Foundi Estate Xinomavro 2017, also referred as Ktima Foundi.

I think it is this winery.

This was an excellent wine and of course, having it at a rooftop restaurant in Hania (Chania or Xania) at sunset didn't hurt.

This was an acidic, complex, delicate and balanced wine. It did not feature oak or ripe grapes nor was it overdone in any way. Very deft winemaking. Has some overlap with Barolo, as many mention. I guess this is a very traditional winery. Highly recommended. Maybe 30+ Euros in the restaurant. Cellartracker notes are helpful on this.
