I've seen that book. The author seems to have just decided to stick in their very own label for a roast level in between a couple of the standard roast levels and call it espresso roast. They could just as easily have called it dinosaur roast or purple roast. They're the only author I've seen who seems to think it exists.

I burr my grind my beans all at once. If I read your post correctly, you grind as you brew?

Yes, I grind as I brew. Coffee goes stale very quickly, and the greater the surface area the faster it goes stale. You get the best flavor by pulling your shot no more than 30 seconds after grinding.
