Thank you for your interest in these hand crafted pieces. They are constructed from retired French oak wine barrels. The oak is seasoned for 30 months, made into a barrel and shipped to Oregon where it is used for 3-7 years to make Pinot Noir. On the back of the chairs you will find the year it was first put into wine making production and the coopers name.
The deep tones you see are those imparted by the pigment from the wine all other markings on the wood come from the hoops and daily life of the barrel around the winery. I hope that you enjoy your piece of furniture for years to come!
