Pickle cocktails, pickle festivals, pickle coats; pickles have moved from burger garnish to Gen Z obsession. What was once a dependable deli staple has become one of the most talked-about flavours in food, fashion and social media, helped by celebrity endorsements, viral recipes, novelty collaborations and a growing appetite for tangy, briny products.

And for the grocery industry, the opportunity is becoming increasingly difficult to ignore.

Ocado said searches for mini pickles have surged 380 per cent over the past year, while sweet pickle and sandwich pickle searches are up 156 per cent and 627 per cent respectively.

Waitrose has also seen interest rise, with monthly searches for burger pickles up 91 per cent and dill pickles up 25 per cent.

Co-op has now joined the rush with the launch of its Irresistible Dill Pickle Crisps as part of its 2026 summer range, after searches for “pickle” on its website rose 152 per cent over the year to 26 March.

The limited-edition crisps feature a ridge cut potato base coated with dill and sharp vinegar notes, designed to tap into the bold, tangy flavours gaining traction across social platforms.

“Pickles are having a huge moment and our new crisps hit that bold, tangy sweet spot shoppers can’t get enough of,” said Co-op product developer manager for crisps, snacks and nuts Natalie Dawe.

“We know our crisps are cult classics, so we’ve taken a trend that’s exploding online and turned it into something that feels right at home in our range.”

Pickle flavour is also moving well beyond crisps. In the US, Smoothie King recently teamed up with Grillo’s Pickles to launch a limited-edition pickle smoothie, blending real pickles with banana, organic kale and coconut water.

The 20-ounce drink is positioned around hydration as much as novelty, with Smoothie King pointing to pickles’ ‘electrolyte credentials’ as part of the launch.

Smoothie King vice president of research and development Lori Primavera said pickles were “not only delicious and having a cultural moment”, but also offered nutritional benefits linked to hydration.

Grillo’s, which began as a wooden cart in Boston in 2008 before growing into a national pickle brand, has leaned hard into unusual collaborations. It has already worked with Burt’s Bees on a cucumber dill lip balm and Pabst Blue Ribbon on a pickle-flavoured beer.

Its chief commercial officer Mark Luker said the brand liked to do “unhinged collabs”, but added that the Smoothie King partnership offered the chance to talk about the functional benefits of pickles too.

The trend has also crossed into fast food and marketing theatre.

KFC UK & Ireland has unveiled a one-off Pickle Puffer jacket, filled with sliced gherkins and brine, and fitted with a straw so fans can sip pickle juice on the go. The stunt has been designed to promote a limited pickle menu, including Pickle Loaded Fries and Pickle Pepsi.

KFC UK & Ireland brand manager James Channon said, “It’s a bit unhinged, but that’s the point.”

That word, unhinged, goes some way to explaining why the pickle has become such a neat fit for Gen Z food culture.

Pickles sit at the centre of several overlapping trends. They are affordable, visually distinctive, shelf-stable, sharp-tasting and a little bit divisive. They can be funny, functional and nostalgic at the same time.

They also fit neatly into the messy, chaotic food content that performs well on TikTok. Dua Lipa’s widely shared recipe for Diet Coke mixed with pickle brine and jalapeño juice helped push the flavour further into mainstream conversation, while Pamela Anderson has launched a pickle brand of her own.

Eloise Gendry-Hearn from marketing agency The Digital Fairy said pickles had benefited from Gen Z’s embrace of “grossness”, chaos and shared “ickiness” online.

She described the pickle as “to Gen Z what avocados were to millennials”, positioning it as an accessible and meme-ready food whose simplicity is part of the appeal.

The trend is also being pulled into real-world events.

The Big Brine, Picklefest and Pickle Festival are among the events looking to cash in on growing demand for pickle-led experiences. The Big Brine, which will take place in Hackney in September, is pitching itself as an end-of-summer celebration combining food, DJs, picklebacks and drag entertainment.

Tickets cost £20, with organisers targeting a young audience and hoping to bring fermenting, pickling and brining to a wider crowd.

The Big Brine co-founder Mitra Esmizadeh said there was “definitely a gap in the market” for an event built around the trend.

The movement has also been boosted by the long-running pickle festival at the Dog and Bell pub in south London, which has grown from a small local gathering into a highly visual event attended by thousands.

Other pickle festivals are now planned in Berkshire, Walthamstow, Manchester and elsewhere this summer.

There’s obviously a growing movement of vitality and popularity for pickles. However, the challenge for grocers will be knowing how far to push this weird and wonderful embrace of a deli staple.

A dill pickle crisp or burger pickle line can feel timely and commercially sensible, whilst pickle smoothies, pickle Pepsi or brine-filled jacket is designed to generate conversation first and repeat purchase second.

But that may be exactly why the trend is working. In a market where shoppers are still watching budgets closely, a relatively cheap, funny and flavour-packed product can offer a small sense of novelty without requiring much commitment.

As summer ranges battle for attention, pickles offer something many retailers want. They are affordable, recognisable, bold and highly shareable.

The humble gherkin may not stay at the centre of youth culture for long. But for now, grocery has a clear chance to turn brine into business.
