Depending on how you create it though, this beverage can either taste truly sublime or be downright undrinkable. More confounding is that if you're not careful the results can potentially vary wildly, even when you use the same coffee beans from an identical bag roasted within the same batch and at the same time. This is why consistency is important in each step.
Espresso is brewed by using an espresso machine to force a small amount of nearly boiling water and steam – about 86 to 95 °C (187 to 203 °F) – under pressure through finely ground and compacted coffee. The espresso machine was patented in 1901 from an earlier 1884 machine, and developed in Italy; with the invention of the Gaggia machine, espresso spread in popularity to the UK in the 1950s where it was more often drunk with milk as cappuccino due to the influence of the British milk bars, then America in the 1980s where again it was mainly drunk with milk, and then via coffeehouse chains it spread worldwide. Espresso is generally denser than coffee brewed by other methods, having a higher concentration of suspended and dissolved solids; it generally has a creamy foam on top termed "crema". Espresso is the base for a number of other coffee drinks, such as latte, cappuccino, macchiato, mocha, and Americano.
Cold brew coffee originated in Japan, where it has been a traditional method of coffee brewing for centuries. Slow-drip cold brew, also known as Kyoto-style, or as Dutch coffee in East Asia (after the name of coffee essences brought to Asia by the Dutch), refers to a process in which water is dripped through coffee grounds at room temperature over the course of many hours. Cold brew can be infused with nitrogen to make nitro cold brew coffee.

A few months ago I decided to start drinking coffee black cold turkey. I used to add two tablespoons of nondairy creamer and sometimes even four packets of Splenda. My wife who enjoys coffee with a little creamer (and that’s all) thought my coffee tasted like candy. After realizing my coffee was more like a meal, I decided to just stop altogether and drink it black.
Instant coffee is great when you need a pick-me-up but don't have a coffee maker. Unlike ground coffee, instant coffee granules are made from dehydrated brewed coffee. Although this means you can't make the actual granules at home, instant coffee is still an easy, tasty way to get your caffeine fix! It's particularly great when iced, and you could get creative by adding spices, whipping up a fancy latte, or making a frosty coffee shake.
Coffee contains ingredients that both lower your blood sugar and increase your resting metabolic rate, reducing your risk for diabetes. Additionally, nutrients in coffee help your body use insulin, a hormone necessary to use and store sugar you get from food. Substantial coffee drinkers, of either regular or decaffeinated coffee, could be half as likely to develop diabetes than those who drink little to no coffee. The association between coffee intake and diabetes proposes that each cup of coffee you drink per day, could result in a 7 percent reduction in your risk for developing diabetes.
The National Cancer Institute has reported that men who drink coffee regularly are less likely to develop prostate cancer. A 60 percent reduction in the risk of developing lethal prostate cancer was found in men who drank 6 or more cups of coffee per day. Even 1 to 3 cups of coffee reduced the risk. Four or more cups of coffee per day have also been shown to reduce the incidence of colon cancer. Furthermore, researchers discovered that people who drink coffee are 50 percent less likely to develop liver cancer than their non-drinking counterparts. Additional studies have linked coffee consumption to lower rates of breast and rectal cancer.
According to professor Achmad Subagio of the Research Institute of the University of Jember, drinking black coffee twice a day prevents the risk of Parkinson's disease because caffeine elevates the dopamine levels in the body. Parkinson's disease affects the brain's nerve cells that produce dopamine, a neurotransmitter responsible for transmitting signals between the nerve cells of the brain.
Women who drank more than 4 cups of coffee per day, had a 20 per cent lower risk of becoming depressed. The reason being the caffeine, a natural stimulant which stimulates the central nervous system and increases dopamine levels  . An increase in dopamine levels removes the symptoms of depression and anxiety  . And due to this people are less likely to commit suicide .
Lower Risk of Multiple Sclerosis. Recent research showed that at least 4 cups of coffee a day may help protect against the development and reoccurrence of MS.

Both caffeinated and decaffeinated coffee help in prevention of diabetes.
