Georg Möller owns a stake in Dömle herrgård, a manor house converted into a hotel in rural Värmland County in central Sweden.
He told the regional Nya Wermlands Tidning (NWT) newspaper that it only took five minutes of deliberation at a wine and spirits auction at the weekend for him to part with more than $28,000 for the limited edition bottle of rum.
It was developed by master distillers on Trinidad to celebrate the Caribbean island's 50 years of independence.
Only 20 bottles were produced, with Möller got his hands on the only one available on the Swedish market.
Möller told NWT he may invite master distiller John Georges at Angostura distillers of Trinidad & Tobago to come to Sweden and hold a guest lecture about the unique rum, believed to be the world's most expensive.
The Legacy bottle of rum, meanwhile, will get a specially designed cabinet at the Swedish manor house where it will be displayed rather than tasted - at least for the foreseeable future.
"If ever something really, really really unique happens, like Obama visiting us, then we'll take a sip," Möller told NWT.
