DIAMOND & KEY
Diamond & Key is owned by Klay Thompson of the Golden State Warriors, along with St.
Louis Cardinal third baseman, Nolan Arenado and their friend and financial advisor, Joe
McClean. Klay’s interest in wine began in 2017 after wildfires devastated areas in Napa and
Sonoma and he teamed up with the North Bay Relief Fund to raise money to help with the
area’s recovery. It was in that time that he met their future winemaker, Joe Harden, current
winemaker at Nickel & Nickel in Oakville. Joe sourced Panek Vineyard Cabernet through
Thomas Brown and made the first vintage of Diamond & Key at the Nickel & Nickel facility.
175 cases of premium, vineyard designate Cabernet.
