The charm of a Dirty coffee lies precisely in that clear layering between the coffee and the milk. Only when layering is achieved can the drinker experience, in a single cup, the rich progression from intense to mellow; otherwise, it is nothing more than an iced latte without the ice. The basic principle behind layering is not complicated: the density of the lower liquid must be higher than that of the upper liquid, and the difference in density between the two creates the layering phenomenon. In practice, however, there are quite a few factors that cause layering to fail, and this article analyzes one by one the various reasons that affect the layering effect. First, let us start with the concentration of the coffee liquid. Many enthusiasts, limited by their circumstances, try to use coffee brewed with a moka pot to make a Dirty, but the concentration and density of coffee from a moka pot fall far short of the espresso extracted by an espresso machine, so it is not suitable as the espresso base for a Dirty.

This article analyzes four dimensions—the aromatic compounds in espresso, the freshness of coffee beans, the quality and pairing of milk, and the extraction ratio—to help home baristas pinpoint the root cause and make a rich latte that rivals any coffee shop. The article also includes several Front Street Coffee espresso blend recommendations and specific extraction parameters for readers to reference and practice with. [more…]
