Abstract
To prepare peach wine using peach juice, fermentation properties were monitored, and fermentation conditions (initial sugar concentration, temperature, and time) were optimized by a response surface methodology. Alcohol content for peach wine fermentation ranged from 3.4~9.2% [$R^2=0.9229$ (P<0.01)] and 8.54% (maximum value) at $18.73^{\circ}Brix$, $16.81^{\circ}C$, and 12.99 day. Acidity ranged from 0.30~0.74%, and 0.25% (minimum value) at $15.11^{\circ}Brix$, $17.09^{\circ}C$, and 13.61 day. Residual sugar concentration was $6.67^{\circ}Brix$ (maximum residual sugar content) at $17.79^{\circ}Brix$, $20.63^{\circ}C$, and 3.37 day. Yellow color intensity was 18.92 (maximum Hunter's color b value) at $13.19^{\circ}Brix$, $20.81^{\circ}C$, and 12.81 day. Based on the above study results, optimization conditions for peach wine fermentation were 9 days, below $20^{\circ}C$, and $19^{\circ}Brix$ peach juice.
