- 4 quarts of coffee seems like a lot in terms total volume (i.e. you might be diluting the beer to much), but you say nothing of how strong the coffee will be. how many ounces of beans/grounds are you adding? check out http://www.homebrewtalk.com/f68/foun...-clone-139078/
for some ideas - for that recipe, it's 2 oz at the end of boil and 2 oz cold-steeped at bottling.

- seems high on the crystal, i'd cut it in half
