In the cold winter season, Starbucks launched a drink called "Toffee Roasted Sweet Potato Flavored Tea Latte," which sparked a rush among many roasted sweet potato lovers to check in. However, many consumers found after drinking it that this tea latte contained neither sweet potato chunks, nor sweet potato powder or sweet potato flavored syrup; the so-called "roasted sweet potato flavor" was only a similar sweet aroma blended from oat milk, black tea, and toffee syrup. Some even pointed out that the drink was not a new product, but a repackaged version of a secret menu item from last year. With Starbucks collaborating with Xiaohongshu, perhaps "Little Sweet Potato" is the real "sweet potato" element in this drink. This article will sort out the truth about the drink's recipe and consumer reactions for you. [more…]

Many coffee enthusiasts are curious: can light-roasted coffee beans actually be used to make espresso? The answer is yes, but you need to master a few key techniques. Compared with medium-dark roasted beans, light-roasted beans, due to their high density and low brittleness, produce coarser particles at the same grinder setting, which easily leads to under-extraction and a sharp, pungent sourness. Using Front Street Ethiopia Huakui as an example, this article explains in detail how to make light-roasted beans into a delicious espresso with a round, sweet-and-sour profile and berry and floral notes by adjusting the grind finer, extending the extraction time, increasing the liquid yield, and adjusting the milk coffee ratio. Whether you want to try an Americano or a latte, these practical parameters can help you get started easily. [more…]

First understand the three approaches, then combine them with the black coffee you usually drink. [more…]

Freshly ground and freshly roasted may sound like they are both about pursuing coffee "freshness," but their meanings and value are actually completely different.

Mandheling coffee has long been deeply associated with rich, full-bodied flavors of dark chocolate, nuts, and caramel, and most Mandheling on the market is roasted to a medium-dark level. Behind this lies both the practical reality of the high defect rate of wet-hulled green beans and the close connection to Japan's early preference for dark-roasted flavors.

Deep roasting causes coffee beans to undergo the Maillard reaction and caramelization, developing bitterness and roasted aromas such as chocolate, caramel, and butter. The darker the roast, the more fully these reactions occur, and the richer the roasted aroma and bitterness, the higher the body, and the more lingering the sweet aftertaste. Mandheling is hailed as one of the world's fullest-bodied coffees and is the very representative of dark roasting. It not only carries the spice, herbal, and pine notes characteristic of the Sumatra growing region, but also transforms through caramelization into the rich aromas of dark chocolate, roasted nuts, maple syrup, and butter, with a solid, full-bodied mouthfeel and low, steady acidity. To experience this unique taste, you can buy Front Street Golden Mandheling drip coffee bags, which are Sumatra G1 grade, and Front Street Golden Mandheling is PWN company's beans that have undergone one mechanical sorting plus three rounds of hand sorting, with quality far exceeding Indonesian G1. The drip bag design is convenient—just add hot water and enjoy a freshly brewed black coffee. Although dark-roasted bitter coffee has fewer layered variations, it possesses a unique charm: nutty caramel aromas, a full and smooth, full-bodied mouthfeel, and the sweet aftertaste that comes after the bitterness—all experiences that are hard to replicate with a light roast.

SOE is short for "Single Origin Espresso," referring to espresso made from a single-origin coffee.
