Cor Cor Red Okinawan Rum. Cor Cor Red and Green first seriously caught my eye at London Rumfest 2017. They were displaying at the Boutique Rumfest on the Friday afternoon. A show which is designed for new rums to display their wares to the “trade”. Its the part of the weekend I personally enjoy the most. The atmosphere is a little more restrained and you get to try a lot of new rums.
