I'm glad you asked Dan. Luca is pretty right on with what he said. Espresso is a layered drink when you think about it, and "flipping" the shot is something that we at PT's came up with especially for tasting at the barista competition this year. If you haven't done it before try pulling a shot between 3 separate shot glasses filling 10ml in each until the extraction is done. If you taste them, you should find the first 10ml to be very sweet and heavy, second hits more acid and body, and third is quite thin in comparison with more of the floral and bitter notes. Now think about how the shot pours and you see that the thin, less preferable flavors are in the first sip. I have to thank our roaster Marty Gish for the initial idea for flipping the shot. Back to your actual question, we did have issues with losing crema points when practicing this method. What it came down to in my mind is speed of service. You don't want your shots to sit anyway, but just stepping up my haste helped preserve the color and persistence of crema. In fact, one of my judges in the finals wrote "great crema!" on my score sheet. So in my opinion, the gain on the flavor side completely outweighed a very small loss if any on the crema components. I would encourage everyone to try the "PT's flip" as we have been calling it. Pull a double shot, one straight into a demi and the other into a preheated shot glass and pour it into a second demi and try them side by side. Doing a blind tasting is even better. You might just be amazed that both shots, especially on that first sip, came from the same portafilter. On a final note, I don't feel that this is a step that should always be done especially at a cafe. As I said before, espresso is a layered drink and I find that part of the enjoyment is tasting the changing flavors as you drink it down.
