We had a great tour guide and a very interesting tour of this historical medieval chateau of 300 hundred years. Walking through the galleries of cognac barrels and the aging process...from the spider webs, to protect the barrels from bugs, etc, and during the wars some sections of the chateau served as a holdout for prisoners we could read their writings on the walks.
The tasting was at a separate building. We could taste as much as we liked but it was very strong stuff for refined taste. The prices were exuberant.

I took the 1-hour, 12 euro tour (the tour length is the same for everyone, the price varies only according to the quality of cognacs tasted at the end in the tasting room). I received a very warm welcome from the lovely Cecile, who speaks perfect English and was a very professional and informative guide when showing us through the chateau and the various cognac storage facilities. It's easy to find the entrance, right by the little roundabout before the bridge, loads of parking and close to other cognac houses, the river and the old town of Charente. I really recommend this tour to locals and tourists alike and they run all year round.

We took a relatively brief tour - about two hours I think - and thoroughly enjoyed it. The building was fascinating and historically important and we enjoyed learning about it's history and part in the development of the cognac trade.
