The Bottle Grinders, Set of 2 release salt, pepper, or other seasoning in a controlled line at the base, leaving the counter and the grinder itself clean after each turn. Each grinder is shaped like an ordinary bottle and used upside down, with a ceramic milling mechanism inside adjusted from coarse to fine by twisting the wood cap at the top. Norm Architects designed it for Audo Copenhagen, playing on the mismatch between a bottle's usual liquid contents and its actual job as a spice mill.
