Butler's signature blend was created in collaboration with La Columbe Coffee and is a little more personal for the artist than some of the other rocker variations.

For one, the beans come from Haiti, the origin of wife Regine Chassagne's family. The country also served as inspiration for the band's last album, 2013's Reflektor.

Butler's coffee is also possibly more worthwhile buying since proceeds of the blend, dubbed "RaRa," will benefit Partners in Health and Haiti Coffee Academy.
