A great place to taste a wide range of Portuguese wines from red to white to port. The person staffing the main desk was very knowledgeable and helpful when we stopped in on a bright, sunny, late December afternoon.
If you want a "guided tour" tasting, you have to book that in advance. Otherwise, you purchase a card at the main desk that allows you to sample wines of your choice -- they're arranged around the spacious, pleasant tasting room -- and as you use up the euros on the card, you can always top it up to allow you to taste more wines. The tasting is self-service: you choose a bottle you like, insert your card, press a button, and a pour of the wine then happens.
If you like a particular wine, you can go to the main desk and purchase a bottle of it. We found the vinho verde, the red from the red wine from the Douro region, and the two ports we tasted better than any of those wines we've ever purchased in the US.
Altogether a very pleasant experience tasting a variety of good Portuguese wines in the spacious, quiet tasting room, with good guidance from the staff person at the main desk.
