In the brewing process of specialty coffee, the coffee-to-water ratio and the coffee-to-beverage ratio are two core concepts that cannot be avoided. Many people assume they are simply different names for the same thing, but in reality their calculation methods and applicable scenarios differ significantly. This article will start from the basic definitions of these ratios, first explaining the meaning and advantages of the coffee-to-water ratio, then delving into why the coffee-to-beverage ratio cannot be directly equated with the coffee-to-water ratio, and, combined with the water absorption rate of coffee grounds, provide a practical conversion method. Once you understand these two parameters, you will have clearer direction when adjusting your brewing recipe, and it will be easier to consistently reproduce your ideal flavor performance. [more…]

Before making pour-over coffee, is it really necessary to rinse the paper filter with hot water? This question has long been debated in the coffee community. Some insist that wetting the filter removes papery taste, helps the filter adhere better to the dripper, and preheats the dripper along the way; others believe that modern filter manufacturing has advanced so much that these reasons may no longer hold. This article, from Front Street Coffee's perspective, examines one by one whether the three traditional advantages of wetting the filter still stand, and takes a deeper look at how the water-absorbing properties of a dry filter affect coffee strength, as well as the pre-extraction issues that may arise when coffee grounds come into contact with water early. The final conclusion may surprise you—the difference between a wet and dry filter is actually negligible. [more…]

Many friends who are just getting into pour-over coffee often confuse the coffee-to-water ratio with the coffee-to-beverage ratio, and as a result, the coffee they brew always tastes different from what they expected. In fact, although these two concepts differ by only one word, their meanings are completely different, and they cannot even be converted directly on an equal basis. Today, Front Street will explain these two measurement methods, first explaining what each of them represents, then clarifying how the coffee grounds' water absorption affects the final liquid weight, and offering a way to convert between the coffee-to-water ratio and the coffee-to-beverage ratio. Once you understand these, you will have a clearer direction when adjusting pour-over parameters, and it will be easier to consistently reproduce a delicious cup of coffee. [more…]

Blooming is a key step in pour-over coffee brewing that cannot be overlooked, as it directly affects whether the subsequent hot water can evenly pass through the coffee bed. This article provides a detailed analysis of the difference between blooming and pre-infusion, explains the dual purpose of blooming—releasing carbon dioxide and forming an even filter layer—and offers specific recommendations for the amount of blooming water, typically 1 to 2 times the weight of the coffee grounds, along with the reason for keeping the water temperature between 85 and 92 degrees Celsius. At the same time, the article also explains the blooming pouring technique from three dimensions—small amount, even, and gentle—and points out the differences in water absorption among beans of different roast levels. Front Street Coffee reminds us that only sufficient and proper blooming can lay the foundation for subsequent even extraction, making the flavor of a cup of pour-over coffee more pleasant. [more…]

Without adding sugar or milk, how to hand-brew a delicious and distinctive cup of coffee is a difficult challenge for many enthusiasts just starting out in coffee. Pour too much water and the coffee will be weak; pour too little and it will be very strong and harsh on the throat. Therefore, you must pay attention to the coffee-to-water ratio. So exactly how much water should be used to brew a cup of coffee? The coffee-to-water ratio is probably what every [more…]

The total brew time of a pour-over is shaped by multiple factors at once—grind size, how the particles take on water, the pouring technique, and the design of the dripper—making it very hard to control precisely. Many people new to pour-over habitually use time as the standard for judging whether the flow rate is normal. Once the flow at the tail end of the brew refuses to come down, the extraction time gets dragged out and the coffee easily picks up bitter, off-flavors. This article focuses on the common frustration of standing water at the tail end of a pour-over, analyzing the causes one by one—from the quality of the coffee grind, the roast level of the beans, the pouring technique, and puck management—and offers the corresponding solutions summarized by Front Street to help you find the real reason behind the slow drainage and adjust accordingly.

