On the Folgers website, it has a calculator. Place the number of 'cups' of coffee you desire and it tells you how much coffee to use and how much water to use. I put 8 cups, and it gives the following. 'For 8 servings of coffee use 8 tablespoons of ground coffee and 6 cups of water.' What?!?!?! is this 6 eight ounce cups for 8 six ounce cups of coffee?
Yes. Strangely, a standard "cup" of coffee (at least in the US) is 6 ounces (177ml). That's especially weird since most of us drink huge mugs. Go figure. So according to Folgers, to make 8 "servings" (48 ounces, 1.4 liters) you should use 8 tablespoons of coffee (42 grams) and 6 cups (48 ounces, 1.4 liters) of water. See also: Is a "cup" on a coffee maker always 6 oz? Is this a standard in the US?
One Tbs of ground coffee brewed in 6 oz of water is a common recipe for a single serving of coffee. The phrase "a cup of coffee" uses the word "cup" in a sense that does not mean "8 ounces" ... understandably confusing. In the end, you should adjust the ratio of coffee to water to suit your tastes and the particular roast.
I prefer to weigh the coffee. Most home coffeemakers are "10-cup". A good starting point is 1.25 to 1.5oz of ground coffee (use more if it's a coarse grind) per 10-cup pot.
For commercial 12-cup brewers, start at 1.5oz and work up... 1.75 or 2oz is generally ideal.
Starbucks uses almost 3oz to brew a pot, but they are doing all of the following: -Using a gourmet coffee -Using a very coarse grind -Brewing it wayyyyyyy too strong
Keep in mind for lower quality coffees (e.g. Folgers) with a lot of Robusta (vs Arabica) coffee in it, you'll need less coffee to get the same strength.
