When it comes to choosing Italian coffee beans, FrontStreet Coffee focuses first on the freshness of the beans, and then on to the flavor, mellowness, balance of sourness and bitterness, etc. The espresso currently used by FrontStreet Coffee is Front Street Sunflower Warm Italian Blend coffee beans roasted in-house in order to increase the richness and harmony of the coffee taste. What are blended coffee beans? Next, let’s talk about the four Front Street espresso blended coffee beans currently on the shelves and see what the differences are between the blended coffee beans.

Before choosing any Italian blend coffee beans, how do we judge the freshness of the coffee 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 addition, good coffee packaging bags usually have a "one-way exhaust valve" (a small button-shaped hole on the top of the coffee bag) design to allow the coffee beans to discharge naturally occurring carbon dioxide.

Aim the one-way exhaust valve at your nose, gently squeeze the coffee bean bag, and smell the squeezed out gas. If it has a charming and fragrant coffee aroma, the freshness is not a problem. On the contrary, if the smell is not strong enough, or even smells of stinky oil, it means that the bag of coffee has already deteriorated and stale, and you should avoid buying it. Every package of coffee beans sold by FrontStreet Coffee is packaged with a one-way exhaust valve, ensuring that each package of coffee beans reaches the hands of enthusiasts in the freshest state. The reason why Front Street places so much emphasis on fresh roasting is because as time goes by, the coffee will basically lose its aroma after it has been roasted for more than 50 days. Some people may ask, is the fresher the coffee, the better? No, the aroma is not very stable in the first two days after it is roasted.

For espresso beans, due to medium-to-dark roasting, a large amount of carbon dioxide is retained in the body after the beans are roasted. Front Street recommends that the original packaging be kept unopened in a cool, moisture-proof place, and the coffee beans should be allowed to grow in a static state (the process of coffee beans releasing carbon dioxide) for 7 days from the roasting date before brewing.  
 
What are coffee bean blends?
Blend coffee, also known as blended coffee and espresso beans, is to mix various single-origin coffee beans together to fully bring out the advantages of various single-origin coffee beans. The blended beans are mixed from coffee beans from different origins to create a more balanced taste. For example, if a kind of coffee bean is smooth but lacks aroma, you can add another bean with rich aroma. The advantages of individual coffee beans can be used to complement each other and complement or enhance the taste, thereby creating a new and richer taste of coffee. Sometimes the beans are mixed first and then roasted, which is called raw blending; sometimes the coffee beans are roasted and then mixed, which is called cooked blending.

Whether it is pre-mixed green beans, or roasted individually and then mixed. Both methods are acceptable depending on the characteristics of the coffee in the recipe. Post-roast blending provides each bean with varying degrees of roasting so that each ingredient brings out the best in it.

 

FrontStreet Coffee would like to remind you that before blending beans, you must first know the flavors of different varieties of coffee in the world. Beans have different characteristics depending on the place of origin. This requires roasters to understand the characteristics of coffee beans from multiple production areas to adjust the roasting curve. Different coffee beans have different personalities due to different varieties and origins. There are subtle differences in sour, bitter, sweet, aroma, mellow and other flavors. Single-origin coffee beans often focus on showing the unique characteristics of a certain type of coffee.

Mixing different coffee beans mainly serves the following purposes:
1. Stable flavor
Since coffee beans are a type of crop, even the same kind of coffee beans will have different flavors from year to year, so blending several coffee beans together solves this problem and keeps the taste basically the same every year.


2. Balance the taste
Since an espresso machine has the characteristic of amplifying the most prominent flavor characteristics of the coffee beans, we almost never use a single variety of coffee to make Espresso. Otherwise, if the coffee beans are bitter, the Espresso will be extremely bitter, and if it is too sour, it will be very sour. So we need to balance the flavors through blending.

Below, the Sunflower Warm Italian blend currently used in FrontStreet Coffee stores will be used as the protagonist to demonstrate how to extract a delicious cup of espresso base.

 

Step 1. Clean the powder bowl


Before extracting espresso, you need to remove the coffee handle and clean the coffee powder bowl with a special rag to ensure that the powder bowl is clean and free of water stains.

Step 2: Grind the coffee powder and collect it

Turn on the grinder and start grinding the coffee beans. Before picking up the coffee powder, you need to place the handle on the electronic scale and clear it. Then, after picking up the coffee powder, put the electronic scale on it to ensure that the weight of the coffee powder is consistent every time. When picking up the coffee powder, pay attention to where the coffee powder falls on the handle and ensure that the coffee powder falls evenly on all areas of the handle.

Step three: cloth powder
After receiving the coffee powder, use your fingers or a powder distributor to spread the powder. The purpose is to ensure that the coffee powder is evenly distributed and avoid density inconsistencies when filling later.

Step 4. Filling

After spreading the powder, fill it. When filling, the direction should be vertical to the powder bowl. The strength should be moderate. It should not be too light or too heavy. Too light will make the coffee powder cake loose. Too heavy will make the coffee powder cake too compact and dense, making it difficult for water flow to pass through the coffee powder cake, resulting in over-extraction.

Step 5. Buckle the handle and extract espresso at the same time    
  
Gently fasten the handle to the coffee machine to avoid bumping the handle into the coffee machine. Excessive bumps will cause cracks in the coffee powder in the handle, leading to channeling, under-extraction and uneven extraction. After fastening the handle, immediately turn on the extraction switch and start extracting espresso. When the extraction starts, use an electronic scale to weigh the espresso liquid, and always pay attention to the coffee extraction time and the color status of the coffee liquid.
