Yes, there are best three ways for coffee enthusiasts who need help with tamping, here we go;
Door-knob handles method – this is a commonly taught method at cafes as it sounds. However; what you have to do is, hold your tamp like you’re holding a doorknob, and with your body parallel to the table at which you’re tamping, you’re going to press down on that espresso with your elbow at 90 degrees. It’s quite easy!
Three-finger tamp method – the second method is something I usually prefer the most. Here, you have to hold the tap with three fingers on the edge of the tapping surface, so you can feel the brim of the portal filter evenly when you press down once, you place the tampon on the espresso, keep pressing until three fingers reach the brim of the portafilter, and you should even get an even tap.
This looks symmetrical! You’ll see variations of this everywhere because it’s one of the best ways.
Thumb press method - This technique is slightly different from the others as you can directly face the tamper head-on, and I’ve seen this one used by many expert baristas as a coffee fest and by other competition. In this method, you’re using thumb and either one finger or two fin gear on the opposite end of the tap to get an even press
Now, it’s the most economically friendly tapping method, yet is superb in getting the best attempt! Whatever tamp you choose from coffee tamper suppliers, the best you use, the best espresso you’ll make, so it's all up to you.
