Wine Touring in Greece

My brother and sister in laws are honey honeymooning in Greece next month. They will be in Athens, Mykonos, and Santorini. Can anyone recommend a good winery or two to visit?

On Santorini, I would strongly recommend visiting Sigalas

Take your question to this blog. Marcus will know what to tell you: http://www.elloinos.com/

Sigalas, Argyros, for sure, and then Boutari and Gaia.

The first 2 for sure on Santorini.

Also Hatzidakis who is in my view the most interesting producer of Santorini:

My wife and I enjoyed a tour offered by Wine in Santorni:

We also visited Domaine Sigalas separately from the tour, and it was a fantastic experience. They have a beautiful patio area and some nice food, in addition to letting you taste a ton of wines.
