On coffee shop menus, the term "single-origin coffee" is appearing more and more often, but do you really understand it? Many people assume that choosing coffee beans from a certain country makes it single-origin, but true single-origin coffee emphasizes a specific producing region—that is, the very source of a cup of coffee.

However, today the flavor of single-origin coffee also incorporates the roaster's personal style, and is no longer entirely equivalent to the original taste of the producing region. This article will help you sort out the definition of single-origin coffee, the distinction between it and the specialty coffee classification, and explore how roast level and brewing method affect the final flavor in the cup, helping you have more direction the next time you order.

Planning purchases and drinking according to the roast date makes it easier to get a cup that meets expectations than looking only at origin or flavor descriptors. [more…]

This article will take you through the story and professional details behind this innovative process. [more…]
