By splitting the extracted espresso into 2 to 3 portions, and then making different types of coffee respectively, the final combination is produced. This is a very popular form of production in coffee shops today - Coffee combo.

Because you can taste different "dishes" made from one bean at the same time, and the cup size is small and does not occupy your stomach, Combo has been sought after by many people. For this reason, more and more coffee shops are beginning to produce Combo(Except Front Street)。
Although it seems so simple, many friends found that after actually making it, there was always a cup of coffee that tasted unsatisfactory. It's either too bitter, or it tastes bland, and the aroma isn't very prominent. So some friends will ask Front Street customer service when buying beans on Taobao online, is it useless to buy beans?

To be fair, in fact, all coffee beans can be used to make Combo, because Combo, as mentioned in the front street, just splits one espresso into two or three parts, and then makes different types of coffee. In our daily life, most of the Italian coffee is made in this way, so Front Street said that all coffee beans can be used to make Combo.
But if you have certain requirements for your Combo, such as it having some special aroma and impressive memory points, then there are certain requirements for the selection of coffee beans. For example, it must have sufficient aroma and sufficient taste, which are also the characteristics of coffee beans used in most coffee shops today when making Combo. So today Front Street will share what kind of coffee beans are suitable for making Combo!

1. The degree of baking will not be too extreme
If we want to make a Combo with a rich aroma and outstanding flavor, then it is best not to choose very dark roasted coffee beans for production. Because roasting too dark will add a lot of burnt aroma to the coffee and the taste will be thicker, which will cover up the flavor of the coffee and prevent us from drinking the flavor characteristics of the coffee itself.(It’s not that dark roasted beans are bad, it’s just not suitable for this purpose)

图片

Of course, coffee beans that are too lightly roasted are not suitable either! Although lighter roasting will not have any burnt aroma to cover up the flavor, because there is not enough caramelization reaction, the coffee will not be as sweet and taste more sour. And because the flavor and taste are relatively weak, it will be easily covered up by the taste of milk, and the milk coffee will be tasteless.

图片

Therefore, when we make Combo, it is best to use some medium-light and medium-roasted coffee beans. Because these roasted beans retain enough flavor, and because the caramelization reaction proceeds just right, they not only bring a high enough sweetness to the coffee, but also have the ability to compete with the taste of milk.

2. Deep fermentation
Then if we want the coffee to have a prominent enough flavor, we can also limit the processing method. For example, choose some coffee beans that use a darker fermentation process to make combo. For example, sun exposure,Anaerobic, honey-processed beans.

In previous tweets introducing processing methods, Front Street mentioned that different processing methods will cause different degrees of fermentation of coffee beans. The deeper the fermentation, the richer and more prominent the aroma of the coffee beans will be. And sunlight, anaerobic,honey treatmentThese methods will allow the coffee beans to ferment deeply enough to develop a very rich flavor.
So if we want to make a combo with outstanding flavor performance, coffee beans processed in these ways will be a good choice.

What are the beans that meet the above two points?
There are still a lot of coffee beans that meet the above two points! For example, in the bean list of Front Street, more than half of the coffee beans meet these two conditions: just the right degree of roasting, and rich and outstanding aroma. Among them, there are several types of coffee beans that many coffee shops like to use in Combo. Their aroma is very rich and very special. You can refer to it~
The first one isFront Street Esai Alo, the coffee made with it has the flavor of mango, pineapple, citrus, and magnolia; the second one is Front StreetDivide Manor·Xijiao, its flavor expression includes grape, passion fruit, floral aroma, and fruit wine; the third one is the Front Street Gesha Blend·Strawberry Candy that is often shared on Front Street. The coffee made with it will have outstanding flavors of strawberry fudge, white floral aroma, and citrus ~

Points to note when making combos
After we get the right coffee beans, we need to start making coffee. Regarding Combo, there are many things we need to pay attention to when making it.
①Use of powder amount:Since espresso needs to be split into multiple portions to make different coffees, unless you usually use a larger amount of powder, it is best to increase the amount of powder used appropriately. Because we generally follow 1:2(left and right)ratio for extraction. If the amount of powder used is relatively small, then the average amount of coffee liquid will not be too much, and the cup size will be smaller.(This is something that coffee shops need to pay attention to. Home users can do whatever they want~)

②Concentrated extraction:After debugging the concentrated extraction parameters every morning, the coffee shop will also make a special cup of latte to verify whether this cup of concentrated coffee can be used to make a latte. Why? Because delicious espresso is not necessarily suitable for making latte coffee!

图片

When the flavor of espresso is not strong enough, or the acidity is too prominent, the milk coffee produced will not taste so good. Maybe it’s because there’s no coffee flavor, or maybe it’s just a bit abrupt when you drink it. For coffee like latte, which requires the addition of a large amount of milk, the concentrated base needs to have a certain bitterness to produce a cup of rich-tasting milk, while black coffee such as Americano does not need to be. Therefore, when making morning adjustments, we also need to make an additional cup of latte to test whether this concentrate is suitable for making latte.(one of the reasons)。
Therefore, when making Combo, many coffee shops will specifically add more concentrate to the portion used for latte making. This can effectively enhance the bitterness of the coffee and increase the balance of the taste, thereby creating a latte with outstanding flavor.

③The ratio between coffee and materials:The last thing is the proportion. Since the coffee beans we use to make Combo are generally lighter than those used for regular Italian, we'd better adjust the proportion appropriately. For example, the ratio of Combo American coffee and water, and the ratio of Combo Latte coffee and milk can be appropriately increased.

图片

Take Front Street as an example. When Front Street uses a medium-dark roasted Front Street classic blend in the bean list to make a regular latte, the ratio of coffee to milk is 1:5, that is, 40ml of espresso will be paired with 200ml of milk.
And if you use the medium-light roasted Front Street Dividing Line·Xizhao in the bean list to make the latte in the Combo, the ratio of coffee to milk will be 1:4~4.5. The reason is the same as mentioned before, because the roasting is not that deep, so the flavor intensity is not that high, so naturally you cannot add too much water or milk to dilute the taste of the coffee.

So, the above are some of the production matters and coffee bean selection when we make Combo. Of course, Front Street here is just a reference for everyone. In actual operation, it still needs to be adjusted according to the specific situation.
