To answer your question, just an expat doing the English lang teacher thing....Kinda fell in love with the country, my job here, the food, the climate, one of the locals....
Check out my other post about beefing up the Lexicon, which I found lacking in Portuguese wine references.
Again, should anyone need help, references, etc....I'm here.
Also, I can HIGHLY recommend a visit to the Douro River Valley (UNESCO World Heritage, for its wine-producing past). GORGEOUS landscapes !
