The side of the bags that come from Klatch say "Measure 2 tablespoons of ground coffee per 6 ounces of water".
Stumptown's various brew guides on their website imply that one tablespoon of coffee is approx 7grams.
I've been alternating between the above two methods (and a few others) to experiment recently. The first (non-dilute) gives a sharper taste profile. For lack of a better descriptor it made the coffee more sour (I used a light roast). The stumptown method still brings out the flavor but does taste a bit more mild. My preference oscillates based on time of day and other miscellaneous factors that have nothing to do with the coffee.
