Beginning with the 2011 vintage of our S.L.V. and FAY Estate Cabernet Sauvignons and the 2012 vintage CASK 23, a bubble code security system has been added to each 750ml format 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.
