The potential of wine production from guava is presented in this review. Guava is easy to culture, posseses high nutritive value and its products like juices, beverages, nectars etc. are largely appreciated by the consumers. Guava juice requires ‘chaptalization’ so as to adjust its Brix and prepare a perfect wine out of it. The chaptalized juice (“must”) is treated with pectinase or a combination of enzymes and fermented with traditional yeasts at a temperature range of 22 to 30°C and inoculum size of 6 to 11% (v/v). The addition of N and P improves ethanol production and quality parameters of guava wine. Racking and ageing of guava wine also improves the sensory and organoleptic characteristics of guava wine.
Key words: Guava, Saccharomyces cerevisiae, Brix, inoculum size, temperature, DAHP supplementation.
