Don’t think that latte is just coffee beans + milk. You may not know the details.

Of all the seasons, autumn is probably the least “useful”.

So " hot latte"

Speaking of latte, everyone should be familiar with it. In almost all Italian coffee shops, "latte" is the most ordered and classic milk coffee. However, the difference between latte and latte is very large. In addition, there are no clear standard restrictions on the production of Italian coffee, so we can almost apply a classic line: "There are a hundred kinds of lattes for a hundred coffee shops."

We must first understand some basic knowledge about latte:

1. Latte refers to the espresso liquid (called espresso in English) + whole milk + milk foam whipped by high-temperature steam made by high-pressure Italian coffee machine. The coffee beans used to make espresso liquid are mainly medium-deep and deep-roasted blended coffee beans.

Blended coffee beans: Made from coffee beans from different regions and varieties. Most coffee shops use commercial-grade Robusta coffee beans, which are cheap. However, in recent years, many coffee shops have become more concerned about the quality of coffee beans and have begun to use more expensive Arabica coffee beans, but they are still mainly blended. There are also espresso liquids made from single-variety coffee beans, which we call SOE, which is more expensive.

2. The milk used to make latte must be whole milk in order to more easily whip up dense milk foam. In the past, coffee shops mostly chose whole milk at room temperature, which has lower costs and longer storage times. However, in recent years, due to industry competition and people's increasing attention to milk quality, fresh milk (of course, whole milk), which is more expensive and needs to be refrigerated and has a shorter shelf life, has increasingly replaced room temperature milk in commercial coffee shops.

Whole milk: It is milk that has not been skimmed and has a fat content of about 3%.

Fresh milk: It does not refer to milk that has just been squeezed out and drunk directly, but milk that has been processed by pasteurization. It is sterilized at a low temperature of about 72℃-85℃, which can kill harmful bacteria in the milk while maintaining the beneficial bacteria in the milk, preserving the nutrients of the milk to the greatest extent, and well preserving the nutrients and pure taste. However, the shelf life of low-temperature sterilized milk is short, generally not more than 10 days, and it must be refrigerated. (It is the quality first choice of most coffee shops now.)

Room temperature milk: refers to milk that is sterilized at 138℃-142℃ to instantly heat up, thereby killing all harmful bacteria in the milk. Such milk can be kept for 1 to 8 months in a sterile state and does not need to be refrigerated. However, due to the high temperature, the nutritional active substances in the milk, such as protein, vitamins, calcium and other elements, will suffer a great loss. (The purchase cost and storage cost are relatively low, and some coffee shops will also choose it.)
