When did you bake your coffee? What kind of treatment? What baking degree? I'm sure people who make coffee must have a way to answer these questions.

But if you are asked about the milk you use, you may not be able to answer directly. You have to look at the label on the package.

When coffee is mixed with milk, take cappuccino, for example, a whole cup may be 2/3 of milk, you have to pay as much attention to the quality of coffee and milk.

The author uses several different types of milk, but the differences between soy milk vs almond milk and full-fat vs low fat are not discussed here. Although these are also very important, this paper focuses on the treatment procedures of milk: raw milk, heating sterilization, high temperature treatment, etc. Let's learn about the differences and how they will present the flavor of cappuccino.

The main treatment of milk

Here we need to discuss some technical issues first.

The latest fresh milk that is least processed and available to people is "raw milk", which is unpasteurized and homogenized milk. A more detailed explanation is as follows:

Sterilization: raw milk is not quickly heated and cooled to kill bacteria.

Homogenization: the fat molecules of raw milk are not broken down to prevent the milk from forming a cream layer on the surface.

Because raw milk has not been sterilized at high temperature, it has always been controversial. The US Food and Drug Administration has strongly warned consumers not to drink raw milk. By contrast, many French cheeses are made from raw milk, while the British Food Standards Agency believes that as long as raw milk is properly controlled, it is suitable for non-sensitive groups to drink. Critics of raw milk point out that drinking raw milk can cause food poisoning, while supporters of raw milk say raw milk is tastier and healthier (even if health issues are not supported by research).

You can also buy milk that is pasteurized but not homogenized, and, less commonly, homogenized milk that is not pasteurized. However, generally available milk is pasteurized and homogenized.

There are many forms of high temperature sterilization, of which the two most common are "high temperature short time sterilization HTST" and "ultra high temperature instant sterilization UHT". According to the International Dairy Association, HTST milk will be heated at 70-75 oC for 15 seconds and still need to be refrigerated; ultra-high temperature instant sterilization UHT milk will be heated at 120-130 oC for 2 seconds.

(readers add that there are two other treatments: low temperature long time sterilization (LTLT): 62-65 oC, heated for 30 minutes.

Ultra-high temperature sterilization (UHT-sterilization) can also be called preserved milk: 135-150 oC, heated for 2-5 seconds. )

Experiment with different milk

First of all, each kind of coffee is different, and so is every kind of milk. Different coffee varieties, farms and coffee trees will produce different flavor coffee; different cattle breeds, cattle grazing management, feed and so on will produce different milk composition and flavor. This is the charm of the third wave of coffee. We will pay attention to the differences in the flavor of coffee cups, and we also know that different coffees do have very different flavors.

Therefore, when we experiment with different kinds of milk, we must first understand that the results cannot be generalized. If we use different brands of milk with coffee from different places, the results will be different. After all, they all belong to agricultural products.

However, actually trying this milk can help us gain a deeper understanding of the main differences. The author collected raw milk, inhomogeneous but pasteurized milk, HTST and UHT milk, and tasted them all for one round, including iced milk, milk foam, cappuccino and so on.

Espresso is Ijen from East Java, Indonesia. The coffee flavor is described as roasted peanuts, strawberry jam-like acidity and a long finish.

Raw milk

The author obtained milk from a local farm in North Bandung Dago, Indonesia. While observing how dairy farmer Mark milked, Mark told the author some details about cow breeding. If the analogy of direct trade in coffee is "from seed to cup", milk is "from cow to cup".

When the author tastes cold milk, he can drink sweetness and thick taste. When the milk is steamed, the sweetness will decrease, and the creamy taste and texture will be more prominent. In a cappuccino, there will be a smooth taste, accompanied by caramel flavor and a slight banana flavor.

High temperature sterilization but not homogenization

Remember that there are many ways to sterilize milk at high temperature. Milk heated by 63oC for 15 seconds is used here. Drink from the cold, you can drink a very sweet but thinner taste; steaming will increase the slightly round taste, while the sweetness will remain the same as when it is cold. However, when a cappuccino is made, it will enhance the bitterness of the coffee and give the whole feeling of over-caramelization.

So the author conducted a second experiment: using beans with roasted degree of hand-brewed coffee to boil and concentrate, and try to drink only concentrated and add two cups of milk flavor. When drinking espresso, it tastes sour; the addition of milk amplifies the fruit flavor and increases the overall sweetness of the coffee. For the author, this milk is perfect for making fruit-flavored cappuccinos (shallow baked beans).

HTST high temperature short time method

This kind of milk is the easiest to obtain and has a reasonable shelf life to increase the convenience of store use.

When cold, the author drinks with creamy taste, medium sweetness, and medium-weak texture. The sweetness of steamed milk is increased, and then the sweetness is increased after making cappuccino.

However, the milk was used in the author's store for nearly a year, so baristas have become familiar with how to match the flavor of coffee to use the milk.

UHT ultra-high temperature method

For the author, the milk has a long and creamy finish, but it is so sweet that it tastes like a can. The steamed surface is smooth and creamy, but there are no foam. After making cappuccino, there is still no milk foam, and the flavor becomes bitter and insipid.

No matter what kind of milk we use, trying different kinds of milk will help to find out which milk is most suitable for your coffee, and in addition to coffee, we need to know more about the effects of milk on your other drinks. These practices help to detect different degrees of sweetness and caramel cream, just as testing different cups of coffee can improve your taste. So try adding different milk to different coffees, and then compare the flavor differences.
