I rode the Bon Ton Roulet a couple of weeks ago. It was great, and quite hilly. I had my bike with a compact double, but my legs would have really appreciated my other bike with a triple. I also got rained on, but it was actually kind of fun. It was blissfully cool compared to the SE US at the same time. I am not able to do wine tastings and continue on a bike, so I didn't taste any wine on the trip.
Enjoy your ride!
