Abstract: Raw material was sweet orange.Technological conditions for production of orange wine which used alcohol fermentation juice were studied.On the basis of single factor test，optimization of process conditions through the orthogonal experiment of fermentation for sweet orange wine was yeast inoculation 0.15%，initial sugar content 23%，fermentation temperature 30 ℃ and fermentation time 144 h.Under the optimum conditions，alcohol content of the wine was 12.8%.The wine was clear orange，fragrance and mellow.
