I didn't know whether to post this in food & drink or here!
I made a cafetiere of coffee this morning, put some milk in my cup, then poured the brewed coffee into the cup. I noticed that the coffee fizzed a little and seemed to 'dance' on the surface making some little splashes that were separate and disconnected from the pouring action. I only noticed this when the mug was 3/4 full up until it was full.
What's going on?
Is it the fat in the milk? An acid/alkaline reaction? Cold vs hot? A quick search of the interwebs failed me, so I thought I'd ask the PH mindhive.
P.s. the coffee tastes great!

It could be to do with your water supply.
My brother lives in an area where United Utilities were trying out different sources of water such as boreholes etc, and depending on the mix of water sources, the public were experiencing water 'fizzing' and also popping and banging loudly in kettles as it was boiled.
The problem was so bad that the public were going out and buying new kettles as they thought theirs had become seriously defective.

Thanks for the replies, oddly enough it didn't do it this morning! Just to clarify, I don't have fizzy water taps...but I wonder if its some dishwasher detergent not getting properly rinsed off the cups..
it may be the 'salt' or rinse aid in the dishwasher tablet/gel.Very interesting observation and comments. I have been using Tesco Ashbeck bottled still water for a few years now for kettle boiled water. It has a very low calcium count and creates zero scum/hard water deposits in the kettle - highly recommended if not a little indulgent (although I do live in a hard water area).
