These are made by preserving the natural charring from the original wine barrels and using it to create unique patterns. Each one is turned by hand with a unique pattern created for each piece. They feature American made stainless steel mechanisms. These pepper mills and salt shakers are made in the Napa Valley entirely from oak wine barrels retired from premium wineries in the Napa Valley. They are hand made by a 20+ yr veteran woodworker using premium joinery.
