Science Of Mint Julep Cocktail: Exploring Flavours, Temperature Dynamics And More
The origins of the classic ‘julep’ can be traced back to a time in the 18th century in the American South when the word referred to a drink made by mixing a spirit with sugar and water. Eventually, mint was added to this concoction by American farmers who could harvest this herb fresh from their small home gardens, for adding to iced teas and other chilled blends.
Soon after, bourbon production began to proliferate across different regions in this country and American cocktail cultures came up with the mint julep prepared with the addition of 30 ml bourbon to a mix of muddled mint leaves and about 1 tablespoon simple syrup. This mixture was served on a bed of crushed ice and garnished with mint leaves or lime wedges to make the cool mint julep as it is recognised today.
Complete with a complex combination of smoky, fruity and peppery flavours, mint julep is best served chilled and is well-suited as a drink prepared at a summertime cocktail gathering or a garden party hosted outdoors. It is a drink filled with layered tasting notes that become more pronounced with the addition of crushed ice and preparing a balanced mint julep means understanding the science behind the interplay of these different cocktail ingredients which come together in a balanced flavour blend.
Bourbon’s Robust Flavours
For exploring the flavours in the mint julep, one must first begin with the base spirit. Good quality bourbon, when added to a cocktail shaker lends the drink its quintessential smoky, vanilla-like, oaky and spicy note which is responsible for bringing much depth and potency into the blend’s flavour profile.
Sometimes, a hint of dried fruit introduced into the drink through aged bourbon creates another layer of flavour in the cocktail that imbues it with much richness and depth. About 30 ml premium bourbon thus added to a classic mint julep becomes one of the most integral elements of this cocktail concoction.
Peppery Mint Contrast
As well, what makes the drink such a standout is pairing the deeply flavoured and earthy bourbon with lots of muddled mint leaves that are complete with a peppery and sharp edge. Green and fresh, mint brings a lot of brightness into what is otherwise a rather deep flavour, to furnish a stellar contrast of these opposing tasting notes.
The science of adding mint in a mint julep thus revolves around these sharp and mildly spicy flavours which cut through the potent and tart notes of the bourbon to introduce a bit of zinginess into the overall effect of the cocktail.
Adding Simple Syrup
Another important flavour component in a classic mint julep recipe is a spoonful of simple syrup. This introduces a sweet and syrupy texture which balances out the spicier and peppery compounds in the cocktail to give it a fuller flavour. With the addition of simple syrup the drink becomes a combination of tart, earthy, minty and sweet flavours that give mint juleps a well-rounded finish.
Simple syrup in the cocktail also accentuates the flavours of the muddling mint while cutting through the tartness of the bourbon to bring forth a very uniform and perfectly flavoured blend.
Crushed Ice For Dilution And Temperature
One of the most important ingredients in a classic mint julep, crushed ice at once plays two roles – that of keeping the drink chilled and of becoming a mixer which tones down the more pronounced flavours of bourbon and mint leaves.
The science of adding crushed ice to the cocktail is then centred on determining the speed of dilution which will ultimately soften the flavours in the drink to deliver a chilled, slushy-like mix complete with a full and rounded taste that makes the cocktail a favoured option as a summertime drink at a cocktail party or gathering.
