Thought the 'bloom' step for pour-over was just for show

My brother in Seattle kept telling me to pour a little hot water over the grounds and wait 30 seconds before the main pour. I figured it was a waste of time. After skipping it for a month, my coffee tasted a bit sour. Tried his method again last Tuesday and the flavor was noticeably smoother and sweeter. Anyone have a different trick for fixing a sour brew?

Oh wow, you just did a whole month-long science experiment to prove your brother right. Classic. That bloom step is like the coffee grounds stretching and yawning before they have to get to work. My trick for sour coffee is just grinding a tiny bit finer, seems to help.

Yeah the grind size thing is huge. @marymorgan I tried that once but went too far and choked my pour over, ended up with this bitter sludge. It's a tightrope walk. My brother uses a cheap blade grinder and wonders why his coffee tastes like pennies. I told him it's like trying to bake a cake with flour chunks the size of marbles.

Remember my old blade grinder... it made such a mess of sizes that every cup was a total surprise, like a weird coffee lottery. Honestly, switching to even a basic burr grinder felt like turning on the lights in a dark room. It's not just about avoiding sludge or pennies, it's about getting a taste that actually makes sense from one morning to the next. That consistency is what finally made the whole ritual feel worth it for me.
