Best Coffee Maker of 2024
Evaluating the performance of your coffee machine is trickier than it sounds. What you need to know about what makes good drip coffee, and based on Specialty Coffee Associationthere are necessary standards for brewing good wine. Brewing time and water temperature top the list. The hot water should be in contact with the ground for not less than four minutes and not more than eight minutes. The ideal water temperature range is between 197 degrees Fahrenheit (92 degrees Celsius) and 205 degrees Fahrenheit (96 degrees Celsius).
To understand how each coffee maker handled this challenge, we recorded the length of their brew cycles. We also employ thermocouple thermal sensors connected to industrial grade data loggers. This allows us to record the temperature within the coffee grounds during the brewing process.
We measure the temperature inside the brewing chamber of every coffee machine we test.
After brewing the coffee, we use a meter to take a sample reading of the coffee liquid produced. Optical refractometer. This data allows us to calculate the total dissolved solids percentage for each brew, given that we take into account the amount of water and freshly ground coffee used. From there we get the extraction percentage. The ideal range is generally considered to be between 18% and 20%.
We also back up the measured data with good old-fashioned taste testing. Over-extracted coffee tastes bitter and sharp, while under-extracted coffee usually tastes bland or sour. To be sure, we ran the same test at least three times to get an idea of ​​the average results.
