Do coffee distributors actually help, or should you skip them? This is video 3 in my puck prep test series, where I use a refractometer to find the most efficient espresso routine.

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.

What should I test next? #espresso #homebarista #puckscreen #coffeetools #coffee
