Thread dried fruits onto six 6-inch wooden skewers. Place skewers in a heavy self-sealing plastic bag, being careful not to pierce bag with skewers. Pour 1/2 cup of the port wine and the lemon juice over skewers. Seal bag; turn to coat. Lay bag flat in a shallow dish. Refrigerate overnight, turning bag occasionally.
To serve, remove fruit skewers from bag. Discard bag and liquid. Pour 1/4 cup port and 1/2 cup club soda in each of 6 tall, thin glasses. Add a fruit skewer to each. Add ice cubes to each. Serve immediately. Makes 6 cocktails.
