History of kefir
Origins in the Caucasus Mountains
Kefir originated in the mountains of the North Caucasus, where it has existed since ancient times. The Ossetians, descendants of the nomadic Scythians, were among the first to use kefir grains to ferment milk.
At the time, milk was fermented in animal skin bags, left in the sun during the day and hung up at night. The inhabitants regularly stirred the milk and added fresh milk, thus maintaining continuous fermentation.
Kefir grains, often called "Grains of the Prophet," were considered a family treasure. Legend has it that the prophet Muhammad gave these grains to the peoples of the Caucasus. These ancestral practices then allowed kefir to spread throughout the world.
Global development
The inhabitants of the Caucasus jealously guarded the secret of the grains, fearing that sharing them would diminish their benefits.
A key moment came in 1908, when the Blandov Dairy in Moscow launched commercial production of kefir. This was made possible thanks to Irina Sakharova, who managed to obtain the grains from Prince Bek-Mirza Barchorov.
Kefir has also attracted the attention of scientists, notably thanks to Dr. Ilya Ilitch Metchnikoff. In 1907, in his book La Prolongation de la vie (The Prolongation of Life), he established a link between kefir consumption and the exceptional longevity of the Caucasian population.
| Period | Key event | Impact |
|---|---|---|
| 1908 | Start of commercial production by Laiterie Blandov | Large-scale introduction of kefir in Russia |
| 1930 | Launch of industrial production | Wide distribution throughout Russia |
| 1988 | Production record | More than 1.2 million tons produced annually |
In 1973, Irina Sakharova was recognized for her essential role in the history of kefir, receiving thanks from the Soviet Minister of Food Industry for her "heroic efforts." Today, kefir has established itself on the global market, with forecasts of €2.65 billion by 2028, representing an estimated annual growth rate of 7.4%.
Making kefir at home
Kefir, an ancient drink, can be easily prepared at home by following a few simple steps and using the right equipment.
Required equipment and ingredients
To prepare kefir, you will need a few essential tools: a glass jar, a non-metallic strainer, a breathable cloth or coffee filter, and a rubber band.
The main ingredient is, of course, kefir grains. In France, several suppliers offer handy kits:
| Supplier | Kit contents | Special features |
|---|---|---|
| L'Atelier du Ferment | Kefir grains, lemons, dried figs, guide | Artisanal production in Mayenne |
| Symbiose Kefir | Kefir grains, detailed guide | Free access to the Kéfir Academy |
Here is what L'Atelier du Ferment says about their kit:
"Our kefir making kit contains everything you need to make your own homemade drink!" - L'Atelier du Ferment
Once you have all the equipment you need, all that's left to do is get started. To make kefir at home, it's essential to have the right accessories, just like with matcha, where Japanese matcha tea sets are recommended for an authentic experience.
Production method
Start by adding 1 to 2 teaspoons of active kefir grains to one litre of fresh milk (avoid ultra-pasteurized milk). Cow's or goat's milk is perfectly suitable.
Cover the jar with a cloth or coffee filter held in place with a rubber band. Place the jar in a temperate location, between 68°F and 84°F. Fermentation usually takes between 12 and 24 hours.
You will know that the kefir is ready when the milk thickens slightly and gives off a pleasant smell. Then filter the mixture using a non-metallic strainer to collect the grains, which can be reused immediately for a new batch.
Key success factors
To make your kefir a success, keep these important points in mind:
- Temperature: Maintain a stable room temperature between 20°C and 27°C. Variations can disrupt fermentation.
- Ingredient quality: Use fresh, non-ultra-pasteurized milk to promote the development of probiotics.
- Hygiene and equipment: Choose glass, wood, or stainless steel utensils and avoid metal, which can damage the beans. Make sure all your equipment is clean to prevent contamination.
Symbiose Kéfir also emphasizes the importance of creating a community around kefir:
"True to the tradition of kefir, Symbiose brings together a community of enthusiasts around a Kefir Academy. What for? To help them get started making their first kefir at home, share recipes and tips... and also provide them (free of charge) with the essential ingredient for this extraordinary drink: kefir grains!" - Symbiose Kéfir
If your kefir becomes too thick or separates, it means that fermentation is taking a little too long. Simply adjust the time on your next attempt.
Health effects
Kefir is known for its positive health effects.
Benefits for the digestive system
Kefir contributes to intestinal health thanks to its many natural probiotics. Among them, Lactobacillus kefiri plays an important role in limiting the proliferation of harmful bacteria such as Salmonella, Helicobacter pylori, and E. coli.
For people who are lactose intolerant, kefir is easier to digest. The bacteria it contains naturally break down between 20 and 30% of the lactose present. These digestive benefits also contribute to a better functioning immune system, as we will view later.
The probiotics in kefir promote good digestion, just as the antioxidants in matcha tea help improve digestion.
Immune system support
Kefir helps strengthen the immune system in various ways. The probiotics it contains help balance the intestinal flora, which is crucial for strong defenses. In addition, recent searches show that kefir can reduce inflammation associated with allergies and asthma, thanks to the bioactive compounds produced during fermentation.
| Effect on immunity | Mechanism of action |
|---|---|
| Intestinal protection | Strengthening the intestinal barrier |
| Reduction of inflammation | Regulation of the immune response |
| Defense against microbes | Production of antimicrobial substances |
Nutritional information
One serving of kefir (240 ml) contains:
- Superior quality proteins
- B vitamins
- Easily absorbed calcium
- Essential minerals
To get the most out of kefir, start with small quantities and increase gradually. If you have a weakened immune system or histamine sensitivity, consult a healthcare professional before consuming it regularly.
Like kefir, organic premium matcha tea from Japan is recognised for its many health benefits, including its high content of antioxidants.
Daily usage guide
Ways to use kefir
Kefir can easily replace butter, yogurt, or crème fraîche in your recipes. Here are some practical ideas:
In savory dishes, it adds a creamy texture. For example, in a Mac and Cheese recipe, kefir combined with farmhouse cheese makes for a rich and flavoursome sauce. For soups, such as roasted tomato soup, it adds a light and refreshing acidity.
On the sweet side, kefir is just as versatile. You can use it to:
- Smoothies and milkshakes
- Breakfast bowls with fresh fruit
- Frozen desserts (by freezing them in ice cube form)
- Pastries, instead of milk
These ideas are accompanied by specific advice on quantities and the best ways to store it.
Consumption recommendations
| Phase | Daily quantity | Duration |
|---|---|---|
| Introduction | 100 ml | 1 week |
| Adaptation | 150–200 ml | 2 weeks |
| Maintenance | 200–300 ml | Continuous |
It is recommended to consume between 100 and 300 ml per day, depending on the phase (introduction, adaptation, or maintenance), for at least 3 months to feel the effects. You can also opt for a 5-day consumption cycle followed by a 2-day break.
Storage methods
To preserve the qualities of kefir, proper storage is essential:
- Ideal temperature: 4°C or less
- Shelf life in the refrigerator: 1 to 2 weeks after opening
- Recommended container: an airtight glass container, protected from light
If you want to keep it longer, you can freeze it for up to 1 or 2 months. However, note that the texture may change slightly after thawing.
