Hacker Help: hanging Hutten to the wall

hutten bottle rack

Materials: Hutten, 9-bottle wine rack, solid wood

Description: I would like to hang this wine rack to the wall, but I am not sure it is possible because of the weight of the bottles. I was thinking of strengthening the sidebars with screws in the front.

What do you think?

Thank you for your help!
