Anchor Alchemy IV is a scientifically formulated blend of wine yeast strains. It has been developed in collaboration with the Australian Wine Research Institute (AWRI). These blends have been formulated to provide optimum aroma profiles.
Anchor Alchemy IV is for the production of intense red fruit characters (cherry, raspberry, red currant and pomegranate) in wines. This blends is a very high producer of ethyl esters, especially of ethyl hexanoate (fruity), which contributes to the longevity of fruity aromas. This makes it very suitable in ageing wines that keep their intense red fruit characters. This blend also has significant production of total esters and terpenes (fruity and violet). Common to both Anchor Alchemy red blends is their very high fruit contribution due to higher total esters and ethyl hexanoate production. This is further enhanced by ß-damascenone (violets and a decrease in methoxy-pyrazines (which can mask fruit character). Alchemy IV produces wines with significant aroma intensity that are rounded and smooth and is suitable for all red varietals.
It is recommended for vinifying white grape varieties such as Sauvignon blanc, Colombard, Chenin blanc and Verdelho.
