Ktarian Merlot

A bottle of Ktarian Merlot

Ktarian Merlot was a dry red wine produced by the Ktarians.

During a romantic dinner in 2374, Tom Paris and B'Elanna Torres shared a bottle of Ktarian Merlot from 2282. (VOY: "Scientific Method")

Close examination reveals that the logo of Ktarian Merlot, barely glimpsed on the glass bottle, is a re-use of the logo of the Akritirian species.
According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 446), this wine was similar to Earth's Saint-Émilion wines. The merlot was made from the fermentation of black Ktarian grapes.
