Logarithmic deterioration of ground coffree (Score 1)

Well, fresh ground coffee beans is like a red wine bottle opened : It last 2 days. It's deterioration is logarithmic. Within the very first 48 hours, it loses about 25% of freshness. In the next 48 hours, it will loose maybe another 10% (don't apply to the vacuum sealed package). This is especially true if it is a very sharp coffee blend. Also true if you are perfect with your methodology of making a coffee. All the process from grinding until drinking must be very perfect to obtain the best from the grain and from the infusion technique.

So fresh ground beans are important if you master your technique. Otherwise either freshness or technique are not so important, it will ordinary coffee only.
Will alter the coffee freshness :
-light
-air
-moisture
-hot or cold
-your finger natural body oil
-time

To have a full caffeine coffee, use a Bodum and infuse it for 10 minutes.
I prefer the espresso, it's less caffeine, and the texture is not like water.
That taste is maybe because of my French background.
