Bacardi 151 Proof Rum

Overproof Rums are Rums with a much higher alcohol concentration which is usually greater than 57.5% but although 151 proof means 75.5% ABV, most Rums with 57.5% Alcohol are labelled as 151.

Overproof Rums are highly inflammable and are usually used in cocktails as a top layer meant to be ignited and burst into flames, rendering a charred flavour to the drink while arousing awe and interest by quite a fire show.

Overproof Rums are not meant to be drank neat or even as a base spirit, the alcohol concentration is too high, but it can add special character to mixed drinks.

Bacardi 151 was a famous overproof Rum and although it has been discontinued in 2016, there are other pretty famous brands like Lemon Hart 151, Hamilton 151, Wray and Nephew White Overproof Rum and Pusser’s Gunpowder Proof.

Note: Gunpowder Proofing a Navy Rum was an old concept, where Rum poured over Gun powder would not wet the gun powder and when lit, the gun powder will catch fire once the alcohol has burnt.

Navy rum was originally a blend mixed from rums produced in the West Indies. It was initially supplied at a strength of 100 degrees (UK) proof, 57% alcohol by volume (ABV), as that was the only strength that could be tested (by the gunpowder test) before the invention of the hydrometer. The term "Navy strength" is used in modern Britain to specify spirits bottled at 57% ABV. - Wikepedia

Gin

Gin is a distilled alcoholic beverage that has it's origin in medicinal liquor made by monks and alchemists across Europe. The historical Gin producing regions are Southern France, Flanders and Netherlands. Gin was originally created to provide aqua vitae from grape and grain distillates.

During the Middle ages, the newly found substance Ethanol was considered by Alchemists to be the water of life, and an aqueous solution of ethanol was in use all over Europe and had different names and is literally the origin of many spirits like Whisky ( from the Gaelic uisce beatha for water of life ). Today Gin is produces from a wide range of ingredients, which gave rise to numerous distinct styles and brands. The predominant flavour of Gin is from the Juniper berries and then each different distillery flavours it further with an assortment of botanicas or herbs, spices, floral and fruit flavours, in different combinations. Gin is commonly drank mixed with Tonic water but it is also often used as a base spirit for many gin based flavoured liqueurs like Sloe Gin.

Wild Turkey 80 Proof Bourbon

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)
