The launch comes as the rum category, and spiced rum in particular, continues to enjoy double-digit sales growth.
The new flavour expands on the established success of the RedLeg brand, which is growing faster than the market.
Boasting a 100% natural pineapple and caramel flavour, the spirit is made by resting in oak barrels and infused with Jamaican ginger and vanilla spices, creating a very accessible, mixable spirit.
Jade McKenzie, marketing co-ordinator at Distil, which owns the rum brand, spoke of the anticipation ahead of its release.
"RedLeg is all about relaxing with good friends," exclaimed McKenzie.
"Pineapples have long been a symbol of friendship and hospitality in the Caribbean, with islanders traditionally hanging pineapples on their doors to welcome all inside.
"Taking inspiration from this tradition, RedLeg Caramelised Pineapple is a celebration of friendship and good times."
The recommended perfect serve for the tipple is a simple pineapple and tonic, made by adding a double measure of RedLeg Caramelised Pineapple to a Collins glass with plenty of ice, a dash of gomme syrup, topped with tonic water and a squeeze of lime.
McKenzie concluded: "We expect the flavour profile to attract new consumers to the RedLeg brand and to the spiced rum category as a whole.
"As the gin boom has demonstrated, consumers are very confident about moving between flavours and styles within a popular spirits category, and RedLeg Caramelised Pineapple is the perfect reason to gather friends and explore new and great tasting cocktails.”
RedLeg Caramelised Pineapple (37.5% ABV) will be available to the on and off-trade from next month.
