Martha Stewart's "Test Kitchen Pick" for charcoal - July 2017
Made from renewable and recycled resources--not a single tree is harvested to make Rockwood, it's only the slabs too knotty or warped to be made into lumber
Our bag is 100% natural kraft paper with soy based ink. It can be safely recyclable, composted, or burned to help light the charcoal.
