A Cuban is a type of cigar. It appeared in a deleted scene from the Star Trek: Enterprise fourth season episode "Storm Front".
The Cuban which featured in the deleted scene was in a Nazi-occupied New York City, in 1944 of an alternate timeline. The cigar was being smoked by Sal when he offered it to Jonathan Archer, referring to it as possibly "the last Cuban in the city." When Archer turned down the offer, Sal tried to persuade him to take the Cuban, saying he didn't know what he was missing, but Archer was adamant that he didn't want the cigar and replied he had "a pretty good idea" of what he was missing.
