What can improve your quest for the perfect espresso taste? Proper coffee distribution in the portafilter. Tapping the edge of the coffee machine lever is a relic, don't do that anymore. Rather use the proper tools like the dosing funnel, coffee distributor and WDT coffee tool. Dig through the ground coffee in the portafilter basket with the WDT espresso tool and squeeze with a good quality frother or straight up automatic tamper. You will notice the improved taste experience immediately. And did you know that the WDT tool also helps with pour-over methods of filter coffee preparation?
