I know of someone at coffeegeek who allows his roasted espresso beans to rest around 11 days prior to making espresso.

And the best commercially made espresso coffee I ever drank was during the 80's at Caravanserai in Berkeley - made by a Greek. Otherwise 'twas chez moi using a Sama Lever machine and beans less than 7 days post roast. Tastey.
