Abstract: The wine parameters of tropical fruit wines, distilled wines and tuba stored in plastic-low density polyethylene (LDPE), amber glass and colorless glass bottle kept in room temperature (average was 28⁰C) and cold temperature (average was 4⁰C) were determined after storing the wines for 94 days. The wine parameters that were monitored were pH, titratable acidity, volatile acidity, ethanol content, methanol content, total soluble solids and total plate count. The tropical fruit wines were influenced by the temperature and container in terms of pH, titratable acidity, ethanol content, and total soluble solids while the volatile acidity was affected by the container only. There was an increase in the pH and ethanol content when the wines were stored in cool temperature and amber glass bottle, the titratable acidity and total soluble solids increased when stored in room temperature and plastic container and the volatile acidity increased while stored in plastic container regardless of the temperature. The distilled wines were influenced by the container and temperature in the volatile acidity, ethanol content and total soluble solids only, the other parameters were not affected during the storage. The volatile acidity and total soluble solids increased when stored in room temperature and plastic container while the ethanol content was higher when stored in cold temperature and amber glass bottle. Tuba was affected by the temperature and container in terms of pH, titratable acidity, volatile acidity, ethanol content and total soluble solids. The titratable acidity and volatile acidity were higher when stored in room temperature and plastic bottles while the pH, ethanol content and total soluble solids were higher when stored in cold temperature and amber glass bottles. The changed in the wine parameters during the storage study contributed to the wine spoilage, the proposal given to the wine manufacturers discussed how the change will be addressed.
