If you want to take a break without destroying your grains or wasting milk, you’ll need to figure out how to freeze milk kefir grains. You can freeze milk with short-term storage and long-term storage.
Short-Term Storage
Before putting your grains in the fridge-freezer, ensure they’ve been actively cultivating for at least 3 to 4 weeks. Let’s start with the following steps:
- Cover the grains with fresh milk until they are thoroughly coated. Use extra milk during longer breaks to keep them adequately fed.
- Refrigerate the container with a tight-fitting lid. The milk kefir grains should be safe and nutritious for around three weeks.
- To resurrect them, strain them from the milk. Then, as standard, ferment them in a jar of fresh milk.
Pro Tips:
- Switching back and forth between room temperature ferments and the fridge can cause long-term problems.
- The grains can have that characteristic fridge odor after a week or two, and then it becomes more unbalanced from there.
- If you do the ferment multiple times a month, the ferment will likely vary in consistency or flavor.
- Also, if you keep the grains in the fridge for more than a month, they may develop problems.
- If you want to take breaks more frequently than once a month, use the freezing technique or a mix of the fridge and freezer methods.

Why are Kefir Grains Disappearing or not multiplying?
Although milk kefir grains frequently increase, no one can promise that they will multiply in the same way in every environment.
Factors all play a role in the final product’s growth includes:
- quality of milk
- culturing environment
- room temperature
- climatic conditions
- hygiene, glass jar shape
- milk fat & lactose content
- the proportion of kefir grains and milk
- quantity of milk used for each fermentation
The major disadvantage of tiny kefir grains is the difficulty in removing kefir seeds from fermented milk. Separating the small particles from the protein and fat in milk is tough.
Furthermore, the kefir particle size reduces, allowing smaller particles to flow through the filter. So, the kefir particles will vanish in consecutive batches.
Can I Rinse My Kefir Grains?
This is something you should never, ever do. It harms them and removes the beneficial bacteria that allows them to grow.
After washing, they frequently die, stop reproducing, or fail to produce good kefir. Some kefir grains may survive, but they slow them down and harm them.
You should use fresh milk to rinse them. You may also feed them a prebiotic like Prebio Plus, which nourishes and strengthens them while making your kefir creamier, especially if it separates.
