Welcome to the series where I test puck prep tools with a refractometer. Today was all about puck screens. Thin screens ( 0.2 mm ) gave a small bump. But thicker ( 0.8 mm )screens gave a big jump in extraction. Same ratio, same prep, real numbers. Honestly impressive for such a simple tool. What should I test next? #espresso #homebarista #puckscreen #coffeetools #coffee
