New York-based wine and spirits company Sovereign Brands has extended its Bumbu Rum range with the launch of an 18-year-old expression matured in Bourbon casks.The small-batch rum, called Bumbu XO, has been finished in white oak Sherry barrels from Andalusia, Spain. Bumbu XO is distilled and aged at a 120-year-old Panamanian distillery, and uses local sugarcane and pure spring water. The 40% abv expression has aromas of toffee, toasted oak and vanilla, while the palate has hints of orange zest, peppery spice and coffee. The new offering is packaged in a paperless glass bottle, with a matte black finish, silver and white details and a tarnished silver ‘X’. Bumbu XO is being rolled out to bars, nightclubs and retailers for an RRP of US$39.99-US$44.99. Earlier this month, Bumbu Rum released the second instalment of its online video series, The Bumbu Room, which stars rapper Lil Wayne answering questions about strippers, basketball and Michael Jackson. Sovereign Brands also produces Luc Belaire sparkling wine and Brazilian gin brand McQueen and the Violet Fog, which launched last month.
