Put tea bags in a heat proof pitcher. In a saucepan bring water just to a boil and pour over tea bags. Steep tea 5 minutes and remove tea bags. Cool tea and chill, covered, until cold, about 1 hour. Stir in syrup to taste and vinegar. Squeeze lime wedges into tea and add wedges. Serve tea over ice in tall glasses. Makes about 4 cups. To make simple syrup: In a saucepan bring 1-1/3 cups sugar and 1-1/4cups water to a boil, stirring, and boil until sugar is completly dissolved. Let syrup cool and chill, covered. (Syrup may be made 2 weeks ahead and chilled, covered.) Makes about 2 cups.
