CONTRIBUTION TO WINE

AWRI R2 is noted for its high levels of fruity yeast aromatics such as tropical fruit, grapefruit, guava, lychee and pineapple. AWRI R2 is popular for white wine making when there is need for a strong contribution of fruity aromas.

RATE OF FERMENTATION

At warmer temperatures of 18–25°C (65–77°F), AWRI R2 displays a short lag phase and strong fermentation vigour. At cooler temperatures of 14–18°C (58–65°F) this strain exhibits a medium fermentation rate. Temperatures as low as 11°C (52°F) can be used with a high quality juice/must.

NITROGEN REQUIREMENT

AWRI R2 is considered a moderate to high user of nitrogen. A nitrogen supplement is strongly recommended when fermenting musts or juice exhibiting low nitrogen levels.
