Yield is an independent design house which is really trying to place itself within a distinctly American manufacturing tradition. In fact, they chose St. Augustine, Florida, as a home for their operations, a town which lays claim to being the oldest city in the USA. Symbolically, it's a very powerful location, and the team, started by designers Andrew Deming and Rachel Gant, have sought to combine local craft tradition with a more global aesthetic sensibility.
Their products range from bags and accessories, to homeware and jewelry. Everything they do captures that blend of tradition and modern, minimalism. The copper cup is a perfect example. Copper has been used by humans for thousands of years. Thanks to its natural antimicrobial properties, it's the perfect material for kitchenware. The cup is also pretty much hand-made, and as such, tends to have little imperfections and variations that make it as unique as it is functional.
