I’ve been lucky. I’ve tasted all the above mentioned California Cabernet wines several times over the last decade. While none of these wines seemed old or the least bit tired, I am not sure any were much better or different than the day they were released. This is just my opinion, but the top California Cabernet Sauvignon do last. They re not in danger of dropping their fruit. But I am not sure they improve or gain enough complexity or nuance to warrant years of cellaring.
