Very interesting visit on the manufacture of Porto. However, the visit lacks a little organization with the audioguide, in fact, it is repeated often and we are lost in the visit after a while ..
However, the wines tasted at the end of the visit are excellent, I recommend you take a cheese platter with (they are delicious too) and they can sublimate the Port.
The price of the visit is 15 euros with 2 glasses included. The amount of wine in the glasses is quite reasonable.
