The 2013 Cabernet Sauvignon Cask 23 is backward, but concentrated, with beautiful blue, red and black fruits, spring flowers, a touch of toasty oak, relatively noticeable tannin and a full-bodied, multi-layered mouthfeel. This is coiled tight compared to the 2012, but has fabulous upside potential. Forget it for another 3-4 years and drink it over the following 25-30 years.
