Kevin Robinson traveled more than 500 miles from Orange County this week to taste Sonoma County wines, but his friends from Nashville did him one better. For their sixth consecutive year, the friends flew 2,000 miles to participate in the second and final weekend of this year’s Wine Road Barrel Tasting. The group of eight was among the thousands of wine aficionados who descended upon tasting rooms in the Dry Creek, Russian River and Alexander valleys over the weekend to sample future vintages of more than 100 wineries. For many, the event, now in its 32nd year, has become a tradition.
