Mount Gay 1703 2017 release. Mount Gay probably don’t need much introduction to even the most casual of Rum drinkers. Putting aside the puerile/childish comedy that can be derived from it being a “Gay” rum, the Eclipse is omnipresent in most British supermarkets. It’s availablity in pretty much every Airport I have ever visited in Europe also ensures it is one of the Rum Worlds big hitters.
