Best Portable Espresso Machine: What Is A Portable Coffee Maker?
A portable coffee maker is a device that allows you to make your own hot beverages from any type of liquid or solid material. There are many types of portable coffee makers available today. Some of them include the following:
The most common type of portable coffee maker is the Keurig® K-Cup™, which was introduced in 2007. It uses a single filter to brew coffee. You simply place the filter into the brewer and press the button. The brewer then automatically begins brewing your beverage.
Another popular type of portable coffee maker is the Folgers® AeroPress®, which was introduced in 2011. It uses a manual pressurized pump to brew coffee. The brewer contains two chambers; one containing hot water and the other containing cold water. To make your drink, you simply pour the contents of the chamber with cold water into the chamber with hot water.
Then, you place a solid stick of coffee in the middle and press down with the manual pump for about twenty seconds.
The third type of portable coffee maker is the Moka Express®, which was also introduced in 2011. It works similarly to the traditional stovetop espresso maker. You simply fill the bottom chamber with water, making sure it does not exceed the max line. Then, you fill the filter with finely ground coffee, place it into the chamber, and twist on the top piece.
You place the coffee maker on the stove and turn on high heat. As the water boils, it creates a vacuum which forces the water up through the filter and into the top chamber, which contains the coffee grounds. You can then place this in the refrigerator to cool for a few minutes before serving.
Now that you are familiar with some of your options, let’s take a closer look at some of these models.
