NAPA VALLEY, Calif. - Basking in the California sun, are plump and picturesque wine grapes, but, most of all, these vines are growing profits. At Leonesse Cellars in Temecula, business is far from sour. These businesses had to adjust their wine bottle price range. Some bottles range anyway from the late teens all the way up to $90 or $100. It is one strategy that is making the U.S. wine industry robust in a really dry economy.
