First of all I'm sorry you weren't satisfied with the tour.
The thing I regret is that in the last winery you only tasted 2 wines but they didn't tell me that the others were no longer available. Anyway this roadside winery is a very good working winery (they also gave you a bottle probably to say sorry to you they only have 2 wines available although that's a good sign for a winery don't have anymore wines available) and it's a winery that I think will become more popular in the future.
As for the "coop" it is the most famous in Italy and every year receives excellent scores from magazines also in the USA and is located in the center of the small town of Barbaresco (not just any village).
It is fine for my wineryr which is located 2 km outside the Barbaresco area but in any case you have tasted other varieties such as the Barbera of the area.
When the next day I asked you how the tour had gone you told me wonderful fantastic day then after sometimes you starte to complain about the restaurant and I did not argue and I immediately transferred the requested amount by paypal to you.
I'm happy the day after the tour guide was great and told you what you wanted to know regardign Barolo wine. I don't understand how my brother that makes wine himself and own a winery couldn't give you more information regarding Barolo then the guide the day after.
The comment on the timetable seems excessive to me because it becomes difficult to be precised. It really depends on how the day goes if there are delays or not and in your specific case if you remember initially you had to share the tour with 4 other people who had already booked but I tried to do everything to move them the next day to please everyone. In case there are multiple couples sharing the tour one can be brought to the hotel before the other and that also determines the arrival and departure times. You were alone.
I finish saying in all of your tours you got how many times you had the orwner of a winery guiding you, someone that make wine himself. I think unique experience compare to someone that might repeat the same story every single day that has been listen from some else before.
Learning from mistakes so thanks for your review.
