Posted on June 01, 2017

PETALUMA, CALIF., May, 31, 2017 -- Scott Laboratories, Inc., a leader in providing value added products for the North American wine, craft brewing and distilled spirits industries, is pleased to announce the release of two new yeast blends to their Specialty Yeast portfolio, Alchemy III & IV. The Alchemy range is a scientifically formulated blend of wine yeast strains created in collaboration with the Australian Wine Research Institute (AWRI). These yeast blends have been developed specifically for the production of New World style aromatic red wines and are formulated to provide optimum aromatic profiles.

Alchemy III
Alchemy III is a yeast blend specifically developed for complex red wines. It is a high producer of fruit and floral aromas, including 2-phenylethanol (rose), 2-phenylethyl acetate (floral and fruity), ß-ionone (raspberry) and acetate esters (fruity and candy). It produces complex wines with good structure and body, and is suitable for all red varietals.

Alchemy IV
Alchemy IV is a yeast blend that was specifically developed for the production of intense red fruit characters, such as cherry, raspberry, red currant and pomegranate. It is a high producer of ethyl esters, which contributes to the longevity of the fruit aromas. Alchemy IV is suitable for all red varietals. It produces smooth, round wines with heightened aroma intensity.

The current Alchemy range also includes Alchemy I and II, both of which were formulated for use in white wines. To learn more about the complete range of Alchemy yeast blends, see the new Specialty Yeast section on page 24 in Scott Laboratories’ 2017 Fermentation Handbook, or visit
