My friend told me my pour-over technique was way too fast, said it tasted 'sour and weak'. Slowed it down to a 4-minute brew and wow. | Coffee Enthusiasts - nhfree.com
Huh, I never thought about it that way. But honestly, I've had the opposite problem where grinding too fine made my coffee taste like mud, especially with lighter roasts. Maybe it's just me, but I've found that adjusting my water temperature down a bit helped more than messing with the grind size. Like, if your water's too hot, it can scorch the grounds and give you that bitter edge even with a coarser grind.
