[An abbreviation of Oporto, a town in Portugal, whence it is shipped; Port.oporto =the port.] [PORT (1), 8.] Comm.: A species of red wine, produced chiefly in the mountainous districts of Portugal, and shipped from Oporto. After the juice has been pre ed from the grape, and fermentation fairly started, a certain quantity of spirit is added to impede the proce , so as to retain in the liquid scme of the saccharine matter, as well as the flavor of the grape. A good port-wine should po e body and aroma, a full and rich color, moderate fruitine , and be neither too sweet nor too rough. The proportion of proof-spirit varies from 26 to 36 per cent. It is frequently adulterated, both before it reaches this country and after its arrival here, sometimes by the addition of inferior wines or elderberry juice, at other times by diluting with water, adding a cheap spirit, and restoring the color by means of logwood or some other dye. A little powdered catechu is also occasionally added to produce a rough and astringent flavor and to insure a fine crust.
