A welcome outcome from the now decade-long focus on authentic craft cocktails is that many obscure ingredients from dusty cocktail books are now available on store shelves and backbars. American spirits importer Haus Alpenz has been particularly instrumental in reviving obscure ingredients, including Batavia Arrack Van Oosten, an older sibling to Caribbean rum. However, in the decade since its release, the Van Oosten’s unusual, raw funkiness hasn’t led to its widespread adoption. Thus, I was recently surprised to see another importer bring a second Batavia Arrack into the U.S. Having tasted and used this new expression from By the Dutch, it’s a very different animal and worth a fresh look. Before jumping to tasting notes and recipes, let’s dig in to a bit of Batavia Arrack history to set the stage.
