This work aimed to evaluate the physical-chemical and acceptance of sugarcane spirit produced with juice originated from different preparations of organic sugarcane. It was used the sugarcane variety RB867515 in the following treatments: A = crush of sugarcane with straw and bark, B = crush of sugarcane without straw and with bark, C = crush of sugarcane without straw and bark, and D = crush of sugarcane internodes without straw and bark. The distillate of sugarcane spirit was produced at the Laboratory of Organic Agriculture and Foods in the Center for Agricultural Science (CCA)/Federal University of São Carlos (UFSCar) situated at Araras, São Paulo State, Brazil. The fermentation of juice was developed in four fermentation vessels of stainless steel plates with 1000L capacity (each one fermentation vessels received the juice from treatments) using industrial yeast (8g / L) for each one. Were measured the following physical-chemical properties: total acidity, esters, aldehydes, higher alcohols, methanol, cupper and pH. The distillate were evaluated for color, aroma, flavor, body and overall impression, using sevenpoint hedonic scale ranging from "really liked" to "dislike very much." Data were analyzed using analysis of variance and Tukey's test to verify differences between the means (p ≤ 0.05). The results of acceptance tests and physicalchemical analysis showed that the sugarcane spirit with better acceptance among consumers was that one produced from sugarcane without straw and with bark, and the sugarcane spirit with the lowest acceptance was that one produced from the juice extracted from the internodes.
