Vulcan port

Vulcan port is a green alcoholic beverage made by the Vulcans. It is not intoxicating by Vulcan standards, although it can be to non-Vulcans. On Vulcan it is drunk after meals. 

In 2370, Quark and Sakonna drank Vulcan port. Quark claimed it dated from the 21st century. Sakonna was not interested in drinking the "exquisite" Vulcan port and left. After she did so, Quark took a sip if the drink, finding it unappetizing. 

In 2376, Vulcan port was served at a reception welcoming Bajoran and Cardassian delegates to Deep Space 9. Quark warned his waiters to serve it on request only, as the port was expensive.
