Stag’s Leap Wine Cellars


Verify the Authenticity of Your Stag’s Leap Wine Cellars Estate Cabernet Sauvignon.

Beginning with the 2011 vintage of our S.L.V. and FAY Estate Cabernet Sauvignons and 2012 vintage CASK 23, a bubble code security system has been added to each bottle. To verify the wine’s authenticity, each bubble tag has both a unique bubble pattern and ID code. The seal is affixed to both the glass and the capsule, and cannot be removed without visibly damaging the capsule. This additional layer of security is part of our commitment to exceptional and collectible Napa Valley Cabernet Sauvignon.

Enter the Bubble Tag’s ID code and compare the Bubble Tag on your bottle with the one on the website. You can also access the authentication site by scanning the QR code with your smartphone.
