The 2015 Walla Walla Cabernet Sauvignon opens in the glass with a lovely bouquet of crushed blackcurrants, dark plums, mocha and a subtle framing of expensive new oak. On the palate, it's medium to full-bodied, layered and richly tannic, with good energy to its crunchy core of nicely concentrated fruit and a youthfully chewy, fine-grained finish. The tannic fist of the vintage does make itself felt, but by no means as assertively as in the 2015 Sangiovese. So, while this is never going to be the most elegant vintage of the Leonetti Cabernet Sauvignon, it should reward 2 or 3 years in the cellar and drink well for a decade thereafter.
