You need 17 grams of coffee beans and a light roast coffee of your choice first. Make sure to use a portafilter or a hybrid portafilter which will help reduce mess. Start with a puck paper which goes at the bottom, add a little water, and use a paper towel to dry the sides. Spray a very little amount of RDT on the coffee beans which will reduce electricity and apply WDT on the beans to equal the amounts of coffee grounds used. Put the puck screen on the top then warm it up before shooting. You should focus on achieving a yield of 50 grams of coffee out in just under 20 seconds. This method produces an espresso that is light, bright, sweet, and has a nice balanced flavor.
