Racy.

Having distinctive piquancy, as racy wine. It was first applied to wine, and, according to Cowley, comes to us from the Spanish and Portuguese raiz (root), meaning having a radical or distinct flavour; but probably it is a corruption of “relishy” (French, reléché, flavorous).

“Rich, racy verse, in which we see

The soil from which they come, taste, smell, and see.”
