I would give this 6 on a 1 to 5 scale. We just got back from our Brewery & Spirits tour, and oh man it was awesome. We visited some really good breweries, a farm, a distillery and finished with a cidery. Those were all great, but Natalia's knowledge was the star of the day. She knows so much about what to and what not to do around the state. We had originally planned on doing this tour on Tuesday, but being a celiac, I was really looking forward to Woodchuck cidery. We switched to Thursday instead, and Natalia was was accommodating about that. I would highly recommend doing this early in your stay, so you can soak in Natalia's knowledge to help guide you on the rest of your trip. The itinerary was planned out perfectly with a stop at the Dakin farm in the middle for a quick snack (via awesome samples), then a later lunch at Otter Creek.
I cannot recommend Natalia's services enough. A MUST for your visit to Vermont.
