Make simple syrup by cooking sugar and water on medium heat until dissolved. (I usually make at least a cup in case the sangria needs extra.) Let cool to room temp.
Mix all ingredients directly in serving container. Add simple syrup last and to taste. Amount will vary depending on the variety of wine and sweetness of juice. (The higher quality of juice the better the sangria will taste.)
Add fruit. Letting fruit soak for a couple of hours before serving is declious!
