Syzgium cumini (Jamun) is an evergreen tropical tree, its various parts are known for many therapeutic properties. The present work represents the production of wines from jamun fruits using two different native isolates (Saccharomyces cerevisiae – KF551990 and Pichia gummiguttae – MCC 1273) and influence of jamun seeds on the physico-chemical parameters, chromatic properties, phenolic components and sensory attributes of wine. Wine produced was bottle aged for one year. On aging there was a reduction in bitterness and astringency. Aging lead to reduction in monomeric anthocyanin with an increase in co-pigmented and polymeric anthocynins thus affecting the wine color. Anthocyanin analysis in jamun wine indicated petunidin 3,5-diglucoside as the principal anthocyanin. PCA analysis of wine revealed association of young jamun wine with anthocyanin components. PLS analysis exhibited both positive and negative correlation between various attributes indicating sensory perception of jamun wine is affected by overall composition of the wine.
