White Rum

In the making of Rum, the produce of the fermentation and distillation process of molasses is a transparent spirit, which is then aged in vats or barrels and the end result of the ageing is Rum.

There are no legal categorisatoin of Rums and it's just a matter of practice that dark rum is used in cooking or is drunk straight or with a Cola , white rums are mostly used in cocktails.

Bourbon Whiskey

American's don't need to be lectured on Bourbon, but still, let's put it in record like all other spirits. A Bourbon in American spirit is a barrel-aged distilled liquor made primarily from corn. The name might have been derived from the French Bourbon dynasty, or from Bourbon County in Kentucky, or Bourbon Street in New Orleans, both named after the French Dynasty.

Technically, most whiskey made in America are legally classified as Bourbon, although Bourbon is in spirit a Southern Whiskey with special connection to Kentucky. Note than although Tennessee Whiskey is classified as Bourbon, Tennessee distilleries do not prefer their whiskey to be unique and referred to as Tennessee Whiskey only.

Distilling came to Kentucky in the late 18rth Century with the Scots, Scot-Irish and other settlers including English, Welsh, German and French, and they brought with them their distilling techniques and ageing processes in charred oak barrels. The charring is what gives the Bourbon the brownish colour and distinctive taste.

To be a legal Bourbon, a whiskey has to meet the following criteria

Produced in the United States and Territories (Puerto Rico) and the District of Columbia
Made from a grain mixture that is at least 51% corn
Aged in new, charred oak containers
Distilled to no more than 160 (U.S.) proof (80% alcohol by volume)
Entered into the container for aging at no more than 125 proof (62.5% alcohol by volume)
Bottled (like other whiskeys) at 80 proof or more (40% alcohol by volume)

Lime Juice being rich in Vitamin C is an excellent remedy for sore throat and aids in digestion and controls blood sugar, and also promoted weight loss.

The difference between Lime Juice and Lemon Juice is that although the sweet and sour Lemon and the bitter and sour Lime are two different fruits, they have similar properties and tastes similar too, the Lime, unlike the sweet and large Lemon, is used raw and is usually plucked green and has more bitterness and sourness in it's taste, and is grown better in tropical and sub-tropical climates.
In drink mixing, fresh lemon juice brings a tangy zing to so many classic drinks and in fact, it's the most used ingredient in drink mixing other than the liquors of course.

Milk
