    What are these bubbles?

    I think it's the CO2 that comes from fresh coffee.

    i'm going for high acidity too combined with the fact that it took you a little while between pouring the milk and getting your camera out so the coffee had time to go "off".

    what milk are you using? high acidity + most soy milks = tofu blooms. this isn't a tofu bloom and i doubt you're using soy, but that's another fairly common source of mottling and bubbling on the crema of a milk drink.

    Yes I did run and get the camera. I suspect it's fresh beans? Roasted 20/08. It's Byron Bay coffee. I'll try again tonight.

    It probably is from letting it settle a bit before taking the photo. I also find you can eliminate that by breaking the crema up slightly with the way you introduce your milk, or just swirl the espresso in the cup for a couple of seconds to loosen everything up (it turns creamy gold) then pour the milk.
