Some people do PTB's method, but with a dash of cold water, to cool the hot (usually boiler) water, so as not to burn the espresso as it enters the water. Me ... I drink milky drinks and espresso. If I'm after a longer black coffee, I drink plunger, but then, I'm not a barista workin in a cafe! But if I was to order a LB, I definately wouldn't drink it if it was a 120-200ml extraction ... if you're not sure why, pull a 120ml shot from a double basket .... and taste ... if you're game.
