Ristretto: (Ristretto in Italian means "restricted, shrunk or short”) It is the richest and most concentrated espresso drink where less water but the same amount of coffee is used to make the beverage and creates a less bitter espresso. The extraction time is shortened producing as little as 3 oz of liquid per serving. Pure and intense espresso served in a demitasse cup.
Coffee’s a diuretic. This means drinking coffee will make you urinate more frequently than if you didn’t drink coffee. This is a good thing in most cases because it keeps your system cleansed. The human body often flushes out harmful bacteria and viruses this way, and drinking coffee enhances this natural process. Through this, black coffee drinkers become sick far less often.
Caffeine might also offer some calorie-burning benefits that help your weight-loss efforts, but it's too early to say for sure. One laboratory study, published in Food & Function in 2012, found that caffeine boosted thermogenesis — a phenomenon that helps you burn more calories. And a study published in the European Journal of Clinical Nutrition in 2009 found that caffeine also boosted thermogenesis in people, although this study was small and included only seven test subjects.

In addition to the caffeine, chlorogenic acid in a cup of black coffee will help the fat burning process. Those substances will activate the enzyme in the digestion system such as lipase which is able to break down fat. In the other word, lipase will helps the process to burn fat, since fat need to be broken down before it is perfectly burned. The normal process might take about 20 minutes to burn fat. However, the caffeine and chlorogenic acid in a cup of black coffee will make the process efficiently faster.
The two most Kiwi coffees available are the long black and the flat white – as both originated in New Zealand and Australia. For a flat white, the steamed milk from the bottom of the jug (which is usually not so frothy, but rather creamy) is poured over a shot of espresso. It is now popular among mums and dads at school fetes who are desperately trying to stay awake.
The kinds of coffee are technically divided into three, according to where they came from and the variety of the beans used to make the brew. The basic kinds of coffee are: one-origin, one-estate and blends. When coffee originates from one land and all the beans have a common flavour, this is called one-estate coffee. The one-origin kinds of coffee are made from a mixture of beans harvested in a the region but from different estates. Blend coffee types are the most popular kind. Different kinds of beans from different estates and regions are mixed together to obtain a unique taste. It’s safe to say that most of the coffee varieties we know and love are blends.

Cold brew coffee originated in Japan, where it has been a traditional method of coffee brewing for centuries.[11] 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),[12] refers to a process in which water is dripped through coffee grounds at room temperature over the course of many hours.[13] Cold brew can be infused with nitrogen to make nitro cold brew coffee.

Caffeine, the most widely consumed psychoactive substance in the world, is the best known ingredient of coffee. Its beneficial effects on the human body has been researched quite well, but coffee as a whole is a complex beverage with a thousand different substances. Some studies argue that decaf and caffeinated coffee may have the same health effects and suggest that it’s not the caffeine that is responsible for most of coffee's health benefits.
Drinking black coffee daily helps to reduce the risk of diabetes which in later age can lead to organ damage and heart diseases. It was seen people who drank 2 or less cups of coffee had increased risk of diabetes. Coffee helps in controlling diabetes by increasing insulin production. Both caffeinated and decaffeinated coffee help in prevention of diabetes.
