We'll explore how to care for your grains, troubleshoot common issues, and provide tips for maximising their growth and vitality. Let's explore the world of kefir magic together and ensure your grains are healthy and happy!

What are water kefir grains?

While the term 'grains' might suggest a plant-based origin, water kefir grains are not grains in the traditional sense. They're a symbiotic culture of bacteria and yeast that ferment sugar water into a tangy drink called water kefir.

Water kefir grains are usually small, translucent, and crystal-like. They can sometimes be described as gelatinous or resemble cauliflower in structure. Their colours range from off-white to light brown, depending on the colour of the sugar and other ingredients you add during the primary fermentation.

Origin

The origins of water kefir grains are somewhat shrouded in mystery, but evidence suggests they may have originated in South and Central America. In Mexico, a traditional fermented beverage called tibicos was made from the sweetened juice of the prickly pear cactus. It's believed that these grains naturally form on the pads of Opuntia cacti as microbes feed off the sugars and water within the succulent plant.

Microbial composition

Water kefir grains are teeming with active cultures of bacteria and yeast. Most of these living species are probiotics, including strains like Lactobacillus brevis, Lactobacillus casei, Lactobacillus hordei, Streptococcus lactis, Leuconostoc mesenteroides, and Saccharomyces cerevisiae. 

This diverse microbial community within the water kefir grains drives the fermentation process. They consume the sugars in the water solution, producing byproducts such as carbon dioxide gas, lactic acid, and other organic acids. This process gives water kefir its characteristic effervescence and tangy flavour and provides it with its valuable probiotic benefits.

How to grow water kefir grains at home?

Kefir grains are living organisms, and like all living things, they thrive best in the right conditions. While they are typically quite active, sometimes they can be reluctant to grow and multiply. This can happen due to various factors, including improper culturing conditions and inadequate nutrition. Here's how you can grow water kefir grains and ensure they flourish well.

Ingredients and tools

• Kefir grains: A recommended grain-to-water ratio is 1:10, so 100 grams of kefir grains are needed for 1 litre of water.

• Filtered water: Filtered water should be free of chlorine and other harsh chemicals, which is essential for optimal grain health.

• Organic cane sugar: Sugar is the food for your grains. While organic cane sugar is preferred, you can also use coconut sugar. Use 50-100 grams of sugar for 1 litre of water.

• Molasses (optional): A pinch of molasses can provide essential nutrients.

• Sea salt (optional): Adds trace minerals that support microbial growth.

• Clean glass jar with a wide mouth: A glass jar resists contamination and allows easy cleaning.

• Cheesecloth or breathable lid: Use them to cover your jar, protecting it from contaminants while allowing airflow.

Step-by-step instructions:

1. Combine ingredients: Mix the sugar and water until dissolved, then add additional ingredients like molasses or sea salt. Introduce the kefir grains to the solution, maintaining the 1:10 ratio.

2. Cover and ferment: Cover the jar loosely with cheesecloth or a breathable lid. Place the jar in a warm, dark place (around 70-75°F or 21-24°C) away from direct sunlight and let it sit for 24-48 hours.

3. Monitor and adjust: Stir the mixture gently once or twice a day. Observe the fermentation process. You should notice the formation of air bubbles within 24-48 hours, indicating that the grains are actively fermenting. The kefir will also begin to develop a slightly tangy aroma.

4. Strain the liquid: After 24-48 hours, or when the desired level of fermentation is reached, carefully strain the kefir through a fine-mesh sieve or cheesecloth, separating the liquid from the grains.

5. Repeat the process: Discard the fermented liquid and repeat the process with fresh sugar water. Over time, your kefir grains will grow. After each fermentation cycle, strain the liquid to separate the grains. Reuse these grains to start a fresh batch with new sugar water, ensuring you repeat this process regularly to keep them healthy and active.

Great, your grains are growing strong! But what happens when you get a little carried away and end up with more than you need?

Effective storage methods for extra kefir grains

You've successfully brewed a batch of delicious water kefir, and now you have more grains than you need for your immediate brewing needs. What do you do with them? With excess kefir grains in hand, you must store them properly to ensure that they remain viable for future fermentation sessions:

• Keep in fresh sugar water: Store extra kefir grains in a clean glass jar filled with a small amount of fresh sugar water. Refrigerate the jar to slow down the fermentation process and prevent excessive growth.

• Feed the grains regularly: While refrigeration slows down activity, it's better to occasionally feed the stored grains with a small amount of fresh sugar water to keep them active and healthy. If you leave them in the refrigerator without feeding them for an extended period, they may become dormant and need more time to revive when you want to use them again. So, change the sugar water every 24-48 hours.

• Explore dehydration: Dehydration is an alternative method for storing kefir grains for longer periods. Rinse your grains thoroughly, then dry them on parchment paper at room temperature. Once completely dry, store the dehydrated grains in an airtight container in the refrigerator for up to six months or freeze them for up to a year. You can revive dehydrated grains by putting them in a sugar water solution for several hours before fermentation.

When you're ready to revive your stored grains, gradually activate them using smaller batches of sugar water. This helps the grains adjust and prevents over-fermentation, ensuring they are active and ready for your next brewing adventure.

Have you got some grains stored and ready to go? Perfect! Let's tackle what to do when things get tricky in your kefir-growing journey.

Addressing common challenges while growing water kefir grains

No matter how diligently you care for your kefir grains, there might be times when things don't go as planned. Growing water kefir grains can sometimes present unexpected challenges. Here are some common issues you might encounter and how to address them:

• Mushy grains: If your kefir grains become mushy or disintegrating, it might be due to an imbalanced mineral content or excessive sugar. You might need to adjust the mineral levels in your solution by adding a pinch of sea salt or moderate the sugar content. In some cases, mushy grains can be a sign of contamination. If you suspect contamination, discard the affected grains and start with a fresh batch.

• Slow growth: If your kefir grains seem to be growing slowly or not at all, factors like insufficient sugar, low temperatures, and old grains can be at play. Consider increasing sugar levels, adjusting ambient temperatures, or refreshing your grains with new ones from a reliable source.

• Dust on the surface: A thin layer of dust or sediment on the surface of the grains is normal. This is often a result of the fermentation process. However, excessive buildup may indicate contamination. Gently rinse the grains with clean, filtered water to remove any excess debris, but avoid frequent rinsing, as it can disrupt the microbiome.

• Presence of foam: The formation of some foam during fermentation is common and usually not a cause for concern. It's often a result of the release of carbon dioxide gas during fermentation. Normal foam levels are actually a good sign, but if it becomes excessive, move your jar to a cooler area to curb growth.

In addition to the above signs, be watchful for slimy textures or off smells, which may suggest temperature stress or contamination. Ensure your grains are in a stable, nutrient-rich setting with a balanced temperature. You can often remedy issues and foster a thriving batch of water kefir grains by staying attentive to these signs and making gradual adjustments.
