SEATTLE — Hong Kong and mainland China are developing a strong thirst for wine, and Washington and Oregon are hoping for a taste of those growing markets. So far, only a trickle of Northwest wines make it to Asian countries outside of Japan. But experts say as affluence grows in China's booming economy, so will the demand for the finer things in life. The recession hurt U.S. wine sales to most of the world last year, but not to Hong Kong, where the value of American wine imports jumped 138 percent to $40 million.
