Q. What ingredients go into creating milk kefir grains?
A.Cultures for Health milk kefir grains are grown using only organic milk.
Q.What is the difference between kefir grains and powdered kefir starter culture?
A.There are three primary differences between milk kefir grains and powdered kefir starter:
- Milk kefir grains have alarger number of probioticsthan the powdered starter culture.
- With proper care, kefir grains can beused indefinitely to make kefir. Powdered starter culture can be reused for a number of batches, but will eventually stop culturing.
- Powdered kefir starter culture has a smaller initial investment cost than do kefir grains; however, you will need to continue to purchase new culture if you wish to make kefir beyond a few batches.
Q. What strains of yeast and bacteria does milk kefir contain?
A.While the probiotics can vary with each batch made with milk kefir grains, alist of bacteria and yeasts generally found in Milk Kefir Grains can be found in.
For our powdered kefir starter cultures, a list of ingredients can be found on each product page.

Q. Are milk kefir grains reusable? Is the powdered kefir starter culture reusable?
A.Yes, milk kefir grains are reusable. Once a batch of milk kefir has finished culturing, simply remove the milk kefir grains and place them in fresh milk. The powdered kefir starter culture is also reusable several times.Simply follow the instructions forMaking Kefir with a Direct-Set Starter Culture.
Q. How long do dairy kefir grains last? How long does the powdered kefir starter culture last?
A.If cared for properly, milk kefir grains have anunlimited life spanand can be used repeatedly to make kefir.
Kefir made with a direct-set style starter culture can often be re-cultured from2 to 7 times. The exact number of successive batches will depend on the freshness of the kefir and hygienic practices employed.

If you are not using kefir grains, please see our detailedinstructions for making milk kefir using the kefir starter culture.
Q. How long does it take for the milk kefir grains to rehydrate and begin making kefir?
A.The rehydration process may take up to 7 days. Be sure to follow theInstructions for Activating Milk Kefir Grains. Within the first few days, an overgrowth of yeast or a layer of froth or foam may form on the surface of the milk. This is normal as is the smell of fresh yeast.
Q. What do I do with the milk used to rehydrate the kefir grains?
A.The milk used each day to rehydrate the kefir grains can be consumed orused for cookingprovided it looks, smells and tastes okay. Alternatively, you can discard any milk used during rehydration.
Q. How will I know when the milk kefir grains are making kefir?
A.Once the milk starts to thicken (similar to the consistency of cultured buttermilk or heavy cream) and the aroma is pleasant, the kefir grains are making kefir.
Q. How long does it take to make milk kefir?
A.Kefir generally takes 12 to 24 hours to form. The exact amount of time will vary depending on environmental factors, the most important of which is temperature.
Cold temperatures slow the fermentation process (and it can be all but stopped byplacing the grains in milk in the refrigerator).
Heat speeds the process so kefir will form more quickly in a warm area and will be more likely to over-culture.
Allowing the kefir grains to remain in milk longer than 48 hours risks starving the kefir grains and potentially damaging them.
Q. My house is colder than 68°F, how can I culture milk kefir?
A.Many homes maintain temperatures that are cooler, especially in the winter. For tips on keeping things within the proper temperature range, see our article,Cold Weather Care for Starter Cultures.
Q. Do Ineed to stir the kefir during the culturing process?
A.You can stir the kefir while it's culturing but it's not necessary.
Q. How will Iknow if I've successfully made kefir? How do Iknow if I shouldn't drink it?
A.The milk will thicken and can have a tangy or sour aroma and flavor. We always recommend that you refrain from consuming anything that looks, smells, or tastes unpleasant.
CARING FOR YOUR KEFIR GRAINS
Q. Do I need to wash the jar/container between batches of kefir?
A.We recommend using a clean container for each batch of milk kefir.
Q. Can I use a metal strainer with my kefir grains?
A.Whileplasticis preferred, stainless steel is acceptable.Avoid all other types of metalwhen working with kefir grains.
Q. What is the recommended ratio of grains to milk for culturing with milk kefir grains?
A.We recommend using1-2 teaspoons grains for culturing up to 4 cups of milk.Some customers have reported being able to culture 4 cups of milk with as little as½ teaspoon of grains. Adjust the amount of grains to avoid over-culturing and to impart the best flavor.
Extra grains can be used to culture another jar of kefir, shared with friends, eaten, blended into smoothies, ordried and storedin some powdered milk in a sealed container in the fridge as backup.
Q. Do I need to rinse the grains off between batches?
A.No. There is no need to rinse the grains unless they stop making kefir effectively (which can sometimes be attributed to a buildup of yeast on the grains). If it becomes necessary to rinse the grains, use filtered water if possible to avoid chemical exposure.
Q. Do Ineed to make a full quart of kefir each time or can Imake smaller batches?
A.Making a full quart is not required. Many of our customers find that making 1-pint batches better meets their needs. To learn more about how to slow down your milk kefir or make smaller batches, read our tutorialHow to Slow Down Milk Kefir + Make Smaller Batches.
Q. Can I make kefir only once a week and keep the kefir grains in the refrigerator on the other days?
A.We caution against keeping your kefir grains in the refrigerator on a regular basis. Cold temperatures slow the kefir grains down putting them into a state of hibernation. It can be very hard on kefir grains to regularly be put into and then come out of a state of hibernation. It can disrupt the yeast/bacteria balance and may also make the kefir grains less efficient and reliable.
If caring for kefir grains every day or every other day isn't an option, consider using a powderedkefir starter culturerather than kefir grains to make kefir. This product requires significantly less maintenance than kefir grains.
Q. Will milk kefir grains multiply?
A.Milk kefir grains are known to multiply, but at times they are reluctant to do so. Even if they do not multiply, with proper care, kefir grains can be used repeatedly to brew milk kefir. Generally kefir grains take6 to 8 weeks following rehydration to begin multiplying.Learn more aboutEncouraging Milk Kefir Grains to Multiply.
Q. Will kefir culture in a dark cupboard or in a window (exposed to light)?
A.Kefir doesn't require light to culture properly, so a dark cupboard is fine, as is a lighted room. Do not expose culturing kefir to direct sunlight.
Q. If I’m making other cultured foods (yogurt, sourdough, kombucha, etc.), how far apart do I need to keep the kefir culture?
A.We suggest a distance of at least 4 feet between cultures. When being stored in the refrigerator with tight-fitting lids, there is no need to keep distance between them.
USING KEFIR GRAINS IN DIFFERENT MILKS

Q. Can I use UHT(ultra-high temperature aka ultra-pasteurized) milk to make milk kefir?
A.Milk that is “too clean,” such as ultra-pasteurized/UHT milk, or milk that has been heated by microwave, may be too sterile for the milk kefir grains to use as nourishment.
Q. Can Iuse non-hom*ogenized milk to make kefir?
A.Yes. Non-hom*ogenized milk makes wonderful kefir. The cream will rise to the top of the kefir just as it does with the milk Once cultured, the top layer of the kefir will be more yellow in color and very thick, while the skim milk portion at the bottom will be cultured but thinner than hom*ogenized whole milk kefir.
Q. Can milk kefir grains be used with raw milk?
