Introduction to a Fermentation Journey
A road trip through the Scottish Highlands, with jars of sauerkraut and kimchi stored in the boot of a car, may seem an unusual origin for a business venture.
However, human nutrition students Madi Myers and Arthur Serini understood that these jars would remain preserved without refrigeration and serve as their primary vegetable source during a three-week journey.
Fermented foods such as sauerkraut, kimchi, sourdough, yoghurt, and miso are known to benefit gut health. Researchers are increasingly exploring their connections to chronic diseases, as noted by James Kinross of Imperial College Healthcare NHS Trust.
Growing Interest in Gut Health and Wellbeing
Dietitian Aisling Pigott has observed a shift over the past decade from simplistic "diet culture" towards a more genuine focus on longevity and wellbeing.
Welsh producers are tapping into this trend, offering products ranging from goat's milk kefir in Ceredigion to fermented vegetables made from allotment leftovers on Anglesey, and kombucha from Conwy.
"Like any 'trends', as consumers we can often fall into traps when it comes to wellness," said Aisling.
"We've seen menowashing of products, protein packed chocolate bars and skin-care for children.
Sometimes the simplest messages around wellbeing, eat fresh food, move our body, sleep and hydrate, can be lost amongst the glittery packets and Instagram campaigns."
She attributes the surge in fermented food popularity to increased awareness of gut health's role in overall wellbeing.
"Young people are more health conscious," she added.
Nonetheless, Aisling cautions that despite the benefits of fermented foods, maintaining a healthy, balanced diet remains essential.
The Birth of The Crafty Pickle Co
"It was around 2017 when the idea of the business kind of came up and it was after we travelled through the Scottish Highlands with a couple of jars of sauerkraut and kimchi in the boot of Madi's car," Arthur Serini explained.
"And it just allowed us to have a nutritious source of veg on the road for about three weeks and it just kept surprisingly well."
This experience occurred while the couple were pursuing master's degrees in human nutrition at the University of Aberdeen.
From this, The Crafty Pickle Co was established, now operating on a farm in Monmouthshire. The initial focus was on reducing food waste rather than promoting health benefits.
"In the beginning, the aim was to preserve food to make it last longer," Arthur said.
"So we do not necessarily want to skip all the health jargon, but more focus on rescuing food that would have otherwise gone to waste."
The company produces three varieties of sauerkraut and two types of kimchi, creating seasonal batches from surplus vegetables that might otherwise be discarded. A portion of sales is donated to the hunger and food waste charity FareShare.
In addition to supplying shops and restaurants and conducting workshops that sell out months in advance, Arthur notes that public understanding often lags behind enthusiasm.
What is Fermented Food?
Fermentation is one of humanity's oldest food preservation methods, predating refrigeration and freezing.
Historically, vegetables were stored in brine, milk was cultured into yoghurt and cheese, and grains were transformed into bread, beer, and wine.
For many, the renewed interest in fermented foods represents a return to traditional practices that were once central to daily diets.
Fermented foods are created when microbes such as bacteria or yeast break down food components, enhancing preservation, texture, and flavor.
Home Fermentation and Business Growth
Anna Lloyd began fermenting vegetables at home using surplus cabbage from her father's allotment after growing tired of making jams and chutneys.
"At the beginning I was just making it because it tasted good," said Anna, from Anglesey.
"I didn't realise how ancient this process was, or how important it is for gut health."
What started as a creative experiment evolved into her business Bwblin in 2025.
She now produces small-batch organic wild ferments using seasonal produce and notes that interest spans all age groups.
Children, she observes, are often the most enthusiastic tasters at markets, surprising parents who expect fermented foods to be too sour or unfamiliar.
Anna also spends considerable time educating consumers that many common foods, including yoghurt, cheese, coffee, and chocolate, undergo fermentation processes even if not commonly recognized as such.
The Chuckling Goat and Kefir Production
Further south in Ceredigion, the Chuckling Goat farm exemplifies the sector's growth.
This family-run farm produces goat's milk kefir, a fermented dairy drink rich in live bacteria.
The business expanded rapidly during the pandemic and now serves over 120,000 customers across the UK.
They have diversified into microbiome testing, providing personalized dietary advice based on gut health.
Co-director Shann Jones, who describes herself as an "American city girl who fell in love with a Welsh farmer," discovered kefir after her son Benji developed eczema and bronchial issues following multiple antibiotic treatments.
In 2008, her husband Richard suggested purchasing a goat, as goat's milk is known for being hypoallergenic and beneficial for asthma, eczema, and bronchial conditions.
They acquired Buddug, a black and white Anglo Nubian goat with long floppy ears.
"The goat's milk did help with Benji's bronchial infections. But then there was too much goat's milk," Shann recalled.
By chance, Shann heard a Russian doctor discussing kefir on the radio, which inspired their kefir production journey.
Kombucha and Welsh Craftsmanship
In Conwy, kombucha producer Blighty Booch has also experienced rising demand and notes strong consumer interest in Welsh-made products.
Founder Mark Pavey believes that fermented foods were gradually displaced from everyday diets by convenience foods and supermarket economics, viewing them as the "missing link" in nutrition.
Mark produces craft kombucha from high-quality tea and takes pride in its flavor.
"Supermarkets have side-lined properly fermented products in favour of cheap, shelf stable, ultra processed options," he said.
Conclusion
The growing enthusiasm for fermented foods reflects a broader movement towards sustainable food practices, gut health awareness, and a return to traditional culinary methods. From a Scottish road trip to thriving Welsh enterprises, fermentation is gaining renewed appreciation as both a healthful and environmentally conscious choice.