Indonesia's coffee-growing regions have climate conditions entirely different from those of Africa and Central and South America: year-round humidity of 70–90%, annual rainfall that often exceeds 2,000 mm, and frequent typhoons. In such a humid environment, long-cycle natural process or high-water-consumption washed process are both difficult to carry out. Indonesian coffee farmers therefore developed the distinctive wet-hulling method, which removes the parchment early and speeds up drying, shaping Mandheling's signature full body and herbal, earthy, dark chocolate flavors. This article breaks down each step of the wet-hulling method in detail and includes Front Street Coffee's complete pour-over recipe for medium-dark roasted Mandheling, including dripper selection, grind size, water temperature, and a three-pour technique, helping enthusiasts brew a round, concentrated Southeast Asian flavor at home.

Light roast coffee beans are beloved for their bright floral and fruity aromas, but many enthusiasts often run into slow flow rates and easy pooling when brewing pour-over at home, ultimately extracting nothing but a monotonous sour taste. This actually has a lot to do with the physical structure of light roast beans: with a light roast level, the bean body is dense, the carbon dioxide content is low, and both water absorption and degassing capacity are weak, causing fines to easily settle and clog the dripper. This article will take a deep dive into the difficulties of pour-over brewing with light roast beans, and drawing on Front Street Coffee's brewing experience, share how to effectively enhance the sweetness and complexity of coffee by adjusting water temperature, pouring technique, and staged extraction, so you can consistently brew a well-balanced cup with both acidity and sweetness at home.

In the daily practice of pour-over coffee, many enthusiasts encounter a puzzling phenomenon: when brewing anaerobically processed coffee beans, the drawdown speed is noticeably faster than with regular washed or natural beans, and the extraction time can even be less than a minute and a half. What exactly causes this abnormal flow rate? Is it due to the inherent characteristics of the beans themselves, or is there a problem in the grinding stage? Starting from Front Street Coffee's actual measurement data, this article will take an in-depth look at how the loose texture and vigorous water absorption and degassing of anaerobic beans affect flow rate, and with the help of a comparison of the No. 20 sieve pass-through rate, reveal the deviation between the grinder setting and the actual coarseness of the particles. At the same time, the article will also provide targeted suggestions for adjusting the grind finer and a plan for adjusting the pouring technique, to help you steadily extract a rich, full-bodied cup of coffee even when dealing with anaerobic beans.

Front Street Coffee has previously discussed many factors that influence coffee flavor, starting from five objective conditions: coffee dose, coffee-to-water ratio, water temperature, grind size, and brewing device. This time, however, we turn our attention to an easily overlooked subjective variable—your hand, that is, the pouring method during brewing. This article will break down two major areas: water volume distribution and pouring technique. First, it compares the extraction differences between a single-pour and a three-pour method, then analyzes item by item how blooming, circling speed, pouring height, flow rate, and circling range affect the direction of the flavor. At the end, Front Street Coffee has also selected three single-origin beans with high regional distinctiveness for reference in daily brewing practice. [more…]

In the practice of pour-over coffee, one detail that is often discussed is: should the coffee grounds around the edge be moistened with water? This article starts from the two stages of blooming and the main extraction, and, combined with comparative experiments on light, medium, and dark roast levels, analyzes the impact of the pouring range on flavor. The experiment shows that whether to wet the outer layer of grounds during blooming depends on whether all the coffee grounds can evenly absorb water and release gas in the shortest time. Not pouring around the outer ring tends to cause inconsistent extraction rates, and light and medium roast beans are prone to a grassy, unripe taste; while pouring directly onto the outer ring may block gas release in the center. The article also shares practical techniques such as swirling and stirring to help coffee enthusiasts extract every particle of coffee grounds more evenly. [more…]

The KONO dripper, with its distinctive rib design and slow flow rate, produces a flavor profile in coffee extraction that is completely different from the Hario V60.
