Crooner Michael Bublé has been a spokesperson for Bubly Sparkling Water for a while…

And now he’s teamed up with the brand to release his own, limited-edition holiday flavor. It’s called “merry berry bublé,” and includes the flavors of raspberries, blackberries, and strawberries.

The only way to try it is to win it, and fans are asked to follow and tag @bublywater while sharing something they did this year that was naughty or nice using the hashtag #merryberrysweepstakes—you can enter through December 8th.
