I serve the beverage in a mug, because it allows me to add extra milk if the recipient wants a "weaker" coffee. Both of my daughters (adults now) enjoy coffee. I rarely add 200ml of milk for my self, but enjoy drinking from the mug as it is a very ergonomic shape. Depending on the blend and the age of the beans, I also like an intense extraction, especially if I am drinking espresso. However, too intense an extraction tends to emphasize the choc and cocoa notes too much, and I prefer a balanced espresso. A 50-60ml extraction yields a very nice base for a milk drink as described. If the bean is a single origin, then I tend to pull shorter extractions, about 30-35ml. To get very intense and thick extractions, I intend to experiment (when I have some time) with lowering the pstat to about 1 bar (currently on 1.2 bar), and seeing if I can copy the result that Bar9 used to achieve with their Lever: http://www.jimseven.com/2009/06/02/using-a-lever-machine/ "I totally agree with the notion of abandoning all pre-conceived thoughts or “rules” for espresso when dealing with a lever piston machine. When we first got our Z9 lever I really wasn’t expecting much in terms of pulling a decent shot (direct boiler, no saturation at the group head etc), it was more about the aesthetics than anything else. However after playing around a bit it now pulls the most amazing shot! The pressure-stat (mercury switch) is set really low so the thing is useless for milk, but after letting it heat up for around an hour it’s all good to go. At the moment we’re running it single spout with synesso triple (24g) baskets. 8-10second pre-infusion and cutting the shot normally (usually take around 35seconds incl pre-infusion). The result is the thickest “espresso” you’ve ever seen. You literally chew your way through it the whole way. Now normally I’m not big on massive body, and far more excited by clean and interesting flavours, but this thing is incredible! The flavour profile is not (like you would expect) ristretto-esque either, though definitely not like a standard espresso either. I should also mention that the temps @ the head are wild too, beginning at 97C and dropping to 88C by the end of the shot. It still boggles me every time I pull a shot through it but damn it tastes good." When they first opened in Adelaide, I went out of my way for the espresso from their Z9.
