How does one properly say goodbye to a monarch that has been around for as long as Queen Elizabeth II? Chances are Liz herself might have suggested a cocktail, as she was known to have appreciated a good drink, particularly one containing gin.

The Queen was not one to turn down a good drink, and was known to enjoy gin-based drinks before dinner. What better way to pay your respect than by raising a glass of something royal?

Here's our guide to five cocktails that you can toast the Queen's life with!

The Queen's favorite cocktail only consists of gin and the French apéritif Dubonnet Rouge. The late is monarch is said to have enjoyed the vermouth-like drink, also a favorite of her mother's, mixed with a third of gin.

One part gin and two parts Dubonnet Rouge make a decent Dubonnet, explains Matthias Knorr, founder of a barkeeping academy in Munich, Germany.

You shouldn't shake the cocktail but stir it on ice for a good while, he says, to prevent the ice from diluting the flavor. Knorr recommends about 1.5 cups of ice for 1 ounce of gin and 2 ounces of Dubonnet. The drink is then poured through a sieve into a stem-glass that's been pre-cooled – preferably even pre-frozen – and served without ice.

Add a wedge of lemon to round off this cocktail, which the Queen is rumored to have enjoyed before dinner.

If you can't find any Dubonnet (there are already reports of it being sold out in Australia, for example), there are two other royal gin-based options.

Elizabeth II apparently also enjoyed a stronger version of this classic in the afternoon, according to Knorr. It contains 2 ounces of gin and 2 dashes of vermouth.

"This drink, too, is chilled on ice and then strained into the pre-chilled glass and decorated with lemon zest or slice. Place some olives next to it, which can be put in the drink or eaten with the drink if preferred," the barkeeper added.

If you don't want to go all in and you'd prefer a more restrained drink to toast the Queen, then mix yourself a gin and tonic. But this classic also comes with its pitfalls. "It's all about the right ratio of gin and tonic," Knorr warns. When using too little ice or too much tonic, you can drown the gin.

His recipe: 1.5 ounces of London Dry Gin and 3.5 ounces of tonic water, tipped over 4 ice cubes. And don't forget a slice of lemon at the end.

And for those who don't like gin, here are two more recipes for a royal farewell drink.

No, King Charles III – formerly the Prince of Wales – has nothing to do with this drink, served in style in a silver cup. It's said to be a personal creation of Queen Victoria's eldest son, Albert Edward, who later became King Edward the VII.

First, briefly shake about 1/2 ounce of cognac, 1/4 ounce of orange liqueur and 2 dashes of Angostura bitters. Then pour the mixture flows into the silver goblet filled 3/4 full of ice. Top up the glass with champagne.

To decorate, you can drape a slice each of orange, lemon and lime, and berries on top.

"If you don't have a silver tumbler, you can also use a pre-chilled champagne glass. In that case, however, I would add the ice cubes to the shaker and strain it before topping up with the champagne," is Knorr's recommendation.

A Kir Royale is also topped up with champagne. Before that, you only need to add one other ingredient to the glass – 1/4 ounce of currant liqueur, or crème de cassis.

Knorr says that's more than enough, especially because at one cup of sugar per pint, currant liqueur is almost like a syrup.

Although the drink sounds regal, it was actually invented by a mayor from Dijon, France, whose surname was Kir. Originally, the Kir was made with a Burgundy white wine.

"Legend has it that cassis was added because the wine was probably too acidic for Mr. Kir," explains Knorr. "In the course of time, the wine was then replaced by champagne."

That was tantamount to a promotion and the cocktail became a Kir Royale.
