 can produce SO2 under stress conditions, i.e. very high alcohols (> 14%) and low fermentation temperatures (< 20 °C; 68 °F).
Tasting notes
It enhances blackberry and blackcurrant aromas in Cabernet Sauvignon and red berry and minty aromas in Shiraz and Pinotage. It is also appropriate for vinifying Cabernet Franc and Zinfandel.
