We arrived excitedly today in the beautiful Douro Valley and our first stop was Carvalho Vineyarrd. And That was our first big mistake. Our second was to pay 19 Euros for a for glass sampler from an extraordinarily rude and arrogant attendee (presumably the company front person) behind the reception desk. Sadly, she was as sour as the wines that we subsequently drank. It pains me to describe how terrible each of these wine was (with the exception of the 10 y.o. Port). We shared three reds and a white progressing up a supposed ladder of quality. Each was frankly as undrinkable as the next, unvarigated, but for a bitter aftertaste one might equate with a rough acidity or some cleaning agent. These were, without doubt, the worst wines we have tasted in Portugal. To be avoided at all cost,, as was the woman at front-of-house!
