After the holidays, many people rely on coffee to "stay alive," only to find they're still sleepy after drinking it.

Starbucks recently announced that it will launch the Olive Oil series in selected stores nationwide, including two olive oil coffee beverages. This series is actually Oleato, which was introduced to China a year late—a "groundbreaking" creation once strongly promoted by former Starbucks CEO Howard Schultz. From Dongpo pork latte to olive oil coffee, Starbucks has launched frequent new products this year but has also sparked continuous controversy. Some people have placed olive oil coffee on the "dark coffee" list, while others have been conquered by its peculiar taste, and even more consumers have become fans due to its laxative effect.

Coffee is not just a pick-me-up beverage—in recent years, research has also found that it has potential benefits for the digestive system. A 2023 systematic review and meta-analysis published in the journal Nutrients, which included more than 430,000 participants, explored the association between coffee intake and the risk of irritable bowel syndrome (IBS). The results showed that, compared with non-coffee drinkers, people who drank coffee had a 16% lower risk of developing IBS. This protective effect may be related to the antioxidant and anti-inflammatory properties of components in coffee such as caffeine, polyphenols, diterpenes, and trigonelline. However, the effect of coffee on relieving IBS symptoms varies from person to person, and the study itself has observational limitations. This article will provide a detailed interpretation of this study and explore the possible effects of coffee on gut health. [more…]

Naobaijin has once again made its presence felt in the coffee world. This time, it's not just a simple co-branded paper cup—they've actually added Naobaijin oral liquid to the coffee.

Many friends who are just getting into pour-over coffee go through a phase like this: standing in front of the coffee bar, eyes fixed on the barista's every move, trying to replicate a good cup of coffee by imitation.

Guming obtained approval for a Hong Kong listing filing, becoming the first company to receive the green light amid the new tea beverage IPO wave. Meanwhile, its winter new product "Dark Chocolate Mocha" has drawn attention for its rich cocoa flavor, but has also been jokingly called a "great gut cleanser" due to a large number of consumers reporting diarrhea after drinking it.

To consistently produce top-tier espresso at home or behind the bar, a good machine alone is far from enough. What truly determines the flavor in the cup are four key links starting with M: the blend (Mistura), the grinder (Macinino), the machine (Macchina), and the barista (Mano). This article begins with the pairing of coffee bean types and explains in detail how to adjust the grind setting, control the level in the bean hopper, master the machine's pressure and water temperature, and pace the barista's movements so that 7 grams of grounds extract 20 to 35 milliliters of ideal espresso in 20 to 30 seconds.
