Walla Walla may be a name that runs trippingly off the tongue, but the wines of this relatively new region are not yet the first Pacific Northwest bottlings that come immediately to mind. Spread across the southeast corner of Washington state between the Columbia and Snake rivers and dipping down into Oregon, the area only began to make wine in the 1970s. Until then, it produced apples and wheat. Today, those orchards have become vineyards and farms are now wineries, about 130 of them at last count. And until I tasted the wines of Pepper Bridge and Amavi, I did not appreciate how fine the wines of Walla Walla could be.
