some c hing said the powder should be used to brew within 3-5 minutes after grinding
once the bean becomes powder the surface area increased a lot and the speed of oxidation increase also it absorb the humidity around
for fresh bean they expand when water comes in contact with the powder
for ground bean this expansion is gone
that makes the big difference

GOOD LUCK!
