Whether a cup of coffee tastes good or not, freshness is often the decisive factor. No matter which country the coffee beans come from, which factory roasts them, or which channel sells them, freshness preservation is always the top priority.

So how can ordinary consumers judge whether the coffee beans in their hands are fresh enough? This article starts from seven dimensions—looking, grabbing by hand, smelling, pressing by hand, biting, grinding, and brewing—and breaks down the identification methods one by one, helping you quickly make a judgment in daily purchasing and use, and grind out truly good-tasting coffee.

Crema is the signature characteristic of espresso. This layer of golden oil is composed of insoluble fats wrapping carbon dioxide, and can only be formed through the high-pressure extraction of an espresso machine. The richness of the crema is closely related to the coffee bean blend; Italians often add a small amount of Robusta to enhance the crema, but Robusta does not match Arabica in flavor. Both Front Street Classic Blend and Front Street Commercial Blend contain a small amount of Robusta—the former is suitable for home beginners, while the latter is suitable for commercial use in shops. However, more crema is not necessarily better. If the color is too light or too dark, the thickness too thin or too thick, or the crema clumps and appears rough, all of these can affect quality and latte art results. Beans that are too fresh can instead lead to unstable crema. [more…]

When brewing pour-over coffee, the filter cup actually holds quite a few clues. The size of the dome that the coffee bed puffs up into during the blooming stage, and how well it retains water, can reflect the freshness of the coffee beans and the depth of the roast; whether the coffee bed can be lifted indicates the density of the coffee grounds; the color change of the foam on the surface can help us track the pouring path; and the speed of the drawdown is related to the coarseness of the grind, the density of the coffee bed, and fine particle clogging. As for the deep coffee bed pit that many beginners obsess over, it does not directly equate to a better-tasting cup; it is more just a reflection of the pouring method. In this article, Front Street will break down these readable pieces of information one by one during the brewing process, to help you have a few more bases for judgment when adjusting parameters.

Bagged coffee only needs to be placed in a container with liquid added, and is suitable for both hot and cold, and can even be steeped in coconut milk or fruit wine for a different flavor; drip bag coffee is closer to a simplified version of pour-over, with requirements for water temperature, pouring technique, and freshness.
