This research was conducted to find out the effects of adding kefir grains at the level of 0%, 1% and 2% to quality of goat milk kefir, at room temperature for 20 h. Product qualities such as lactose, titratable acid, pH , alcohol and free fatty acid were measured. The data were analyzed using analyses of variance followed by Duncan's New Multiple Range Test. The result showed a decrease (P^0.05) of lactose and pH when the percentage of kefir grains was increased from 6.51, 4.68 , 3.71 and 4.62% , 3.55%, 3.37%, respectively. The result showed an increase (P^,05) of titratable acid, alcohol and free fatty acid at 0.17%, 1.29%, 1.42%; 0.94%, 1.88%, 2.98%; 0.86% , 3.18%, 4.41%, respectively.
