They call it bartender’s ketchup, but if you’re wondering what all the fuss is about, read on.

Hold up, one of the most popular liqueurs in the world is made out of – checks notes – flowers? Yep, that’s right. And despite how that may sound, it’s actually delicious. We’re talking about the sweet and versatile elderflower liqueur, AKA “bartender’s ketchup”. After a little dip in popularity in the 2010s, the elderflower flavour made a triumphant return to the masses with the success of its flagship cocktail, the Hugo Spritz, AKA Elderflower Spritz. Gone are the days of being a bartender’s best-kept secret – elderflower liqueur is here to stay.
A short history on elderflower liqueur

While branded elderflower liqueurs like St Germain are a fairly new invention, the flavour has been with us for centuries, mostly as a cordial across northern Europe. Elderflower has even been sipped as far back as Roman times. In other words, she old. The modern grown-up iteration was devised much later, around 2007 when the son of Chambord-glory and third-generation distiller Robert J. Cooper ventured out on his own to create St Germain (despite his famous father’s misgivings). 

The name St Germain is pretty unique. Turns out old Robbie J. has a soft spot for the French creatives. The St-Germain-es-Prés area was once the artistic epicentre of Paris, housing notable famous artists and novelists such as Hemingway, Picasso, Baudelaire and others. Robert was inspired to capture that creative juju in his St Germain liqueur, even shaping the bottle to be in the art-deco style in a li’l wink and a nod to the neighbourhood’s aesthetic.

How is elderflower liqueur made? Elderflower liqueurs are obviously made from elderflowers, but how does that happen? These flowers are actually a big deal. They are all handpicked and harvested from the foothills of the French Alps, and they only flower in spring. And just to make things even trickier, they’re at their ripest for just one week. French farmers hand-harvest them and then race against the clock to capture the unique fragrance and flavour of the ripe blossoms. They are then macerated in grape-neutral spirit within 48 hours of being picked, usually for about a few days but some liqueurs for up to several weeks. After that, the sugar element is mixed in, and sometimes some lemon, too. 
What does elderflower liqueur taste like? Elderflowers have an intriguing aroma and flavour, and elderflower liqueur is no different. The liqueurs are sweet, but not overly so, and they have a beautiful floral element, almost like honeysuckle, which is all balanced out with some subtle citrusy notes like lemon zest. If you really pay attention, your tongue can pick up passionfruit, pastry and even lemon-meringue pie flavours. Because of this, elderflower liqueur not only works with most spirits, but also most white fruit flavours like apple, pear and grapes, hence the name bartender’s ketchup.
How do you use elderflower liqueur?

There are loads of briliant cocktails that use elderflower liqueur. First up, we have that much-loved Hugo Spritz. Delicious, refreshing and super light – it gained traction on TikTok a few years ago and shows no signs of slowing. We also have the Elderflower Martini – a floral take on the OG, this is mixed up with vodka instead of gin, and the liqueur gives this drink a very pretty twist. Ava Matthew’s Basil and Elderflower Spritz cocktail is great for serving a few peeps, especially as it is wonderfully simple. Cara Devine’s Gin Sour with Celery Bitters is a great savoury and floral way to showcase the liqueur. One of our favourite elderflower cocktails is the Courtside. Pretty in pink, sweet and fruity, this is everything you want in a drink. Then you have the Elderflower Lemon Sour, which is super easy and lower in alcohol, and the White Linen, which might just be the perfect party pour. 

But if you want to keep it even easier, try mixing some elderflower liqueur through your Gin and Tonic, your vodka, lime and soda, or perhaps even add a splash to your ice-cold soda water and you’ll see just how much this versatile liqueur has to offer.

This Melbourne-made treat is only available via Dan’s Marketplace and not in stores, so it gets shipped straight from Marionette. But don’t let that stop you because this is work a closer look. We know we said elderflowers come from the French Alps, but the clever peeps at Marionette have used Victorian flowers. Expect blossom and nectarine, honeyed apricot and crisp acidity.
