Abstract

9 wine yeasts (strain numbers 101, 127, 367, 372, 373, 378, 381, 383 and 804) were examined for determining the relative amounts of metabolites: (i) % ethyl alcohol; (ii) % volatile acidity (as acetic acid); (iii) ester (ethyl acetate, mg %); (iv) aldehyde (acetaldehyde, p.p.m.); and (v) higher alcohols (p.p.m.) formed during fermentation of Bangalore Blue grapes (Vitis labrusca) having 14% total sugars, 16% Brix, acidity (as tartaric acid) 1.35%, and tannin 120 mg%. The range of values reported for these 9 yeasts are, for (i)-(v) resp., 6.0-6.2; 0.014-0.022; 21.1-40.4; 52-122; and 75-245. Among them, strain numbers 127 and 383 were found most suitable for production of wine.
