Unique. Around the world where grapes are harvested once a year, wineries produce only one vintage per year of several tons of grapes. Hatten Wines can produce many times a year since Bali's grapes are harvested every 120 days. The vines of Bali's vineyards do not have the need for a dormant period as wine vines do and every farmer prunes and harvests at different times. Hatten Wines made wine an average of 14 vintages of smaller quantities during the last 7 years.
