Easy process: (more waste) Pour the wine and spices in a large container. Wait 3 to 5 hours. Filter with a piece of old teeshirt. Filter again if desired with coffee filter. Add sugar and adjust to taste. Pour back in bottles or drink. Will keep at room temprature for about 2 weeks.
Long process: (recommended) Pour wine into large container. Put spices in a finely woven tight towel and tie shut making sure the wine will flow thru the spices and be permeated. Let the spice bag sit in the wine for 2 to 3 days, stirring occasionaly. Filter as above and add sugar. This method results in more yield because the spices wont turn into a slime blob at the bottom and use so much liquid.
