The Courtier California St. Helena Sauvignon Blanc 2025 is a $12.99 Costco wine. This is a negociant wine.
The Story

A Negociant is a wine company that purchases surplus wine from a winery and sells that excess under its own label and does not reveal the name of the winery.
These wines are sold at a discount from the winery’s bottling, so secrecy is necessary not to hurt the sales of the original wine.
The front label of the Courtier California St. Helena Sauvignon Blanc 2025 even says ‘non-disclosure agreement”.
Except in this case, where the California Wine COLA registry names Charles Krug/Mondavi in St.Helena as the winery of record.
Charles Krug is the oldest winery in Napa Valley, dating to the 1860s, and has been controlled by Robert Mondavi Winery for decades.
A quick check of the web shows Charles Krug offering an estate-grown St.Helena Sauvignon Blanc which lists for $23, though is often found around $15.
Charles Krug does not show a release of a 2025 vintage estate Sauvignon Blanc.
The Coutier California numbers the bottles; mine is 45495, which is 152 barrels, though there is probably more bottles.
The alcohol content is 13%.
