1985 Groth Cabernet Sauvignon

Groth turned in a superb performance with its 1985 regular cuvee of Cabernet Sauvignon. It offers beautiful, sweet, ripe, flashy, black-cherry and cassis fruit, toasty oak, and a subtle, herbaceous note. Rich, opulent, and fully mature, this velvety-textured, explosively fruity wine should be drunk over the next 5-10 years. Given the superb performances in 1983, 1984, 1985, and 1986, I wonder why Groth's Cabernets have become so herbaceous and vegetal in recent vintages since?
