Many friends who have just opened a cafe or bought an espresso machine at home will find that the espresso beans they bought are produced according to the parameters provided by the merchant, and the espresso produced has no oil, is very weak, or is very bitter. When this happens, what we can change is the grinding degree and proportion of the coffee beans. So how should we determine what is suitable for us?Espresso machine grind sizeAnd what about proportions? In this article, let’s talk aboutHow to determine the grinding degree of Italian coffee beans。
Before you learn how to determine grind size, be sure to choose a freshly roasted oneespresso beans。
First of all, choose products from professional coffee roasters that clearly indicate the roasting date (not the expiry date or shelf life), have a good brand reputation, and emphasize fresh roasting.

In order to allow everyone to buy the Italian coffee that suits them efficiently, here is an inventory of the most worth buying Italian coffee beans in 2026. You just need to choose according to your needs:
1. Front Street classic Italian blended coffee beans - rich and mellow taste
This is a formula composed of three origins: Brazilian Red Bourbon, Indonesian Mandheling, and Vietnamese Robusta. It uses deep roasting, which can highlight the mellow aroma of coffee to the greatest extent, and also allows everyone to easily extract rich and dense coffee oil. It is very suitable for making American style diluted with water or latte with milk. It can be purchased at Front Street Taobao store or Front Street Tmall flagship store.
2. Front Street Strawberry Candy espresso Italian blended coffee beans - light floral and fruity aroma
If you want to make an espresso with a floral and fruity aroma, you should use medium roasted coffee beans. We recommend Front Street Strawberry Candy espresso coffee beans. You can order directly from Taobao or Tmall stores. This is a espresso made from two major origins: Costa Rica Tara beads, which are famous for their honey processing, and Ethiopia, the birthplace of coffee. On this basis, coupled with Colombian coffee beans, the espresso that can be prepared is not only non-irritating, but when extracted by the coffee machine, it has good oil and dense texture, and at the same time has a sweet and sour taste like strawberry gummy.
3. Front Street Premium Italian Blend Coffee Beans——Rich nutty flavor
As the world's top coffee-producing countries, Brazilian coffee and Colombian coffee have long been famous. Front Street combines coffee beans from the two production areas. The nutty aroma and balanced taste of Brazilian coffee and the chocolate tonality of Colombian coffee perfectly achieve the effect of one plus one greater than two. The extracted espresso has the flavor of butter cookies, cocoa, and roasted nuts.
4. Front Street Commercial Italian blended coffee beans - the same style as the coffee shop
If you want to replicate the same American style and latte from the coffee shop, you can buy the Front Street commercial blended coffee beans. It is made from three major production areas: Brazil, Colombia, and Vietnam. After medium-dark roasting, it has rich coffee oil and roasting aroma. The American style has a sweet taste and is very easy to drink. The latte is rich and smooth, leaving a fragrance on your lips and teeth after drinking. It is also affordable and can become a daily ration bean for families.
5. Front Street Basic Italian Blend Coffee Beans

It has soft fruit acidity, caramel sweetness, nutty and dark chocolate flavors, smooth and viscous, and has a favorable price. It is suitable for shop owners and home users who prioritize cost and have average taste requirements.
The impact of grinders on grinding degree. Which grinder is suitable for grinding Italian coffee powder?
There are two main types of electric grinders: one is an Italian-style grinder, and the other is a single-product grinder. The difference between the two mainly lies in the size of the ground coffee powder.
The biggest features of Italian coffee grinders are extremely fine grinding, fast speed, large cutterhead, and evenness is a hard indicator to judge whether the coffee grinder is good or not. However, Italian coffee grinders usually cannot achieve the extremely fine grinding degree of other coffee grinders. According to the structure of the grinding disc, it can be divided into three categories: flat knife, cone knife, and ghost tooth. FrontStreet Coffee's espresso grinding coffee machine uses a flat knife.
