The concentration of pectinase at and 1 were conducted to make the clarity KEYWORDS of soursop wine. Besides the storage conditions were performed at room temperature 28 30 C and cool temperature 2 4 C with the Annona muricata corresponding time at 2 4 and 6 months to investigate the stability of Pectinase color pH ºBrix and ethanol content. This study determines a rate of Preservation pectinase capable of making soursop wine and also give good sensory evaluation results for clarity color smell and taste at Soursop by the optical transmittance of 450 nm. The results also show that wine Soursop wine was stored at cold temperature 2-4 C more preferred over storage at room temperature after 6 months. The pH value ºBrix and ethanol content v v were stable at the cold temperature storage. However these indices decreased when stored at room temperature while ºBrix was stable under two storage conditions.
