Yakima, WA - Friday marks the beginning of the pre-barrel wine tasting. Next weekend wineries start barrel tasting, which is more of a festival with bands and bbq along the wine trails. This weekend is a smaller gathering, for more serious wine drinkers...and inexperienced ones that want to learn. Organizers say pre-barrel is becoming popular in recent years, as more and more people thirst for knowledge about wine. There are over four hundred wineries in washington ... Up from just eighteen twenty years ago, so that leaves plenty of wine trails to explore. The Rattlesnake Hills Wine Trail in Zillah has become one of the more popular local trails.
