Having a De'Longhi machine in the office is a hard indicator of workplace happiness. But choosing beans for a shared coffee corner and for home follow two different logics: tastes vary and are hard to please, budgets are clearly divided between public and private, and no one takes the initiative to maintain it—the communal nature dictates a bean-selection strategy of "balance first."

Understanding estate traceability takes pour-over bean selection from "choosing a region" to the next level: "choosing an estate." [more…]

When choosing beans for a home espresso machine, the roast level often determines the overall character of a cup more than the name of the origin. Light roasts lean toward aroma and fruity acidity, medium roasts more easily balance sweetness and body, while dark roasts bring notes of cocoa, nuts, and roastiness. When the budget is limited, choosing according to whether you usually drink black coffee, lattes, or iced drinks is usually better than blindly [more…]

When choosing beans, you can first base your decision on [more…]
