James Suckling reviewed the 2015 Ultimate Red on December 21, 2017:

92 points: A clean and bright red with currant, blueberry and mineral character. Medium to full body, bright acidity and fine tannins. Fresh finish. Delicious now. A blend of 74.9% cabernet sauvignon, 12.1% cabernet franc, 11.2% merlot, 1.8% malbec. Always delicious.
