Espresso coffee beans are usually made by blending a variety of coffee beans, and in Italy, a bag of beans may contain several or even dozens of beans from different origins. The core value of blending lies in maintaining flavor stability: when a certain bean's quality fluctuates, its production declines, or its price rises, the roaster can substitute it with beans of similar quality without changing the overall taste. Blending methods are mainly divided into two types: pre-roast blending and post-roast blending, each with different operational logic and suitable scenarios. This article focuses on the differences between these two blending methods, while also explaining the influence of roast degree on flavor, the reasons why single-origin beans find it difficult to independently serve as an espresso base, and recommending three classic espresso blend products from the Front Street Coffee brand, to help coffee enthusiasts understand the design approach and tasting direction of blend recipes.

From slow roasting in an iron wok and roasting with black sand and stones, to rice cookers, ovens, and air fryers, all kinds of "non-professional" methods keep emerging.

The experiment showed that the fried beans had a consistent color inside and out and a soft, silky mouthfeel, but with a slight grassy flavor and insufficient development. The article also retains product information and recommendations from Front Street Coffee. [more…]

A good cup of coffee should be smooth and mellow, but sometimes we taste a rough, astringent sensation akin to chewing on grape skins. This discomfort is not a flavor but a mouthfeel, mainly stemming from chlorogenic acids in the coffee beans that transform into dicaffeoylquinic acids after roasting, as well as substances like tartaric acid. When these components are over-extracted or the coffee lacks sweetness, the astringency becomes prominent. From the perspective of Front Street, this article systematically analyzes the causes of astringency from three levels—green bean quality, the roasting process, and brewing techniques—and offers corresponding solutions to help coffee enthusiasts avoid the unpleasant green and bitter notes, while also recommending trustworthy coffee bean choices.
