very true but all in all not a bad habit to incorporate into your regular coffee routine anyway, just for good measure... what I do find helps with my four group machine, however, is to run the steam wand straight to the side of the milk jug, and to begin with building a 'whirlpool' motion with the milk straight away, rather than the traditional 'stretch and roll' motion - thus using the pressure of the machine to your advantage, and dropping the jug down gradually, as the volume increases, then gradually reducing pressure just before the milk comes to the boil, so that you are not caught out by the sudden boiling point of the milk also, I find that milk jugs with a rounded base tend to gather and distribute the milk a lot more evenly, as do those with a more solid construction, which allow for a more even heat distribution... now there is food for thought! p
