Cough-syrupy

Cayenne hated the cough-syrupy taste of liqueur, but because she was nervous, she drank it.

The sweet reek and disgusting, cough-syrupy taste of the local plum brandy, raffia or something.

With its catchy name, addictive cough-syrupy taste (gentian root and wintergreen drove the flavor), chipper orange-and-blue logo, and kicky slogan and jingle ("Make Mine a Moxie!"), it became the nation's most popular beverage in the early 20th century.
