Which matters more for milk drinks, cappuccino wet or dry, when comparing pour-over and Americano?
Pour-over and espresso are the two main brewing methods, and their extraction principles differ. Pour-over uses atmospheric pressure drip filtration, much like brewing tea, and gives a clean, refreshing cup. Espresso uses high pressure for fast extraction, yielding a small volume of concentrated liquid that is then diluted to make an Americano.
Most beans on the market are developed for one of the two uses, so roast level and blending follow the method. Pour-over gear includes a gooseneck kettle, dripper and filter paper, server, grinder, scale and thermometer. Espresso parameters land in a different range, and that gap shapes strength and sweetness in the cup.
Pour-over coffee and espresso are the two most mainstream brewing methods today, and most coffee beans on the market are developed around these two uses. Their extraction principles are completely different: pour-over is atmospheric pressure drip filtration, similar to brewing tea, with a clean and refreshing taste; espresso uses high pressure for rapid extraction, producing a small amount of highly concentrated espresso. Beyond differences in equipment and parameters, the roast level and blending approach of the coffee beans used also have their own considerations. This article will systematically sort out the differences between pour-over and americano, from extraction principles, operational key points, parameter adjustments to specific serving methods, and answer which is stronger and which is sweeter, while sharing Front Street Coffee's practical experience in bean selection and making americanos.
Currently, pour-over coffee and espresso can be considered the two most mainstream brewing methods, and coffee beans in the consumer market are almost all developed around these two uses. The extraction principles of pour-over and espresso are completely different: pour-over belongs to atmospheric pressure drip extraction, and the process is somewhat like brewing tea, with a flavor profile that tends to be refreshing; espresso is pressure-enhanced extraction, using high pressure to squeeze out the coffee substances, resulting in a small amount of rich coffee liquid. The raw materials used (that is, coffee beans) and the direction of extraction parameter adjustments also differ between the two.
So-called pour-over coffee is made by first grinding coffee beans into powder, then pouring hot water so that it contacts the coffee bed and "dissolves" the soluble substances in the coffee. Essentially, it uses a dripper with filter paper or other tools to intercept the coffee grounds and keep them from mixing into the server, thus obtaining a cup of clear black coffee. Based on Front Street Coffee's brewing experience, to complete a pour-over, besides coffee beans of passable quality, Front Street Coffee believes at least the following equipment is needed: a gooseneck kettle for pouring water, a dripper and filter paper for filtering coffee grounds, a server, a grinder, an electronic scale that can record water amount and time, and a thermometer to measure water temperature.
Drip coffee extraction takes a long time, usually at least several minutes. In order to obtain a cup of rich coffee in a short time, Italians came up with the idea of using steam pressure to let high-temperature, high-pressure water pass through the coffee puck, thereby speeding up the originally drip-style extraction. Through continuous improvement, this gave rise to the semi-automatic or fully automatic espresso machines we are familiar with. When extracting with an espresso machine, first grind the coffee beans into powder, tamp them into the portafilter, then use high pressure to push hot water through the coffee grounds and extract a cup of full-bodied espresso. Because the concentration is very high, it is usually diluted with water or milk before drinking. Common americanos, lattes, and cappuccinos are all made with espresso as the base.
Although the operation does not look complicated, when extracting with an espresso machine, to make the soluble flavor substances in coffee release into the hot water in just a few dozen seconds, the contact between coffee and water must be more sufficient, and the grind size must be very fine and uniform, so it places great demands on coffee bean quality and the barista's skill. Many factors affect the flavor of a cup of espresso, including coffee bean quality, roast level, grind size, espresso machine boiler pressure, water temperature, distribution and tamping force, dose, extraction time, yield, and other details. In daily extraction adjustments, the four most commonly used factors are dose, time, yield, and grind size. Brewing parameters will change slightly with daily air humidity and the condition of the coffee beans, so fine adjustments up and down are needed to achieve a more ideal extraction result.
Friends who have come to Front Street Coffee's store to drink coffee should have seen Front Street Coffee's bean list blackboard. The nearly fifty single-origin coffees on it are categorized by different producing regions, and Front Street Coffee serves them all as pour-over or cold drip; while for making espresso, Front Street Coffee uses only one house-roasted "Sunflower Warm Sun Blend," with flavors of vanilla, cream, berries, caramel, and fermentation. If light-roasted single-origin pour-over beans are used to make espresso, under finer grinding and high pressure, the taste will become intense and concentrated, and negative bitterness, acidity, and astringency are likely to appear. Therefore, for these two different extraction forms, pour-over and espresso, Front Street Coffee suggests choosing corresponding coffee beans separately.
Pour-over allows people to appreciate the most authentic aroma and flavor of black coffee. If you are just starting out, Front Street Coffee suggests first using cost-effective coffee beans to practice, because on one hand it is easier to start understanding major producing regions through regional flavors, and on the other hand it can also avoid waste caused by operational mistakes.
On Front Street Coffee's bean list there is a daily drinking bean series. So-called daily drinking beans are tasty but not expensive. Front Street Coffee has selected 7 classic origins, covering multiple highly representative producing regions, varieties, and natural processing methods, including Ethiopia's washed Yirgacheffe, Guatemala's washed Huehuetenango, Colombia's washed Huila, Brazil's semi-dry Cerrado, Costa Rica's washed Tarrazu, Indonesia's wet-hulled Lintong Mandheling, and China Yunnan's washed Baoshan. At an affordable price, you can taste the flavor tone of each producing region and thereby confirm your own coffee preferences. It is a very cost-effective series from Front Street Coffee.
Espresso is extracted under fine grinding, high water temperature, and high pressure, and the concentrated liquid gathers multiple tastes, with various flavor compounds impacting the taste buds exponentially. Coffee is ultimately an agricultural product and will change with climate, soil, and other conditions. Even if it comes from the same place, the flavor of each batch of beans will differ. Blended beans ensure a balanced and stable aroma and mouthfeel every time by complementing each other's strengths. Front Street Coffee's classic espresso blend coffee beans are recommended, rich in crema, with aromas of chocolate, roasted nuts, and cream.
When serving americano, Front Street Coffee first grinds the coffee beans into powder, extracts espresso at a 1:2 coffee-to-liquid ratio, then pours it into water to dilute, that is, using 20 grams of coffee powder to extract 40 grams of coffee liquid. After many tests and adjustments by Front Street Coffee, a 1:6 ratio of espresso to water best showcases the coffee aroma, that is, pouring 40 grams of coffee liquid into 240 grams of 88℃ hot water, and the hot americano is complete.
If making iced americano, replace the hot water with 120 grams of ice cubes plus 120 grams of room-temperature water, and the taste is best when drunk before the ice melts. Front Street Coffee's iced americano is icy and refreshing with a sweet, mellow taste, making people exclaim how satisfying it is after drinking it.
