Alchemy III

A Saccharomyces cerevisiae yeast blend for complex red wines.

APPLICATION

Alchemy III is for the production of complex red wines. This blend is a very high producer of 2-phenyl- ethanol (rose), 2-phenylethyl acetate (floral and fruity), ß-ionone (raspberry) and acetate esters (fruity and candy). Common to both Alchemy red blends is their very high contribution to fruit aromas 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 characters). Alchemy III produces complex wines, with good structure and body and is suitable for all red varietals.

Science and Technology

Product Anchor Alchemy III et IV image — Blend 1, 2 and 3 contain the exact same three yeast strains, with only the ratio of individual strains in the blend being different.

Origin

Alchemy III is a scientifically formulated blend of wine yeast strains. It has been developed in collaboration with the Australian Wine Research Institute (AWRI). These yeast blends have been formulated to provide optimum aroma profiles.
