Police investigator Knud Hvass says it is too early to say whether the perpetrator of the theft at the Cafe 33 bar had broken in or had used a key.
Nothing else was stolen.
Hvass said Wednesday police were notified of the theft on Tuesday.
Denmark‘s TV2 says the bottle of Russo-Baltique is made of 3 kilograms (6.6. pounds) of gold and the equivalent amount of silver with a diamond-encrusted cap.
Bar owner Brian Ingberg whose bar has 1,200 vodka bottles, told Denmark’s Ekstra Bladet tabloid that the bottle resembles a vintage car front.
Ingberg said the bottle was uninsured and on loan from a Russian businessman.
