have a kick to it/them
1. To taste particularly spicy. In both definitions, the boldness of flavor is often unexpected or surprising. Whoa, those wings are supposed to be mild, but they really have a kick to them! Can I have something to drink? Your soup really had a kick to it!
2. To taste strongly of alcohol. Yikes, that drink has a real kick to it—I'll be drunk in another three sips!
have a kick to it
Fig. to have a strong or spicy flavor; to have a high alcohol content. I like that salsa. It has a kick to it. Tom's moonshine sure has a kick to it—don't drink too much of it, now!
