Although it’s the oldest wine region in Portugal, Dão in central Portugal does not have the high profile of its neighbor to the north, the Douro Valley. And yet, Dão is the birthplace of the touriga nacional, one of the finest grapes in Portugal, a country with more than 300 different grape varieties. Considering this claim to fame, we thought the overlooked Dão region deserved a second glance. If we had any doubts about making the trek out to Dão, they were put to bed by André Ribeirinho. A Portuguese writer and wine judge, Ribeirinho knows the best small-scale Portuguese wine producers and champions them on his website Adegga, a platform he founded to review wines and host wine markets.
