There are lots of vineyards in this part of the Eastern Townships but this one is truly unique. You have the impression of being in Europe because all the buildings have been built of stone in a very traditional way, the cellars have been carved out of sheer rock and the chapel looks like it could be hundreds of years old. The tour takes about 90 minutes ($15) if you include the tasting (optional for an extra $10) and includes a look at all the buildings as well as the beautiful site and the cellars and vineyard itself. Note that you cannot just turn up - if you are a group of 6 you can pre-book otherwise you have to join an open tour run on Sundays and Wednesdays at 1.30pm. On the day we went there were a lot of people and the tour was run in both English and French which was a little tedious at times but still worth it. Their speciality is a sweet wine worth bearing in mind as regards the tasting.
