I thought the 'bloom' step for pour-over was just for show

For a year I just poured all the water at once, figuring the 30 second wait was a waste. A friend in Portland made me try it his way with a scale and timer. My usual 20 grams of beans actually bubbled up and expanded a full inch in the V60. The next cup tasted way less bitter, like a different coffee. Has anyone else skipped this step and been surprised by the change?

Honestly, I was the same way for a long time. I figured it was just coffee theater, something for the fancy cafes to do. Then I had a similar moment with a scale and saw all that gas escape. It clicked that it's not just waiting, it's letting the coffee get ready for the main pour. The difference in the cup was impossible to ignore, way more balanced and sweet. I won't skip it now.

That big bloom shows the beans are off-gassing a lot of carbon dioxide. If you pour right on top of that, it can block the water from getting to the grounds evenly. So is the real benefit just about avoiding channeling, not some special flavor magic?

It still seems like a lot of fuss for a hot drink. My old drip machine never did a bloom and the coffee was fine. All that gas and bubbling might just mean fresher beans, not that the step itself is magic. I tried it a few times and the taste change was so small it could have been in my head. People get really into the ritual of it, which is fine, but calling it a game changer feels like overkill.
