A visit to North Bali will take you to vast planted areas where the vines are trained into an overhead trellis called Pergola and where posts consist of small trees. Besides keeping the workers shaded, this system reduces the risk of diseases and sunburn on the grapes, contributing to a better grape quality. The tropical climate of Bali makes for the unique character of winemaking in Bali: grapes are harvested year-long from evergreen vines and wine can be produced in several vintages per year instead of the traditional yearly vintage production of other wine areas. Hatten Wines has the privilege to buy its Alphonse-Lavallée grapes from several growers but has its own vineyards for the Belgia white grapes, a Muscat grape family member.
