When you need to have the right amount of coffee in your portafilter, Say for example 20 grams. Then you can do it circuitous. And take a lot of time. Or you can do it the fast way. Let me demonstrate the circuitous way first. Have a look. First taring the portafilter. Can you see it? 0 gram. Fill the portafilter with coffee. Like this. That’s not enough. Add some extra coffee. Yeah, that’s too much. Let take some coffee away. Yeah, that’s still too much. Like this. Ah, just too little. This is not going to work. It’s takes way too much time. The coffee gets old. Let me show you how I do it. And take advantage from it. Have a look. Now I am dosing a certain amount in my portafilter. That’s clearly not enough. Now I am taking a cup. and a spoon. I fill the cup with coffee. And add the coffee from the cup. It’s exactly 20 grams. Voilà. Thanks for the tip! You’re welcome.
