title_body: What grind setting should I use for french press using a Capresso Infinity conical burr grinder?
upvoted_answer: I would recommend looking for which coarse setting seems to produce the most even grind. Really, the only potential danger you have is grinding so fine that you can't push the screen down.
  
  The reason I recommend this is, like you mentioned, because everything else can be altered to your coffee's grind - the water temperature and extraction time. So you'll want to dial in a grind that's going to be evenly extracted. If your most coarse setting gives you big chunks and a lot of fine particles as well, then you're either going to over extract the fine and under extract the coarse, or vice versa depending on your brew time.
  
  I hesitate to give you a dogmatic answer because I don't want to mislead you, but I also understand that it takes time to recognize even grinding and the grind size that is appropriate for the brew method. So I'll say that somewhere around medium to medium-coarse is going to be better. With smaller burr grinders, the coarsest setting has pretty uneven results.
  
  Also, try playing with the extraction time. Start with two minutes, then try 3, on up to 5. If you keep everything consistent, you should be able to find exactly what works/tastes best for your situation.
