Is the coffee with tiger spot a good cup of coffee?
The so-called tiger spot generally means that the oil of ESPRESSO has the same markings like tiger fur, which is definitely not the oil that a good ESPRESSO should have.
Tiger spot is generally caused by the coffee machine's water temperature is too high, the handle stays on the brewing head for too long, grinding too fine, uneven filling pressure and other factors, the solution is to first check the pressure of the boiler, too high pressure may cause the extraction temperature is too high, the standard is about 1BAR, the outlet temperature is between 92 and 90 degrees; the handle should stay on the brewing head as short as possible Calculate the extraction time, if the extraction time is too long and the tiger spot appears, then it may be a problem of grinding degree, the standard is between 22-28 seconds; the filling pressure should be uniform and smooth, if it is the extraction of double ESPRESSO, you can judge whether the packing pressure is uniform and smooth by comparing the volume of the left and right cups.
Of course, do not rule out other factors, coffee is a complex system, so please provide as much data as possible.
