I kind of doubt they'll have it next year because of the success of Carsland.
When they did have it, it was kind of like Epcot's - just a lot smaller. They had culinary demos, tastings, and seminars. There were only a handful of tastings. You could easily "tour" the festival in a couple of hours. It was fun, but if you go expecting/comparing it with Epcot's, you'll be disappointed.
