>> this year i resolve to drink less wine and eat less ice cream but no one said anything about wine ice cream. sounds like a dream but it's the real creation of mercer's dairy in upstate new york. >> as far as we know, we're the only ones in the world making it. >> reporter: i met with the owner to find out if this idea was everything i hoped it would be. >> we pair different wines with an ice cream base and come up with an ice cream you have to be 21 to buy. >> reporter: flavors like port riesling, the ice cream winning awards worldwide. >> we have a trade secret on how we do it. basically the ice cream is a white or chocolate base. there's no other flavoring in the base. the riesling has nothing but riesling. no vanilla or anything else.
