The World of Ratios: Coffee to Water

If you haven’t noticed yet, your standard coffee pot at home has a bunch of irrelevant numbers on the side of the glass carafe, claiming they represent “cups” of coffee in which the vessel holds.  With a quick Google search, you will find a wide variety of equations to help you figure out which measuring system they decided to use to sell the brewer to you.   Most often, they are not actually 8 ounces, which is a standard cup in the U.S.A.  Normally it’s actually somewhere between 4-6oz and they claim its a European thing. I don’t know.. I do know that the metric system is amazingly simple, based on the weight and volume of pure distilled water, and can easily be used when formulating a brew ratio. So yet another reason to ditch the standard system of measurement used by us Americans. It just doesn’t make sense. With that said, I’ve attached a PDF of a brewing chart that might help guide you in brewing up some coffee.  I’ve also considered brew strengths and preferences, along with a few comments about how brewing weaker coffee is better for the restaurant’s bottom line, and brewing thicker coffee is better for the roaster’s financials. In the end, a well balanced and brewed cup is probably better for everyone financially, in the long run. But we have a hard time thinking long term, as far as quality goes.  Anyhow, give the chart a look and tell me what you think. Thanks!
