Mount Gay Black Barrel Double Cask Blend. Until pretty recent times Mount Gay were a bit of a one trick pony. They have and likely always will make their money selling truckloads of their “entry level” Eclipse rums. In particular the “Gold” variant of Eclipse as the “White” or “Silver” can be quite tricky to find here in the UK. By tricky I mean pretty much impossible. I have only ever seen it for sale once in the EU and I bought (a rather overpriced) bottle as soon as I saw it.
