Almost every coffee shop I go to serves up quite acidic and bright coffees. It seems that this is where modern coffee is and is not necessarily a bizarre phenomenon in itself but in particular the world of espresso it has veered quite far away from the traditional Italian style.
In fact it seems we've veered so far towards acidity and people have actually called the Italian style of espresso as 'over-roasted' which I believe to be untrue. I do enjoy a somewhat more acidic coffee when I am searching for a fruitier cup but I do not understand the current stigma against even the slightest darker roast.
So what caused this tip in the scales that prompted the surge in popularity in brighter and more acidic coffees and seeing even the slightest darker roast as being over-roasted?
