According to the Specialty Coffee Association of America (SCAA) there is an ideal method for making coffee, called the Golden Cup Award, which will scientifically yield favorable and repeatable results. You should use between 3.25 and 4.25 ounces of coffee grounds per 64 ounces of water (90-120 grams of coffee to 1.9 liters of water). The water temperature must be at 200 degrees Fahrenheit (+ or - 2; that's equivalent to 93 Celcius) when it comes in contact with the grounds. Lastly, the total dissolved solids (TDS) measured in any given brew tastes best to most people when it falls between 1.15 and 1.35 percent.
Good news to all those coffee lovers out there: That cup of joe has quite a few health benefits, as long as you don't load it up with cream and sugar. A number of health organizations agree: The World Health Organization in June 2016 took coffee off the list of potentially carcinogenic foods, stating that java possibly protects again certain cancers, while the 2015 Dietary Guidelines Advisory Committee declared that three to five cups of coffee a day can be part of a healthy dietary pattern. In fact, research shows that black coffee can have a positive effect on conditions including diabetes, dementia and depression.
