The kefir renaissance

Kefir has moved from regional specialty to one of dairy’s fastest-growing categories. Global launches rose 15.7% in the first half of 2025 (Mintel GNPD), driven by gut health, demand for traditional fermentation and a wave of new formats. For manufacturers, the opportunity now sits in how consistently that experience can be delivered.

Why one of the world’s oldest fermented drinks is becoming one of dairy’s biggest opportunities 

Few fermented dairy products have traveled a journey quite like kefir. Originating in the Caucasus Mountains, where kefir grains were traditionally used to ferment milk into what became known as the ‘drink of bliss’, kefir remained a regional specialty for centuries.  

Today, however, it is emerging as one of the most dynamic categories in cultured dairy, driven by consumers looking for foods that combine fermentation heritage, functional nutrition and authentic provenance. 

For dairy manufacturers, the resurgence of kefir represents far more than another product trend. It reflects a convergence of long-term consumer shifts that continue to reshape the cultured dairy category and create new opportunities for innovation. 

That momentum is increasingly visible on supermarket shelves around the world. According to Mintel GNPD, global kefir launches increased by 15.7% during the first half of 2025 compared with the same period in 2024, while established brands and retailers continue to expand their portfolios across Europe, North America and Asia. In the UK, a range of companies have introduced new kefir products in response to growing consumer demand for fermented dairy and digestive wellness.

A category driven by multiple consumer trends 

Interest in gut health remains one of the strongest drivers of functional food innovation, with consumers increasingly recognizing the relationship between digestive health and overall wellbeing. At the same time, demand continues to grow for products perceived as minimally processed, familiar and made using traditional production methods. Kefir occupies a unique position at the intersection of these trends, offering a product with centuries of heritage alongside a fermentation process that consumers increasingly associate with authenticity and wellness. 

Manufacturers are also benefiting from consumers seeking products that deliver multiple benefits within a single purchase decision. Alongside digestive wellness, brands are increasingly positioning kefir around protein, fiber and broader functional nutrition, with recent launches including high-protein formulations, kefir shots, products containing added inulin, and even beverages supporting cognitive health. Rather than being confined to the dairy aisle, kefir is becoming part of a broader movement toward everyday functional nutrition. 

Innovation is expanding the boundaries of kefir   

Innovation is also reshaping the category itself. Traditional plain kefir continues to perform strongly, particularly across Eastern Europe, but manufacturers are rapidly expanding into fruit variants, indulgent dessert-inspired flavors, sparkling beverages and frozen desserts. Plant-based kefir, produced from alternative substrates including coconut and grains, is opening the category to entirely new consumer groups. 

The result is that kefir is no longer a single product with a single consumer. It has become a versatile fermentation platform capable of addressing a wide range of health, lifestyle and sensory preferences. 

Kefir growth creates new manufacturing challenges 

As consumer expectations continue to evolve, so too do the demands placed on manufacturers. 

Although consumers increasingly value kefir for its fermentation heritage, very few appreciate the complexity required to produce it consistently at commercial scale.

Unlike many cultured dairy products, those microorganisms continue to interact throughout production and storage, making kefir one of the most technically demanding fermented dairy products to manufacture consistently. 

For manufacturers, every decision influences the final product:

• Fermentation temperature affects flavor intensity and gas formation,
• Maturation helps develop the characteristic sensory profile
• Cooling conditions, milk composition and processing methods all contribute to texture, acidity and shelf-life performance. Even seemingly small adjustments can produce noticeable differences in flavor, mouthfeel and consumer perception. 

These challenges become even more significant as manufacturers seek to innovate. Developing a high-protein kefir, reducing carbonation for consumers unfamiliar with traditional products, or creating formulations for different regional markets all require careful control of the fermentation process without losing the authenticity that makes kefir unique. 

From opportunity to competitive advantage  

Successfully responding to these challenges requires much more than following market trends. It demands a deep understanding of fermentation science and the ability to translate that knowledge into products that consistently meet consumer expectations. This is where experience becomes a genuine competitive advantage.

With more than 80 years of expertise in fermentation and one of the industry’s broadest portfolios of kefir cultures, IFF works with dairy manufacturers around the world to help translate consumer insights into commercially successful products. Our portfolio spans traditional cultures produced from freeze-dried kefir grains through to multi-species culture systems designed to deliver specific flavor, texture, shelf-life and processing characteristics, allowing manufacturers to create products tailored to local markets while maintaining consistent production performance.

As consumer interest in kefir continues to accelerate, the question is no longer whether there is an opportunity within the category, but how manufacturers can differentiate themselves while delivering the authentic sensory experience consumers increasingly expect.
