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.
Change your mug color– This is a somewhat obscure suggestion, but a year or so ago a small study concluded that mug color could have an impact on how we taste our coffee. Specifically, using a white mug instead of a clear mug can make you perceive a coffee as more bitter and less sweet. If you regularly drink coffee out of a white mug, try changing it up and using a clear mug instead.
If you are a double espresso drinker, you are someone who believes in logic. You are an extremely practical person and are not susceptible to flights of whimsy like some of your friends.

Yuenyeung (drink) is a popular drink in Hong Kong, made of a mixture of coffee and Hong Kong-style milk tea. It was originally served at dai pai dangs (open space food vendors) and cha chaan tengs (cafe), but is now available in various types of restaurants. It can be served hot or cold. The name yuanyang, which refers to mandarin ducks, is a symbol of conjugal love in Chinese culture, as the birds usually appear in pairs and the male and female look very different. This same connotation of "pair" of two unlike items is used to name this drink.
Regular coffee (slow brewed as with a filter or cafetière) is sometimes combined with espresso to increase either the intensity of the flavour or the caffeine content. This may be called a variety of names, most commonly "red eye," "shot in the dark," and "depth charge" – though this last is a federally registered trademark of a company, Caribou Coffee, so its usage is restricted. Coffeehouse chains may have their own names, such as "turbo" at Dunkin' Donuts. A double shot of espresso in the coffee may be termed a "black eye," and a triple shot a "dead eye." "Caffè Tobio" is a version with an equal amount of coffee to espresso.
