What's an onggi?

We’re named after the ubiquitous Korean fermentation vessel found in nearly every home called onggi [pronounced “ŌHNG-ghee”].

Onggi (옹기) pots carry a rich yet humble history, perfected over generations of craftsmanship using natural materials and thoughtful work. They are famous for their fermentation-friendly properties and the foods they carry are the foundation of everyday life.
