Feisty Protein Soda Crashes the Luxury Aisle
Feisty Protein Soda has infiltrated the shelves of the UK’s most luxurious and prestigious department store.
The playfully rebellious newcomer recently announced a landmark listing at Harrods, just over a year after launch.
“Yes… the Harrods,” founder Vy Cutting wrote in a post on LinkedIn.
“The home of artisan cheese and fine patisserie, now stocking protein soda?”
Feisty’s “world first” protein soda has quickly been gathering pace — especially on TikTok.
Naturally sweetened with fruit juice and stevia, low in sugar, and easy on calories, it burst onto the scene with a squeaky-clean formula and plenty of unpolished attitude.

Promising to “beat the sh*t” out of protein shakes, each can packs 10g of hydrolysed pea protein.
The RTD beverage has already gained a cult following on social media for its Y2K-inspired take on protein.
And it was a rogue DM that sparked the launch at Harrods.
To celebrate the listing, Feisty Protein Soda released a new Green Apple & Lime flavour, accompanied by a fresh recipe.
Larger, 330ml cans were also introduced — and tested by the brand’s TikTok community.
“We invited eight community members into the lab to help us test before production,” Cutting added. “One girl even travelled two hours to vlog it and meet my infamous scientist mum.
“It all started with a random LinkedIn DM from Harrods. Involving real customers to build Feisty has worked. Now Feisty is on their shelves.
“Thank you to the Harrods team for backing Feisty!”
What is Feisty Protein Soda?
Feisty Protein Soda has arrived in the ever-swelling RTD arena as something genuinely fresh — complete with a slightly chaotic backstory.
Cutting, a Central Saint Martins graduate and ex-Louis Vuitton designer, openly admits she wasn’t the sporty type.
Instead, she describes herself as “more fashion girlie than gym rat.”
But after undergoing two successive knee surgeries, she found herself in chronic pain and diagnosed with arthritis.
The shock diagnoses led her down the path of strength training, which is where her passion for protein began.
Unimpressed by chalky protein powders and dense bars that, she says, were geared towards gym bros, Cutting set about creating something slightly more chic.
And so, in the intersection of fashion and function, Feisty was born.
But before Cutting even had a recipe for Feisty Protein Soda nailed down, Selfridges came knocking.
That led to her mum, a PhD scientist, jumping on board to take care of the formulation.

Feisty was pulled together in the nick of time for its Selfridges debut, and it’s been going from strength to strength ever since.
The three-piece flavour lineup is made up of White Peach & Nectarine, Sour Cherry & Blackcurrant, and the newly released Green Apple & Lime.
Cutting’s mum is still very much involved with the formulation. She’s now also ingrained in the brand’s attitude-heavy approach, even donning a MILF (Man, I Love Feisty) t-shirt for a recent promo shoot.
And the recipe, Cutting says, is almost reaching its final form.
“We — well, my mum — has been working day and night perfecting the ever-so-challenging ‘protein soda’,” she continued.
“We’re now on iteration 105, inching closer to that ‘just-like-a-soda’ taste.
“Since going viral, our TikTok community has grown from 89 to 9,700. Confirming the demand for a plant-based, non-milky protein RTD.”
Feisty Protein Soda is a fun, off-script introduction to the functional drinks space.
The public image is refreshingly rough around the edges, and this recent deal with Harrods proves that even the establishment has a taste for a little mischief.
Packs of 12 cans are available via Feisty’s website for £28.20 as a one-time purchase, or £22.56 with a subscription. Smaller 9-can packs are also available.
