Most people skip the bloom. That's why most people's coffee isn't as good as it could be.
The bloom is simple: before you start your full brew, pour just enough hot water to saturate the grounds — about twice the weight of your coffee — and wait 30 seconds. That's it. But what happens in those 30 seconds matters.
Why it works. Fresh coffee contains CO2 trapped inside the bean from the roasting process. When you pour hot water over the grounds, that CO2 releases — you'll see it bubble and expand. If you don't bloom first and just pour all your water at once, that CO2 creates a barrier between the water and the coffee, resulting in uneven, under-extracted flavor.
The bloom tells you how fresh your coffee is. A vigorous, domed bloom means your coffee is fresh — roasted recently, full of CO2. A flat, barely-there bloom means your coffee is old. If your coffee doesn't bloom, it's stale. That's useful information.
When to bloom. Any pour-over, Aeropress, or French press benefits from a bloom. Drip machines can't bloom (another reason pour-over beats drip). Cold brew doesn't need it — cold water doesn't trigger CO2 release.
The technique. Pour slowly and evenly. Make sure all the grounds are saturated. Watch it rise. Wait the full 30 seconds. Then continue your brew.
Thirty seconds. Every time. Don't skip it.
