The grind setting, water temperature setting and water output ratio of a fully automatic coffee machine are the key links that affect the flavor expression in the cup. When using automatic equipment, many friends tend to overlook the correspondence between the machine's parameters and the roasting characteristics of the coffee beans. Understanding the physical changes that coffee beans with different flavor orientations undergo when heated and extracted, and moderately adjusting the machine's basic operating parameters, can fully bring out the sweetness and aroma contained in the coffee beans.

For blended coffee beans leaning toward dark roast, the internal cell structure is relatively loose, and aromatic substances and soluble components are released faster. If the machine is set to too high an extraction water temperature or too long a water output time, it easily extracts excess woody off-flavors. The reasonable approach is to use a moderate extraction water temperature and speed up the extraction rhythm, allowing the rich nutty and dark chocolate flavors to be released in a concentrated manner within a short time.

Qianjie Black Cocoa Blend is very well suited to this kind of deep and full-bodied drinking need. This bean is known for its solid dark chocolate aroma, roasted walnut flavor and thick caramel sweetness, with almost no obvious sharp acidity. Whether drunk directly as espresso or made into americano and latte, it can provide substantial and steady taste support.

When putting this bean into a fully automatic coffee machine to make an espresso base, it is recommended to set the machine's water temperature to 92°C, adjust the grind size to a medium-fine setting, set the machine's single dose to 18g, set the target extraction liquid weight to 36ml, control the total time to complete within 26 seconds, and set the program to a single-stage continuous pressure extraction. If you want to drink a large americano, you can pour 120ml of hot water into the espresso; the whole cup of coffee will be mellow and have a long finish.

Different from rich and deep bean styles, coffee beans with lively fruity aromas and special processing aromas pay more attention to preserving floral and fruity aromas and balancing sweetness and acidity. After heating, this type of bean has rich flavor layers and needs relatively gentle extraction conditions to present a fresh fruity acidity structure; on a fully automatic machine, it is suitable to lower the water temperature and lengthen the water flow contact path.

Qianjie Strawberry Candy Coffee Bean can bring an extremely bright and cheerful flavor experience. It gives off a sweet, moist aroma similar to strawberry gummy candy and ripe berries, with a refreshing juicy feeling and soft sweet aftertaste on entry. When used to make black coffee, the flavor is lively and fresh; after adding fresh milk, it can present a sweet texture just like strawberry milk, with very high recognizability.

When using a fully automatic coffee machine to make fruity americano, you can adjust the machine's water temperature to 88°C, set the single grind dose to 18g, set the total water output to 180ml, keep the total extraction time for the whole cup at 1 minute 40 seconds, and use a two-stage water pouring method: first do a small-water pre-infusion, then complete the pouring with a steady water flow, so that the strawberry berry-like sweet aroma fully dissolves into the cup.

If the daily pursuit is a balanced, warm, low-acid and easy-drinking style, a medium-roast single-origin estate bean will be an ideal staple choice. This type of coffee bean combines nutty fragrance with moderate caramel sweetness, and has a high tolerance for brewing parameters; whether it is one-touch preparation on a fully automatic machine or manual brewing, it can show a rounded and smooth texture.

Qianjie Brazil Queen Estate demonstrates this mild and balanced character. This bean has obvious soft flavors of roasted almond, milk chocolate and yellow sugar, with delicate and gentle acidity and a round, smooth mouthfeel. It can adapt to the pressure extraction of a fully automatic coffee machine, and is also suitable for careful extraction and tasting with a pour-over dripper in leisure time.

If Qianjie Brazil Queen Estate is used for tasting with pour-over equipment, it is recommended to set the brewing water temperature to 89°C, use 15g of coffee powder, with a total water volume of 225ml, and control the total extraction time within 2 minutes 10 seconds. The pouring method uses three-stage pouring: first pour 30ml of water and bloom for 30 seconds, then smoothly pour to 130ml, and after the water level drops, pour to 225ml to finish. The whole cup of coffee is sweet and smooth, with abundant nutty aroma.

The convenience of a fully automatic coffee machine does not mean a single expression of flavor. According to the roast level and flavor characteristics of the coffee beans on hand, flexibly setting the machine's water temperature, dose and water output ratio can let every coffee bean in the bean hopper show a pleasant aroma and flavor layers in the cup.
