In some years, the Insignia blend contains well over 75 percent cabernet.

Whether this was true is open to debate, but nowadays, many Carmignanos are up to 20 percent cabernet.

Previously, the best Californian wine makers had boasted that their wine was 100 percent cabernet.

The law says a wine must contain 75 percent cabernet to be called a cabernet.

If it isn't 75 percent cabernet, you can't call it cabernet.

As with the 100 percent cabernet, Mr. Tchelistcheff's ideas have changed over the years.

Some of California's best cabernets continue to be 100 percent cabernet.

The cabernet, called Darmagi, is 100 percent cabernet and was first planted in 1978.

The vintage just released, 1988, has only 10 percent cabernet in the blend.

Since then, it has appeared in almost every vintage with about 20 percent cabernet.
