One of the highly popular beverages of the world is coffee. A sip of freshly brewed coffee can be indeed a vitalizing start to a day of drudgery. The variety of ways in which coffee is prepared throughout the world is just remarkable. Some of the well-known forms of the coffee beverages are Caffe espresso, Irish coffee, Red eye, Black eye, Dead eye, Americano/Long black, Cafe mocha, Cafe au lait/Cafe con leche, Cortado, Ca phe sua da, Cappuccino, Turkish coffee, Latte/Flat white, Indian filter coffee, Macchiato (espresso, latte), Greek frappe coffee, Iced coffee and Instant coffee.
One of the exceptional coffee beverage preparations is the Irish coffee or Caife Gaelach, the inception of which dates back to the 1940s. Created in Ireland as the name suggests as a drink to keep the trans-Atlantic travelers warm, the Irish coffee is a desirable concoction of sugar, hot coffee, Irish whiskey topped with whipped cream that floats in the coffee. 
How exactly do you prepare this amazing beverage? Well, first you go about preparing the black coffee in the routine manner. Once this is done comes the part of adding the Irish whiskey (2 parts) and sugar (a teaspoon or more as per will) to the hot coffee (4 parts). Keep on stove but take care the mixture does not boil. The addition of sugar is important because it is due to the sugar that the whipped cream added later will float on the coffee rather than drowning into the mixture. Once the sugar dissolves pull off the stove, pour into a special Irish coffee mug and add the cream in manner that gives the cream an appearance of a peak or head.
Over the years, many regions of the world have come up with their variations to the renowned Irish coffee. The variants are as follows:
1.) Dutch coffee (no cream topping but contains advocaat in addition to Irish whiskey)
2.) You will find the famous vodka substituting the Irish whiskey in the Russian coffee.
3.) In the Jamaican coffee, dark rum or Tia Maria is used.
4.) The Spanish coffee consists of sherry in place of Irish whiskey.
5.) Scotch coffee (replacement of Irish whiskey with Scotch whiskey)
6.) The French have theirs with brandy or Cognac instead of Irish whiskey.
7.) Kentucky coffee uses the Bourbon whiskey.
8.) Baileys coffee, which replaces the usual cream with the Baileys Irish cream.
