Washington State is the second largest wine region in the U.S. behind California. Which of the following is NOT one of top 4 wine grapes grown in the State?

D.

More than 40 grape varieties are grown in Washington, but three quarters of the wine production is made up of just four grape varieties: cabernet sauvingon, riesling, chardonnay, and merlot. Syrah comes in fifth with only a half as much produced as fourth-placed merlot. That said, syrah is the grape to watch here. The quality of Washington State syrahs is shockingly good.
