Professional coffee tasters use: exactly two (2) tablespoons (7 to 9 grams or 2 scoop of a standard coffee measure) of ground coffee beans for each six (6) ounces of water. For 4 cups (6 ounces each) of coffee, measure out 8 generous tablespoons (30 to 35 grams) of fresh ground coffee beans.
The recommended amount of coffee in the article, by weight, is approximately 30 grams (1 ounce) per 12-16 oz of water. So, in the example from the original question, for four cups (at 6 oz per cup) you would want 60 grams (2 ounces) of coffee.
