Coffee might be brewed in numerous ways, although four main methods exist. These methods differ based on how the coffee receives water. After coffee is brewed, the beverage is best if consumed quickly. If the coffee turns cold, it takes on a “muddy” flavor and loses its original taste and aroma. If kept free of oxygen, however, coffee retains its original flavor, and sealed coffee can be purchased in America and Europe. In Japan, canned coffee is growing in popularity. One can also find cold coffee beverages in a grocery store’s refrigerated section.

Until the 1930s, boiling coffee was a popular method, and it is still employed today in the Middle East. On method of boiling coffee is “cowboy coffee,” where coffee grounds are placed in a pot of water. As the grounds settle, the resulting beverage is poured from the pot. Often, the grounds are filtered before pouring. As the name suggests, this method was popular with cowboys and herders around campfires. However, some people simply prefer this method, and it is still used today, notably in Finland and Sweden.

Steeping is another coffee brewing method. A French press is a tall cylinder containing a plunger and a mesh filter. To brew coffee, coffee grounds are placed into the cylinder; then, boiling water is introduced. For about seven minutes, the concoction is left in the cylinder, after which the plunger is pushed down, which brings the drink above the filter. In Malaysia, coffee is steeped using a sock. This sock is a muslin bag that acts as the device’s filter. Coffee is placed in the sock and then steeped in boiling water. In this method, the coffee sock is sometimes reusable, and the brew is typically strong.

In drip coffee making, which is the most popular method used today, coffee grounds are placed in a filter, and hot water pours over the coffee. Generally, coffee filtration uses modern coffee brewing machines, and this technique is mostly found in America. Containing more caffeine than espresso, drip coffee’s strength depends on the ratio of water to coffee grounds. A different filtration method is filter coffee found in India. The machine, comprised of stainless steel, has two cylinders, one on top of the other. The top cylinder contains tiny holes, where fine coffee grinds are introduced. Here, hot water is poured over a disc. Unlike American drip coffee making, coffee is not immediately produced and dripped. The device retains water longer, producing a much stronger brew.

The final coffee making method is espresso. Here, hot water is forced under the pressure of up to 15 bars, through a puck, or tight matrix, containing fine coffee grounds. Served in small cups, one often adds sugar to the concoction. Commonly consumed at cafes and vendors, the drink is also popularly drunk after large meals. The base for many other coffee beverages, espresso is highly concentrated and potent. Espresso has a unique flavor because the drink boasts crema, or foam, which floats on top of the drink.
