What's the ideal amount of coffee to use per cup of water in a French press?   I've looked at various online resources, which all gave me a different amount. Some call for 2 tablespoons per 6 oz of water, others per 4 oz. Others said to use one or the other, and add water after brewing if it's too strong.  So what's the ideal blend for extracting the best flavor? 
I don't know if there's an ideal ratio since this is really about how strong you want the coffee to be. It depends on the strength of the roast you're using, the grind, and how strong you like the coffee.  I generally use 2 tbs / 6 oz, but vary it to taste.
