What is the golden rule for coffee brewing?
The golden coffee ratio according to the specialty coffee association’s (sca) gold cup standard, coffee’s golden ratio is 1:18—1 gram of coffee to every 18 grams of water. This standard was originally developed for batch brewing, recommending 55 grams of coffee per liter of water to achieve a well-balanced extraction. With a 1:17 ratio, for every 1 gram of coffee, use 17 grams of water. This gives the best chance for an ideal extraction—the process of dissolving soluble flavors from coffee grounds using water—with a complementary strength. This ratio is optimal for manual and automatic pour-over methods.
What is the common problem of a coffee machine?
Whether it’s a drip coffee machine or a single-serve coffee machine, slow or no water flow is the most common problem with all home coffee machines, and there are a few causes behind this problem. Firstly, the water tank might be out of place. If your coffee machine is powering on but not brewing, the culprit might be a blocked water line or heating element. Mineral buildup from hard water can clog these components, preventing the water from reaching the right temperature or flowing into the brew basket[^2^].There could be several reasons this is happening. Possible causes for no coffee coming out of your machines include; no water in the reservoir, your coffee grind is too fine, there’s too much coffee in the filter, your machines isn’t plugged in properly or the coffee has been compressed too much.Possible causes for no coffee coming out of your machines include; no water in the reservoir, your coffee grind is too fine, there’s too much coffee in the filter, your machines isn’t plugged in properly or the coffee has been compressed too much.
