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)

Dry Vermouth

Vermouth the French for German Wermut, Wormwood in English, is an aromatic fortified Wine, flavoured with various botanicals like roots, barks, flowers, herbs, seeds and spices.

Although traditionally Vermouth was used for medicinal purposes, it has been also served as an apéritif in its modern avatar. The modern Vermouth first appeared in and around the 18th Century in Turin. By the late 19th Century it became very popular with bartenders as a key ingredient in cocktail mixology.

Martini, Manhattan, Rob Roy and Negroni were a few cocktails that Vermouth grew in popularity with. But later during the 20th Century, Vermouth slowly lost its glory and Dry Martinis and extra Dry Martinis with little or no Vermouth gained over the original Martini. Modern Martinis usually have a splash of Vermouth to add that herbacious texture to it.

Historically, there have been two Vermouth types, Dry and Sweet, but with demand variations have come up now. that include extra-dry white, sweet white, red, amber and rose.

Vermouth is produced by adding proprietory mixture of aromatic botanicals to a base wine or a base wine plus spirit or spirit only, which is usually redistilled before adding it to a base of neutral grape wine or unfermented wine must ( freshly pressed grapes and the juice ). After the wine is aromatised and fortified. it is sweetened and the end product is a Vermouth.

Dry Vermouth is what makes the character of the original Martini, and a Dry Vermouth has less sugar and is more herbacious but less spicier than Sweet Vermouth.

Orange Curacao Liqueur

Curaçao is a liqueur flavored with the dried peel of the bitter orange laraha. It's been a popular liqueur for more than 150 years, the Dutch East India Company created this orange liqueurs by steeping orange peels in alcohol from the island of Curaçao and called it Curaçao liquor, unlike Triple Sec, Curacao has added spices and herbs to the orange and Curaçao comes in a variety of colours such as clear, orange or blue.

Blue Curaçao being the most used of them, in cocktails. Although Curacao is an orange tinted liquor, Blue Curacao is a regular Curacao dyed bright blue to give it a striking appearance, and thus is a very popular cocktail mixer, whenever a striking colour is desired.

Blue Curacao is usually around 25% ABV.

Blue Curacao is essentially Orange Liqueur tinted Blue, the colour doesn't influence the taste and thus Orange Curacao is interchangeable with Blue Curacao in recipes, if the colour is not important in the appearance.

NOTE: Blue Curacao being an Orange Flavoured Blue Liqueur, it's primary purpose in a cocktail is introducing the Orange flavour and the striking sky blue to the drink, so, if a bottle of Blue Curacao liqueur is something you are not planning to buy right now, you can manage with the Blue Curacao Syrup.
It would add the same flavour and colour profile to the cocktail, all we need to do is simply count for the alcohol absent in the syrup and account for it.

Grenadine Syrup

Grenadine is a common non-alcoholic pomegranate syrup with a characteristic deep red colour. It is a very popular cocktail ingredient, used for its pomegranate flavour and more for its ability to add a reddish to pink tint to a cocktail.

The name Grenadine originates from the French for pomegranate, which is grenade.

Grenadine is not subjected to regulations like alcoholic beverages are, and there are no region specific formulae any more, and thus manufacturers often replace pomegranate with blackcurrant juice and other fruit juices while retaining the same flavour profile.

Many producers now use artificial ingredients like high fructose corn syrup, water, citric acid, sodium citrate, sodium benzoate and food grade red colour along with natural and artificial flavours.
