My only take on this matter is that you have to practice and tweak your setup. There's no black and white in espresso making. You either do it right or you do it wrong. Coffee of other kind has room for error, and thus is open to error that still delivers a lush cup. I, too, was once in this gentleman's shoes. Many years ago, when I was young and still green behind the ears, I ventured to Europe and fell in love with the various coffees there. Then when I came back, I went onto a path of buying what I could reasonably afford and amassed a small collection. There is so much fine tuning between types of coffees in terms of roast and origin, even the same single origin beans between vendors can be incredibly different. Now, granted I presume this gentleman is well versed on coffee given his past posts, what I can say and repeat at that, is that espresso is very unforgiving. Too strong a pull, and you don't get that white-ish crema, you get something dark and disgusting. Which is fine to serve as an Americano or add copious amounts of steamed milk and sugar, to make a sweet dessert coffee. Too weak a shot, and you get a crema that subsides quickly. It's a fine art. The concern of stale beans is an important notion. Beans freshly roasted will not be good for an immediate brew, given some time to breathe, they're fantastic. Beans stale for even 1-3 days will deliver sub-par results, no matter what you do.
And for what it's worth, I stayed out of this conversation because all the points were addressed and these other fine people have more patience and more knowledge than I do, despite having pulled shots for 3x as longer than they have. It's a continuous learning experience. One should always strive to better their coffee or tea knowledge. Having said all this, a lot of us, including myself, frequent other coffee boards or threads on other sites. So imagine my surprise when I come across a thread regarding this very thread today on another site due to a keyword alert. What little patience I had is now gone.

Had some hot-ish tea at work today thinking it was cooler (Damn deceptive stoneware mug!) and I didn't experience sharp pain. Soreness, yes. I'd like some guidance, though. I'm looking for roasters that do cinnamon roasts or one step above, preferably west coast to lessen shipping times. Does anyone have a recommendation? I think I'll break my coffee "fast" with a very light floral roast.
