Ayem-Sud wine

Ayem-Sud wine was an alcoholic beverage produced by the Yemai people of planet Sigma Niobe II. Though not a true wine, it was nonperishable and able to be carried on long sea voyages without need for refrigeration. Leonard McCoy became very fond of Ayem-Sud wine during his stay on Sigma Niobe II, and had considered how to bring the greatest amount possible with him aboard the USS Enterprise (NCC-1701) without violating the Prime Directive.
