To make a stronger cup of pour over coffee, start by selecting high-quality, freshly roasted beans from reputable local roasters or online shops. Check the roast date to ensure freshness. Then, use a high-quality burr grinder to grind the beans to a medium-fine consistency. This will increase the surface area of the beans and allow for more extraction of flavors. Expert tip: Experiment with the grind size to find the perfect balance for your taste preference.