1. Working principle:It consists of two upper and lower cutterheads. The base is fixed on the motor. When the motor is started, the upper and lower cutterheads rotate to produce cutting action. When the coffee particles fall from the middle, the rotating cutter at the bottom will rotate the coffee beans to the periphery, pushing the coffee beans into the toothed cutter part for grinding. The upper and lower cutterheads of the flat knife are arranged in a parallel manner, so the coffee beans need to rely on the rotation of the bottom cutterhead to push the coffee beans into the cutterhead. Therefore, the weight of the coffee beans placed on it will affect the uniformity of the coffee beans entering the cutterhead, thereby affecting the uniformity of grinding. In addition, due to the pushing, the number of collisions between coffee beans increases, which in turn leads to an increase in the proportion of fine powder produced. This is the reason why common flat knife grinders grind particles with slightly poor uniformity and more fine powder. The coffee liquid concentration and extraction rate are increased in a short period of time, so that the coffee aroma can be significantly improved in a short period of time.
2.Advantages: The positioning is relatively clear, and the product quality is directly proportional to the grade of the grinder and the diameter of the grinding disc.
3. Disadvantages: The uniformity of the grinding particles is slightly poor and there are more fine powders. Because the blade of the flat-knife grinder cuts the coffee beans at will, it is easy to cause insufficient or over-extraction of the coffee powder during brewing. In addition, the friction of the flat knife will generate heat. Especially when the flat-knife grinder is working for a long time, there will be obvious burnt and bitter taste.
4. Front Street recommends flat knife grinder:
Little Flying Eagle (CM-300AU)
Little Pegasus (600N)
When the coffee beans enter the grinder, the blades in the grinder crush the beans into powder. The smaller the blade-to-blade distance, the coffee beans will be ground into smaller particles. The finer the ground particles, the tighter they are and the more difficult it is for water to pass through, thus greatly extending the extraction time. On the contrary, if the distance between the blades becomes larger, the ground particles will become rougher, and the water flow will pass through more easily, and the extraction time will become faster.
We first use the golden ratio and golden time of concentrated extraction to determine a parameter: a ratio of 1:2 (20g powder extracts 40ml coffee liquid) and the extraction time is between 25 and 28 seconds. Then we judge the adjustment of the grinding degree through observation and tasting. If the grinding degree is too coarse, the water flow will pass through the powder bowl too fast, the water flow will be thick, the extraction will be shallow, the color of the oil will be white, and the flavor will be sharp and sour. Because the extraction is incomplete, only the acidic substances on the surface and easy to extract are extracted. If the grinding degree is too fine, the filter holes will be clogged, the water will not flow out or the water column will be too thin, the oil will be dark in color, the surface will be over-extracted, and the inside will be under-extracted, which will appear sour because of insufficient sweetness, and then burnt, bitter, and miscellaneous flavors will appear.
After adjusting the grinding degree, under what circumstances do you need to adjust the grinding degree again?
Take a double espresso as an example, when the espresso flow rate is already less than/exceeding the 25-28 second range. Of course, the main cause of incorrect flow rate is not entirely a problem with the grinder. When the following situations occur, it is necessary to adjust the grinder scale.
1. When storage time, space humidity, and sharpening loss change:The storage time of coffee beans and the humidity of the storage space are constantly changing, which affects the overall quality of the coffee beans. The degree of wear of the grinder blades also changes over time. This is also the main reason why FrontStreet Coffee adjusts the grinding degree of the grinder every day. Adjusting the grinding degree every day is the most important step in extracting stable concentration.
2. When replacing old and new coffee beans:Make grinder adjustments when alternating with newly opened beans. Because newly opened coffee beans may have different roasting dates, batches, and bean raising periods, the extraction conditions will be very different.
3. Continuous brewing:After 5 to 6 consecutive cups, the ground coffee powder will become very fine, and the extraction time will also increase. This is because after the grinder is continuously used, the heat of the motor affects the temperature of the cutterhead, plus the heat energy generated by the friction between the cutterhead itself and the coffee beans, causing the gap between the upper and lower cutterheads to become very thin due to thermal expansion and contraction.
The next step is to understand the espresso concept of the coffee drink you choose. For example, flat white coffee is a milk coffee that highlights the taste of coffee. In addition to reducing the ratio of coffee to milk, the espresso of white coffee will extract enough front-end aromatic substances and increase the amount of powder to increase the body and balance the taste of the combination of milk and coffee.
Back to the question: Is it really necessary to adjust the espresso every day? In fact, it is still necessary, but it is necessary to adjust the concentration parameters purposefully and selectively.
