A New Zealand restaurant found a really strange signature drink to serve up to customers during the 14th annual Monteith's Beer & Wild Food Challenge, apple-infused horse semen shots.

Green Man Pub chef, Jason Varley, said the drink was proving most popular with women.

"Ladies thought it was great a couple were going to go home and get their husbands to eat grass," he said.

Men haven't been as willing to down the horse semen shots, which Varley says tastes a little like custard.

When asked about the safety of drinking horse semen, Varley added "I don't think anyone's had a particular taste for it . . . no one's addicted to it, lets put it that way."

The drink will only be available during the Beer and Wild Food Challenge. The shots aren't cheap either, $300 for 20 vials of horse semen.

Would you try it? Even on a dare?
