Arrack is a generic term used for a variety of distilled spirits that are often unrelated and can be made from different ingredients. They are found throughout East Indies—predominantly India, Sri Lanka, Indonesia, and the Philippines.
The two dominant varieties include Ceylon arrack that is distilled from fermented juice of the coconut palm and Batavian arrack that is made from molasses. The origin of arrack is vague, and though it cannot be precisely stated when and where it was exactly invented, some of the oldest references date back to the 15th century.
Although it is not clear, it is presumed that arrack originated in India, which was a result of contact with Arabic or Chinese distillation techniques. Depending on the main ingredients from which it is distilled, arrack can significantly differ in character and style.
