…that pack­ag­ing, which makes hav­ing a Mast Broth­ers Choco­late bar not unlike unwrap­ping a gift. The hefty paper with its fan­ci­ful designs has attract­ed as much a fol­low­ing as their dark choco­late itself. Its design­er, Nathan Warkentin, a 33-year-old for­mer menswear design­er, tries to evoke an indi­vid­ual abstract palate allud­ing to the choco­late bar’s coun­try of ori­gin. The design of the sea-salt bar, which con­tains sea salts from Maine, speaks to Amer­i­can ties and pock­et squares with its prep­py pale-blue stripes. But that’s one of the more obvi­ous. “They’re all very abstract,” says Warkentin, who cites Franz Kline, Ettore Sottsass, and var­i­ous cou­ture hous­es as occa­sion­al inspi­ra­tions. “It spins around in my head—and comes out like this.”
