Any sign of channeling is telling you something about what’s going on inside the puck during extraction The surest way to spot it is by looking at the underside of your portafilter while your shot is pulling. Spraying, gaps in extraction, and the way the first drops come through the filter can all be warning signs.

Getting your grind correct is key to making the best crema. Ideally, you’ll want to have your grind fine enough that when tamped (remember 30 lbs. pressure), you’ll deliver roughly a 25-second shot.
Does finer grind make stronger coffee?
Simply put, the size of the grind determines how long the coffee will take to extract. A finer grind creates more surface area for the water to run through. It can create a stronger flavor, but this is mainly determined by the extraction time and, not the grind itself.
