Old monk rum is a Indian rum classified as dark rum. It has a distinctive vanilla flavor and is one of the largest selling rums not only in India but in the rest of the world, almost all thanks to word of mouth. It's sweet but not sugary, oaky but not woody, and flavorful while still mellow.
It can be served with soda or just water and would also go well with some vanilla ice cream or even pancakes. It is also said to have medicinal qualities e.g. You can use 60 ml Old Monk Rum with warm water and it will help to get relief in cough and cold and give a sound sleep.
