I worked for a wine importer in NYC during my college years. They bought a recently discovered wine cellar that had four or five stories going down into the bedrock of the island not too far from Columbus Circle. The temperature was constant year around. The company used it for a warehouse for their wine and liquors.
Apparently the original owners had also been smugglers because there was also a tunnel that went down to the Hudson river. Anyway at the very bottom story where you had to climb down a ladder several large bottles of port ??? were found all covered with dust from the centuries. I dont know if they ever sold them or opened them.
Old port, interesting; there was a lot of Portuguese maritime activity in the upper eastern seaboard after the disaster at the Battle of Alcacer Quibir; a Canadian folksinger (either the late Stan Rogers, or Garnet Rogers, his brother) if memory serves mentioned that the town where they grew up was founded in that time frame (1578 or sometime not long thereafter) by Portuguese shipwreck survivors. After Portugal lost the flower of its nobility at that battle, Spain subsumed both Portugal itself and its overseas possessions into the ruling dynasty's possessions. Portuguese ships and sailors who didn't care to live under Spanish rule stayed out of Spanish territory, and made like wild geese into other parts of the world. That wasn't always easy -- those Kings of Spain were, for a few generations, rulers of more of the world's surface than anyone in history.
