Hello, I am starting a coffee shop but I need to know how to calculate the amount of coffee I need. How much coffee goes into one twelve ounce cup? I imagine it would be in the tbl spn region, similar to instant coffee but I could be wrong. I'm am going to use 12oz 16oz or 22oz. So it would be practical to find out how much coffee per ounce. I am sUre there is an easier way. Nevertheless, if anYone can help I would appreciate it.

A normal starting guideline is one tablespoon per 'cup' of coffee...where a cup is 6oz.
So 2tbsp for a 12 oz volume.
Are you much of a coffee drinker? I have to ask because it seems like you are not...as you're assuming instant coffee and brewed coffee use the same volume of grounds. Are you really ready to start a business based on coffee?
People expect and demand good coffee from a coffee shop.

Are you planning on brewing each cup individually, as in a pour-over or press pot? If you're going to brew by the pot it would be easier to calculate for that, then divide by the number of cups or ounces per pot. To get you started, a very generalized formula would be: 0.2 pounds of coffee per 12 cup pot (those are six ounce cups btw)
Of course the amount of coffee you use per pot will depend on your brew volume, 12 cups to 1.5 gallons or more. Also it will depend on the coffee itself and your taste. I suggest you get your equipment set up and play with it until you get the proportions you like figured out and do the math from there.
Cheers.

Here are some of the calculations I've found scattered around the boards here:
Espresso = 1 - 1.5 oz for a single (7-9 grams per shot); 2 - 2.5 oz for a double (14-16 grams per shot) fine grind coffee Auto drip = 6 oz (2 tablespoons per cup arabica; 1 tablespoon per cup robusta) drip grind coffee Percolator = 6 oz (1 tablespoon per cup) medium grind coffee Press pot = 4 oz (7 - 9 grams per cup) coarse grind coffee Melitta 1-cup pour over = 6 oz (2 teaspoons per cup fine or extra fine grind on their web site) [I use 3 tablespoons medium-coarse grind or 2 tablespoons drip grind for a 10 - 11 oz cup]
Commercial grind measures (based on medium grind): 1 pound coffee = 16 oz = 60 heaping tablespoons = 75 level tablespoons = 5.25 cups approximately 1/3 cup or 5 tablespoons = 1 oz by weight
Instant coffee = 8 oz (1 - 2 teaspoons depending on variety, read label); note that a lot of instant coffees use robusta in their blend to give it a stronger taste
Other hints: - For auto drip and percolators it is best to fill the container with water and pour it off into a measuring cup to determine the number of ounces for the various cup marks -- i.e. is a 10 cup pot really 60 oz at that mark, or an 8 cup at 48 oz, etc. - Press pots are fairly standardized at 4 oz cups, i.e. an 8 cup press is 32 oz - Too much coffee used usually results in a bitter tasting brew - The type of roast (medium, dark, french, etc.) affects the amount of coffee used - Brewing temperature matters (generally around 200 - 205 degrees F or just before the water boils, auto drips run 160 - 190 degrees F) [generally 212 degrees F is considered the boiling point of water; this is affected by altitude and type of water used] - Tastebuds will tell you a lot about measurements - The taste of the coffee is dependent on the type of coffee used: commercial vs. home-roasted, pre-ground vs. whole bean; amount of time since roasting, etc. - Notebooks are priceless -- and these forums :-)
