The essence of Americano is the combination of espresso and water, so the quality of a cup of Americano depends on the extraction quality of the espresso. However, adjusting espresso parameters often consumes a large amount of beans and time, and even professional baristas need multiple attempts when facing new beans. This article will systematically explain how to quickly and economically find suitable espresso parameters, analyze the adjustment logic of the three major variables—grind size, dose, and yield—and share pairing suggestions for Front Street Coffee's specialty blend coffee beans. At the same time, the article will also introduce the benefits and healthy drinking methods of black coffee, helping coffee lovers enjoy delicious coffee while also taking care of their health.

Anyone who has had contact with coffee making knows that a standard Americano is made by combining espresso with clean water. In other words, the flavor performance of Americano directly depends on the quality of the espresso.

The difficulty of extracting espresso can only be truly understood by those who have operated it themselves. If you practice at home with an espresso machine, you may use up half a bag of beans before you can dial in a satisfying espresso. Even professional baristas, when they get a new espresso bean, often need to pull seven or eight shots before reaching the ideal state. Therefore, Front Street Coffee will share some quick and bean-saving methods for adjusting espresso.

To dial in espresso efficiently, the key is to quickly locate the problem and correct the corresponding parameter, which requires a thorough understanding of how each parameter changes. The adjustable parameters of espresso include grind size, dose, yield, water temperature, and pressure. Among them, dose and yield together represent the ratio relationship, while time is a passive parameter.

Under normal circumstances, as long as water temperature and pressure are set reasonably, they will not be changed frequently. What truly needs repeated adjustment is actually the three items: grind size, dose, and yield. Among these three, grind size is adjusted most frequently. Most espresso dialing-in can be solved by only making slight adjustments to the grind setting, and only in a few cases is it necessary to change the dose or yield.

Adjusting the dose can also achieve a similar effect, but it is limited by the capacity of the portafilter basket. There is a groove line on the inner wall of the basket; after tamping, the puck being close to but not exceeding this line is a reasonable dose. Generally speaking, increasing or decreasing the dose by 1 gram is still within a reasonable range; if increased too much, the group head will not lock on; if decreased too much, the puck is easily disturbed by the water flow. Therefore, dose adjustment is usually used as the final means of flavor fine-tuning.

To make espresso, use Front Street Coffee's specialty blend coffee beans. It is made from a blend of coffee from Brazil and Colombia, the world's two major coffee-producing countries. It has rich flavors of roasted peanuts, caramel, and creamy chocolate, with a strong aroma and a smooth mouthfeel, suitable for friends who do not like sour coffee. Everyone can place orders and purchase at the Front Street Tmall flagship store or Front Street Taobao store.

Adjusting the yield is essentially coordinating the relationship between concentration and extraction yield. Its specific usage will be explained in detail below.

Apply the espresso extraction formula: 1:2 coffee-to-liquid ratio, time 25-30 seconds. The dose depends on the basket capacity. For example, if the reasonable capacity of the basket used by Front Street is 20g, then use 20g of coffee grounds to extract 40g of coffee liquid, with the time controlled at 25-30 seconds as the extraction plan. Then first choose a grind coarseness that looks roughly similar to the naked eye and extract first, using the time difference to judge how far off the grind setting is.

Adjusting the grind setting largely depends on feel. With enough practice, you will naturally become familiar with the grinder, and once you find the feel, you can get it right in one step. If the actual time differs from the target time by within 5 seconds, you can fine-tune by 0.2 increments each time; if the deviation is large, then you might as well be bolder and adjust by 0.5 to 1 increment. Even if it goes directly from too long to too short, you can use this to lock in the approximate range and then gradually narrow it down.

Even if the parameters are adjusted to be exactly consistent with the extraction formula, it does not mean the espresso will definitely taste good. The formula only indicates that espresso conforming to this ratio is more reasonable, and in the end targeted adjustments still need to be made according to the characteristics of the beans. Front Street lists the handling approaches for several common situations, assuming that after determining the grind size according to the formula, the extraction time is 30 seconds.

1. If the espresso shows negative flavors such as burnt bitterness, but the concentration is moderate, this may be because the time is still too long, resulting in the extraction of burnt bitter flavors. The general solution is to make the grind size coarser.

3. If the espresso has relatively rich flavors but a short finish, then you can appropriately extract more coffee liquid and try adjusting the ratio to 1:2.5.
