The locals drink two kinds of alcoholic beverages: Lugdi plains or Chang Himalayan, a kind of crude beer made from fermented rice or barley and Sharab plains or Arak Himalayan, an alcoholic drink distilled from Lugdi/chang. Arak can also be made from jaggery or apples or any other fruit.
It might be an interesting experience to visit a local home when the ladies make arak quite regularly. You can sit in the fields where the ladies make it, have hot water from the distilling to wash with and "test" the product at frequent intervals.
