Batavia Arrack is a type of rum distilled in Indonesia from sugar cane and a small portion of local red rice which is used to start fermentation. It is pot-distilled, and is strongly aromatic, with a buttery, musky aroma.
Batavia Arrack was popularized in Sweden in the mid-18th century as the Swedish East India Company developed a trade route between Indonesia and Sweden. Batavia Arrack is used to make punsch, a warming drink with added sugar and flavorings.
Punsch was also popular in America pre-Prohibition, but like many types of alcohol, was lost, and is only now being imported into the United States by Haus Alpenz under the van Oosten brand. Many punch recipes from Jerry Thomas called for Batavia Arrack as an ingredient.
