The core of coffee's alertness-boosting effect lies in caffeine, but different coffee bean varieties and extraction methods can cause significant differences in the caffeine content of the final drink. Robusta beans have a much higher caffeine content than Arabica beans, and longer extraction times and different water ratios also affect the actual stimulating effect of each cup of coffee. Espresso may seem intense, but its caffeine content is not necessarily the highest; pour-over, French press, cold brew, and ice drip often contain more caffeine due to longer contact time. From the perspective of Front Street Coffee, this article systematically sorts out coffee bean varieties, extraction methods, and the caffeine content of common drinks, helping you choose the most suitable stimulating coffee for yourself in different scenarios.

Many coffee enthusiasts are in the habit of starting the day with a cup of coffee, but do you really know how much caffeine you're drinking? People often assume coffee is the drink with the highest caffeine content, but that's not actually the case—tea leaves actually contain twice as much caffeine as coffee beans. So how much caffeine do different varieties of coffee beans really contain? How much is in a cup of pour-over, cold brew, or espresso? And how much caffeine per day is safe for an adult? This article starts with coffee bean varieties, breaks down the caffeine content of each brewing method one by one, gives practical figures based on extraction efficiency, and finally answers the popular question of how many cups of coffee you can drink per day at most. Front Street Coffee store information is included at the end of the article for readers' reference. [more…]

Many people choose to drink coffee with the core desire of consuming caffeine. Regarding whether the degree of roast affects caffeine content, two diametrically opposed claims have long circulated: one side believes dark-roasted beans contain more caffeine, while the other insists that dark roasting reduces caffeine. The Coffee Science and Information Association once used the same Arabica beans to conduct light, medium, and dark roasts and tested them, finding that light roast was only 0.06 percentage points higher than dark roast. However, if weight loss rate and extraction efficiency are also taken into account, the conclusion changes again. The real key determining caffeine content actually lies in the bean variety itself. This article will break down these variables layer by layer to help you clarify the true relationship between roast level and caffeine. [more…]

Many people believe that dark roast coffee tastes more bitter, and therefore assume it contains more caffeine. But is that really true? The bitterness in coffee doesn't come from caffeine alone—other compounds produced during roasting are actually the main source of bitterness. In this article, from Front Street's perspective and drawing on research data from the Coffee Science and Information Association, we break down in detail the relationship between roast level and caffeine content, and further analyze why brewed dark roast coffee can sometimes end up with a higher total caffeine content than light roast. Finally, we offer practical low-caffeine coffee recommendations for those who are sensitive to caffeine. [more…]

Following the case of Shuyi Burning Grass Jelly, the Shanghai Consumer Council on March 13 once again turned its attention to the internet-famous tea beverage brand More Yogurt, focusing on the ingredient composition of its "Mango Yogurt Smoothie." Testing by the Consumer Council found that the drink contained only a small amount of yogurt yet had unusually high fat content, and despite being labeled as having no added sugar, sucrose and maltose were still detected. The Consumer Council questioned the source of this excess fat and sugar and demanded that More Yogurt explain to consumers "what was added." The incident quickly sparked widespread discussion and trended on Weibo. This article sorts through the testing data and science popularization information released by the Consumer Council to present the full picture of the incident. For readers interested in coffee and beverage industry trends, Front Street Coffee also continues to follow such food safety topics and advocates transparent consumption. [more…]
