Does the mocha pot need a menu valve or a dual valve? What is the difference between a single-valve mocha pot and a double-valve mocha pot?

In order to be able to make various coffees at home, many friends plan to buy a coffee appliance. The mocha pot has become the preferred choice when buying equipment because of its cheap price, portability and simplicity.

"Is a menu valve better or a dual valve better? "This is a question that many friends struggle with when buying a mocha pot. In addition to different brands to choose from, today's mocha pots also have different valve numbers. Single valve, double valve, or even triple valve, this makes many friends who have just started confused. Even if you search for which is better on a certain website, you will always get ambiguous answers. Therefore, friends often ask Qianjie such questions when buying coffee beans at Qianjie stores. Single valve or double valve is a question worth thinking about! So today, Qianjie will come to share with you what the difference is between a single-valve mocha pot and a dual-valve mocha pot, and then for new friends, how should we buy it?

What is the difference between a single valve and a double valve mocha pot? From a structural point of view, there is not much difference between single-valve and dual-valve mocha pots. They all consist of a sink, a powder trough, and an upper pot for holding coffee liquor. The generation of water vapor is accelerated by heating the hot water in the sink of the lower pot, and then continuously accumulating to obtain pressure that can push the hot water to move upward to extract coffee. Finally, the hot water will dissolve the soluble matter in the coffee and turn into coffee liquid. The liquid outlet of the upper pot seeps out, which is the entire extraction process of the mocha pot. Both single and double valve mocha pots are the same.

However, the difference from the single valve is that the dual-valve mocha pot has an extra valve. There will be a valve that looks like a switch above the lower pot of the mocha pot. This is an exhaust valve that every mocha pot is equipped with. The function is that when the pressure in the mocha pot builds up too much, you can pass through this valve. To discharge water vapor in time to avoid the consequences of frying the pot. The dual-valve mocha pot will have an extra valve on top of this, which is called a booster valve. As the name suggests, it is used to increase the pressure during extraction.

If you have searched for posts related to single and double valve mocha pots, Qianjie believes that you should have seen a lot of comments similar to the online conversation between two fans in the comment area of a certain post, such as what: A dual-valve mocha pot will make bitter coffee easier than a single-valve mocha pot, and the coffee made by a single-valve mocha pot is not as strong as a double-valve... Then none of this is actually wrong! Under the same parameters, the coffee made by a dual-valve mocha pot will indeed be stronger than that made by a single-valve mocha pot, and then it will indeed be easier to make a pot of bitter coffee. The reason is that the dual-valve mocha pot has an extra booster valve.

Qianjie mentioned earlier that the role of the booster valve is to increase the pressure of the coffee during extraction. When the pressure involved in the extraction is higher, the extraction efficiency will be higher and the flavor of the coffee will be stronger, because more substances will be dissolved. But precisely because more substances are dissolved, it is easier for us to dissolve a large amount of negative substances such as bitter, miscellaneous, and astringent during extraction, resulting in an obvious unflattering experience in coffee. But what we need to know is that although it is easy to overdraw, this is only relatively speaking, and the fault tolerance rate of the mocha pot is still relatively high! We only need to control the parameters and methods of use, so the coffee produced will not be prone to over-extraction.

So back to the topic, should the mocha pot have a single valve or a dual valve?

Do you want a single valve or a dual valve for a mocha pot? It is said that buy the new and not the old, and this saying has some truth. Compared with single-valve mocha pots, the Front Street Conference recommends dual-valve mocha pots. Because it can make stronger black coffee, in addition to meeting our daily black coffee needs, it can also be used to make milk coffee. Because the concentration of the coffee base is higher, the milk coffee made with it will have a more fragrant performance.

But this does not mean that the single-valve mocha pot is not good. The single-valve mocha pot also has its own advantages! If you are a friend who doesn't like it and believes that you won't make milk coffee in the future, then the single-valve mocha pot will be more suitable for you. Because its size will be relatively smaller, and the price will be reduced due to the introduction of the dual-valve mocha pot, the cost performance will be relatively higher. Of course, the espresso brewed in a single-valve mocha pot can also make a cup of fragrant milk coffee, but compared with the coffee brewed in a dual-valve mocha pot, its concentration will be less high and the taste will be slightly weaker.

All in all, if you have a need for milk coffee, or if you are not just satisfied with black coffee, Qianjie will recommend you to buy a dual-valve mocha pot; and if you only want to drink a cup of pure black coffee, there is not much demand for fancy coffees such as milk coffee and special flavors, so the single-valve mocha pot will be more cost-effective. When you buy the mocha pot, if you don't know how to use it and how to make delicious coffee, you can find out by searching in the articles shared by Qianjie in the past. The last thing to note is that the Taobao Tmall store on Qianjie only sells coffee beans, not mocha pots...
