Caribou Coffee is being co-branded with Einstein Bros. Bagles beginning with the opening of a new co-branded store in Colorado Springs on Wednesday.  Both entities are owned by private-equity firm Joh. A. Benckiser Group.  The German conglomerate plans to open 20 of the newly co-branded stores this year split with half being conversions and the other half new openings.  Caribou has experimented with co-branding in the past, as recently as 2013 joining with Bruegger’s Bagles.  They will keep the 8 existing joint locations with Bruegger’s.  Benckiser Group, which purchased Caribou in 2012 and Einstein Bros. last year, also bought Peet’s Coffee & Tea back in 2012 as well.
