Wine Advocate-Parker :
The 2017 Vintage Port Quinta da Ervamoira (in Douro Superior) is another Port from Ramos Pinto in this vintage that is Touriga Nacional-dominated--60% of the blend. The rest is Touriga Franca (15%), Sousão (10%), Tinta Barroca (10%) and Tinto Cão (5%). It comes in with 98 grams of sugar. This is another of those Single Quinta Ports that is not really intended as a downgrade over the regular Vintage Port. Rather, it is just a different expression of terroir--and it is actually pricier than the regular Vintage Port that Ramos Pinto also made in 2017.
