Development of apple wine from Golden Delicious cultivar using a local yeast isolate.

ABSTRACT: The present study was conducted to optimize fermentation parameters for apple wine production using Golden Delicious apples. Physicochemical analysis of the cultivar revealed a °Brix-acid ratio of 24.61 with ample amount of total and reducing sugars (9.6 and 6.03% w/v); making it a suitable substrate to produce ethanol. Microbiological analysis lead to isolation of a yeast strain (namely A2) which was molecularly identified and accessed at GenBank as S. cerevisiae KY069279. Ethanol fermentation optimization using response surface methodology revealed that a temperature of 20 °C, an inoculum size of 7.08 (%v/v) and diammonium hydrogen phosphate supplementation @ 154.4 mg/100 mL as optimum for apple wine production which lead to 10.73% (v/v) ethanol production with a desirability of 8
