We spent the afternoon walking around the "Funk Zone" in Santa Barbara - adjacent to railroad tracks, just east of State Street and found many wineries/tasting rooms for excellent wineries within a 3 block area. If you are tight on time and want to taste some great local wines without driving all over the county (and risking an accident), it is well worth spending part of an afternoon walking between locations for tastings and snacks. Some also feature live music and food trucks if they don't serve any snacks. Most close by 7pm so it is definitely a daytime activity.
