News: Starbucks tests the Cold Foam Mocha in Nashville; Root Beer in Atlanta & Austin:
As I understand it, a special “cold foam” is prepared in advance in whipped cream canisters. Shots of espresso are poured into milk steam pitchers with the right amount of ice in it, and then the espresso is stirred. Then the cold espresso is poured over the “cold foam” in the cup. In other words, it seems as though the steps might be this. Place correct amount of cold foam into plastic cup. and add in the right amount of mocha (or white mocha). Place the right amount of ice into milk steaming pitchers. Add shots and stir a little, and then pour over the cold foam.
