Pietro great tour guide! Totally recommended trip to the douro valley! The drive there is really great too! Wine tasting and lunch were delicious, as was the Rabelo ride a great experience! Definitely worth it! (The first wine tasting with lunch was much better, as it was a smaller winery and a lot was explained about the differences from port wine (you could also taste the differently aged port wines), the second was quite large but also interesting. But less focus on the wine itself but rather on the system)
