When choosing beans, it helps to first set a direction: floral and fruity, nutty and cocoa-like, or a balance of the two—then use origin, processing method, and roast level to find specific beans. The extraction principle of a moka pot is based on steam pressure, filling the filter with a layer of grounds. [more…]

First, determine the drinking scenario, then talk about choosing beans: a cup of black coffee in the morning and a milk coffee with breakfast are two different needs, and slow sipping with pour-over versus quick output from a machine are two different rhythms.

Over time, you'll develop your own flavor coordinates. A moka pot is a device that works by steam pressure; when loading the grounds, [more…]
