As the temperature drops, more and more customers order hot milk coffee at the Front Street store. The heated sweet milk and espresso blend into a cup of smooth hot latte, which is indeed very warming.
In order to prevent the hot latte from cooling down so quickly after being served, some friends will heat up the milk. At this time, it is especially important to maintain a moderate milk temperature.
—Suitable temperature for milk froth
The end point of milk foaming is based on our judgment of whether the temperature is high enough. Usually the milk temperature range for hot milk coffee produced in coffee shops will be set at 55~65℃. Since the milk foam and milk liquid produced by whipping need to be fully mixed and beaten, the milk must quickly form a vortex after air intake and enter the heating stage.
50 to 70°C is the period when the properties of milk have not changed irreversibly, so the stability is high. The milk foam in this temperature range produces the most suitable taste of hot milk coffee, and the latte art pattern is also more durable.
—When the milk foam reaches over 70℃
The temperature of the milk is too high, and we can feel that the coffee liquid and milk foam are separated when we drink it. Because the foaming time is too long, although the temperature of the milk liquid has risen, the milk foam layer that has formed countless small holes has not risen to the same temperature.
It is this temperature difference that makes us feel that the liquid is separated from the milk foam, and it is too hot so that the tongue cannot feel the dense feeling of the milk foam layer. The higher the temperature of the milk coffee, the greater the temperature difference will be.
In addition, when the milk temperature rises to above 70°C, it smells obviously milky, but when you drink it, the milk tastes very bland, with a milky smell, and the texture is rough. When it is integrated into the coffee liquid, the latte art will also easily collapse and decompose.
This is because the protein in the milk has been decomposed due to excessive temperature, and the stability of the milk foam has decreased, so it will be decomposed quickly.
How to control the whipping temperature of milk?
Beginners can first use a thermometer and their palms to feel the milk temperature.
Usually the heat source can be felt when the milk is heated to 40°C. The heating rate is determined by the temperature of the steam wand, the amount of steam and the amount of liquid in the milk tank. When your palms feel hot, it means the temperature has reached above 55°C. At this time, we remember this feeling.
If you are a milk foamer with some experience, you can directly judge the range of milk temperature by the feel. After the milk is frothed, immerse the steam wand into the milk until it reaches temperature.
In the low temperature environment of autumn and winter, the temperature of hot drinks drops faster. As for the utensils, we can preheat the cup first, or choose a material with better heat preservation, such as a ceramic cup.
FrontStreet Coffee baristas will increase the temperature of the milk foam to 65°C based on daily production parameters, which means continuous heating for 3 to 5 seconds. Balance the flavor and aroma of hot latte without affecting the taste due to being too hot.
Unlike latte, cappuccino has a thick milk foam layer of about 1.5~2cm, and everyone hopes to drink more foam. Front Street recommends controlling the temperature of Kabu's milk below 60°C so that you can drink it in large gulps without burning your mouth.
