The origins of the Pisco Sour are shrouded in mystery, in many ways it’s an evolution of the classic Whisky Sour but it also has a vibrant and complex history all of its own. It’s the national drink of both Peru and Chile, and both countries lay a very real claim to its origin story. Regardless, the Pisco Sour is a bartender favourite worldwide with its bright, floral aroma and tart citrus punch. Let’s explore what makes this cocktail one of the world’s finest, and how to make a perfect Pisco Sour.
Ingredients and Top Tips
Like all the world’s best cocktails, the Pisco Sour is simple in concept, but complex in the balance, aesthetic and general preferences. For simplicity, let’s break the Pisco Sour down to its core ingredients:
Pisco
Well, obviously. The Peruvian national spirit, distilled from grapes and oozing with light, floral flavours is the base for the classic Pisco sour. For a drink with a serious punch, we’ll be looking at around 60ml or 2oz of your favourite Pisco. Don’t be afraid to lighten the load to 50ml or 1.5oz, but any lower and the later measurements may become complicated - you want the drink to at least fill the glass right?
Citrus
To lemon, or to lime? That is the question. The Pisco Sours’ much older “father cocktail” - the whisky sour - calls for lemon, however the lighter, fruitier notes of pisco lend themselves to lime juice. That’s fresh lime juice, folks.
Sugar
Put down that £20 bottle of store bought sugar syrup! For this recipe, all you need is a rich simple syrup. Simply dissolve 500g of sugar in 250ml of boiling water, bottle, and away you go. Some purists swear by powdered sugar directly into the cocktail shaker for a Pisco sour, however this can create inconsistencies. Inconsistency can be beautiful when experimenting with cocktails alone, but there are better options for when you have to whip up a few of these for a party.
Foamer
A small amount of egg white goes a long way, and in our humble opinion, makes for the perfect consistency in a Pisco Sour. Don’t worry, egg whites are off-putting to some but they are used in cocktails in all your favourite bars. Still not convinced? Try vegan foaming bitters such as Mrs. Betters’ Bitters. Be aware that this will impact the flavour of your cocktail.
Bitters
The classic recipe calls for a few drops of Angostura bitters to add depth, balance and richness to the cocktail. If you have them to hand, a grapefruit bitters or orange bitters may better complement the Pisco Sours' more fruity floral notes.
How do Bartenders Make a Pisco Sour?
We challenged three brilliant bartenders from some of the UK’s best bars to answer the question - what makes a perfect Pisco Sour?
Mia - Satan's Whiskers (London)
The world renowned Satan’s Whiskers changes its menu each and every single day. We were lucky enough to visit on a day when Mia was serving up a far from traditional frozen Pisco Sour. When asked what inspired her to include this frosty treat on her menu, she quite rightly stated “If you can, you should”. This blended delight was floral, tart and refreshing and reminded us that while tradition is important, it’s equally important to break those boundaries and just have fun with cocktails. The perfect Pisco Sour? Well, it’s the one you want to make.
Ais Stevenson - The Maven (Leeds)
Ais - creative cocktail master from Leeds’ Maven bar - points out that few drinks in the “floral-sour” category have stood the test of time quite like the Pisco Sour. For them, a perfect Pisco Sour calls for pisco, lime, sugar, egg and orange blossom to sub the classic angostura bitters. “Always wet then dry shake.” - Wet shaking refers to shaking a cocktail with ice, and dry shaking without. The perfect texture and foam is created by first shaking with, and then without, ice. Why? That’s a whole other article.
James Plant - Albert’s Schloss (Liverpool/Everywhere)
An expert in all things cocktails, art and all things delicious, James believes (like all cocktails) that the perfect Pisco Sour relies on attention to detail. “You can’t produce a world class drink unless every aspect is great.” from the Pisco, citrus and even the glassware. James is particularly fond of using both lime and lemon for a sharper, more complex Pisco sour. Remember folks, while there are alternatives out there for that classic velvety texture, for James, “You can’t beat egg whites.” - no pun intended.
Four Piscos that make a Perfect Pisco Sour
To make the perfect Pisco Sour, you need a perfect Pisco. Here are four perfect Pisco picks:
Barsol Primero Quebrenta
Barsol are world leaders in the Pisco game, and their signature spirit made from the less aromatic Quebrenta grapes proves exactly why. The rich notes of banana and chocolate add a full body to the Pisco sour that some lighter, more floral bottles may lack. This is Pisco made by people that love the Pisco Sour, for the purpose of being used in a Pisco Sour. It’s easy to see why this is the bartender's choice of spirit in countless bars.
Size: 700ml
ABV: 41.3%

Demonio de Los Andes Acholado
“Devil of the Andes” Pisco comes in at a lower price point than many bottles, but doesn’t even slightly skimp out on flavour, with a heavy grape punch on the palette coming from the varied selection of grapes used to make this fine spirit. The producers, Vina Tacama, claim to be one of the oldest vineyards in Peru, and Demonio de Los Andes lives every bit up to that hype. The particularly potent grape punch pairs perfectly in the Pisco Sour. Try saying that three times drunk.
Size: 700ml
ABV: 40%
Find here: £32.95
Macchu
Sporting the cutest label of all the Piscos, Macchu’s grassy, floral and limey signature spirit makes for a world class Pisco Sour. Ten whole pounds of the most “awesome grapes” (their own words) go into each and every bottle of Macchu, which contributes to the clean, crisp flavour and smooth sipping experience. The spirit is left to rest for a year in a clay pot before bottling. Clearly, Macchu is a labour of love from sisters Melanie and Lizzie; their passion for distilling shines through in any cocktail.
Size: 700ml
ABV: 42.2%
Find here: £37.24
Campo de Encanto
Campo de Encanto (field of enchantment) is a stand-out bottle for those looking for sustainability within their spirits. The discarded grape skins are used as compost and fertiliser for their later harvests, creating an almost zero-waste life-cycle for this sweet, fruity pisco. As Pisco is largely an unaged spirit, environmental factors contribute hugely to the final flavour, which is evidenced by Campo de Encanto. Add this to your pisco sour if you’re a lover of fruit-forward cocktails and want something different, with hints of plum, lemon and tropical fruits.
Size: 700ml
ABV: 40.5%
