I am another who prefers cold milk in coffee, or black coffee, and yes I think hot milk alters the taste of the coffee. I will drink the occasional cappuccino but was served one recently, in a rather expensive, ‘artisan’ coffee shop, about which the only good thing was the intricate pattern on the top. It was less than lukewarm and was sent back to be remedied. While on the subject of hot milk, can anyone explain to me why, if you tap a cup of hot milk with a spoon, it has a different sound to cold milk, or a cup of any other hot liquid?
