In recent years, naturally low-caffeine coffee has been appearing more and more frequently in cafés and at green bean auctions, with varieties such as Laurina, Aramosa, and the newly discovered Ethiopian AC1 attracting considerable attention. AC1's caffeine content is only about 0.76 mg/g, far lower than that of ordinary Arabica. This variety originated from Ethiopian seed resources and was later discovered and studied by the Brazilian Agronomic Institute (IAC) at Santa Elisa Farm. Although AC1 is chemically similar to mainstream varieties and has strong resistance to coffee leaf rust, its low yield and demanding growing conditions pose challenges to its commercialization. The IAC is now developing new varieties with even lower caffeine content and higher yields through crossbreeding. Front Street Coffee continues to follow the latest developments in this field.

Have you ever had this confusion: drinking the same coffee, sometimes you toss and turn, unable to sleep, with a racing heart, while other times it has no effect at all?

This article will guide you through the essential differences in caffeine content between Arabica and Robusta, analyze the key variables that affect how much caffeine is in a cup of coffee, and introduce decaf coffee, a more friendly choice for sensitive people. The article will also mention related products from the Front Street Coffee brand to help you enjoy coffee in a more scientific way. [more…]

The reason coffee can boost alertness lies primarily in caffeine. But when faced with many choices such as espresso, American drip coffee, and single-origin pour-over, which cup has the highest caffeine content and the strongest alertness-boosting effect? The answer depends on two key factors: coffee bean variety and brewing method. In this article, Front Street will start from the perspective of caffeine content, analyze the differences between Robusta and Arabica beans, explain the distinction between naturally low-caffeine coffee and artificially decaffeinated coffee, and, based on the actual caffeine intake per cup, list reference data for common coffee drinks to help you choose the cup best suited for staying alert in different situations.

What exactly is the difference between decaf coffee and regular coffee? Can people who are intolerant to caffeine drink it without worry? And how do the common decaffeination methods on the market change the flavor of coffee? This article starts with a comparison of caffeine content, sorts out the differences between naturally low-caffeine and artificially decaffeinated coffee, breaks down in detail the principles, pros and cons of the sugarcane decaffeination method, the supercritical carbon dioxide process, and the Swiss Water Process, and explains why decaf coffee flavors often lean toward caramel and chocolate notes. If you are looking for a decaf coffee with a mild taste, there is also a medium-dark roast recommendation from Front Street Coffee at the end for reference. [more…]

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 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…]

Excessive caffeine intake can easily cause discomfort such as insomnia and palpitations, with the effects being even more pronounced in people who are sensitive to caffeine. Generally, it is recommended that adults consume no more than 400mg of caffeine per day, roughly equivalent to 5 cups of pour-over made with 15g of beans or 4 cups of espresso made with 20g of beans. If you want to drink more coffee while keeping caffeine intake under control, decaf coffee is the ideal choice. Decaf coffee falls into two categories: naturally grown and artificially decaffeinated. Starting from caffeine content, this article will introduce the natural differences between Arabica and Robusta, and focus on explaining the decaffeination principles and flavor performance of the Swiss Water Process, while also comparing the differences between natural low-caffeine coffee and artificially decaffeinated coffee, to help coffee lovers make a choice that suits them better.

Bourbon Pointu is a rare coffee variety with a natural caffeine content of only 0.5%, named for its narrow, elongated beans with pointed ends. It is naturally low in caffeine due to genetic degradation and has outstanding flavor, but its yield is extremely low and it is susceptible to leaf rust and black spot disease, having once become extinct. In the 18th century, it was highly praised by Louis XV and Balzac, but later disappeared due to disasters, and was only rediscovered and revived in 2001. At the 2018 World Coffee Brewing Championship, Swiss competitor Emi Fukahori won the championship using it, proving its exceptional quality. This article will introduce in detail the characteristics, history, flavor of Bourbon Pointu, and Front Street Coffee's brewing parameters. [more…]
