Basic of cocoa bean preparation process is fermentation. Fermentation is done especially to improve and build specific chocolate flavour of cocoa bean and its products, i.e. cocoa liquor, butter, and powder; and also to decrease the disliked flavors, like bitter and acid. Research of cocoa bean fermentation was hold on in Subak Abian Pucaksari, Tabanan. This research involved 20 cooperative farmers with 0,5 hectare farm area per each farmer. The treatment used was time of cocoa bean fermentation, i.e. without fermentation, not fully fermentation (4 days), and fully fermentation (5 days). Variables abserved were dried cocoa bean's physic and chemical quality, and also cocoa product's chemical and organoleptic quality. Organoleptic test done to cocoa liquor and powder was descriptive and ranking test used 15 semi-trained panelists. The ersult showed that the fermentation process had significant influence to dried cocoa bean's chemical quality and its products. Fermentation had no significant influence to dried cocoa bean's physic quality. For organoleptic quality attributes, all panelists gave the highest rank for cocoa liquor and powder prepared from fullyfermented cocoa bean.
