Lallemand is a privately owned company that specializes in the development, production, and marketing ofx000D
yeast, yeast products, bacteria, and specialty ingredients. The biofuels and distilled spirits division, and morex000D
specifically the distilled spirits team, is looking to further their knowledge on some fermentation aspects ofx000D
their strains. During alcoholic fermentation, a variety of aromatic compounds called congeners are formed. Thex000D
congeners that are produced vary depending on the strains and the conditions under which the fermentation isx000D
carried out. The mixture of all the congeners produced by a strain in a set of conditions is called a congenerx000D
profile. The final combination of congeners in the spirit will, in part, determine what flavors and aromas arex000D
imparted to the spirit. This project will aim at determining the congener profiles for a variety of Lallemandx000D
strains, in corn mash and molasses, at 25°C, 30°C and 34°C, using different yeast nutrients. These profiles willx000D
assist Lallemand in advising their clients in their choices of yeast and operation conditions.
