Tried blooming my coffee grounds with half the water first

I read about this method for pour-overs and gave it a shot with my $30 Chemex clone. The flavor was way smoother, no bitterness at all. Anyone else mess with their bloom technique and get weird results?

47 degrees Celsius is actually the sweet spot I found for blooming, not the usual 85-95 people recommend. I use a meat thermometer to check it. Tried it after reading some old coffee science papers from the 1950s and the lower temp lets the gases release slower without pulling out the harsh acids. You end up with this almost tea-like clarity in the cup that really lets the origin notes shine through. Might sound crazy but it fixed that bitterness issue for me completely.

Oh man, I feel you on this one. My first time trying the bloom technique I actually messed it up pretty bad and ended up with a weak, watery cup that tasted like nothing. But once I got the timing down and stopped rushing it, it made a huge difference in my daily brew. That smoother, less bitter result you got is exactly what I found too, it just takes some patience to nail it. I think a lot of folks give up after one bad try but it's worth sticking with.

Start with a meat thermometer, huh? I've been playing with cooler bloom temps since I saw that same old research referenced in a coffee forum ages ago, and let me tell you it really does unlock something different. @lewis.terry, you mentioned that smoother cup after nailing the timing, and I think pairing that patient approach with a 50 degree bloom instead of the standard hot water just amplifies the effect. I usually pour just enough to cover the grounds, let it sit a full 45 seconds to a minute, and the flavor clarity is night and day compared to rushing through a hot bloom.
