Taste the Season NOTL experience?
I'd say that it's worth it if you are going to be spending more than one day touring and tasting. I personally find that more than 4 or 5 wine tastings in a single day burns out my taste buds and interest. But if you were to do, say 3 or 4 a day over the course of a few weekends in the month, than it's definitely worth it.
The food tastings range from ok to quite good. As for the wines, NOTL offers the full range from blech to delicious, so it helps to pick carefully. :o)
The nice thing about the event is that it's just the NOTL wineries, which means that even the most far flung location is never more than 15 minutes away from the next winery.
