Brennivín is a traditional Icelandic spirit, often referred to as "Black Death." It is made from fermented grain or potato mash and flavored with caraway seeds, giving it a distinct taste. The drink is typically around 37.5% alcohol by volume and is known for its strong flavor and aroma. Brennivín is commonly served as a shot and is often enjoyed with traditional Icelandic foods, such as fermented shark (hákarl). It has become a symbol of Icelandic culture and is frequently featured in local celebrations and gatherings.
