What are your favorite wineries between Salem/Portland? I live in Eugene but, shamefully, haven't spent much time in Oregon wine country...but a visit from my midwestern mother is prompting me to (finally!) plan a day trip. We'll be carving out probably about six hours for the winery tours and aren't so much interested in viewing their operations as we are in knocking back some outstanding pinots. :)
I'd love any and all suggestions along with advice re: whether reservations are suggested/required for a Friday visit. Thanks!
