I 'know' that freshly ground coffee is the best there is (within the quality of the beans, that is).
The question is whether this is true. Freshly ground coffee smells great, but does that affect the flavor after brewing? How long do these volatile flavors or smells last before the coffee goes 'stale'.
Can anybody (experts) taste the difference between freshly ground and brewed or not so freshly ground coffee? If so, what differences can be observed?
Edit as per talon8's link:
- Freshly ground: brighter acidity, richest flavor.
- 9 hours: very similar to the freshly-ground coffee, although a bit mellower; less “bright” notes.
- 24 hours: some of the fruity flavors have faded; a bit less flavor in general.
- 7 days: duller, significantly less flavor overall.
To the people that notice the difference in taste, do you agree with these observations?
