    Kefir has been called the "champagne of dairy products." Our kefir produces a rich, creamy drink with a bubbly effervescence which may be sweetened with honey or maple syrup to produce a refreshing and nutritious dairy treat. This culture can be used with cow, soy or goat milk and may be re-cultured.

    This culture can be re-cultured but it is a complex culture (many different cultures) and is very difficult to get consistent results without good temps and time controls on the ripening.

    CULTURE INCLUDES: l. cremoris, l. plantarum, s. lactis, s. cremoris, s. diacelilactis, saccharomyces kefir, skim milk powder, ascorbic acid

    ALLERGEN WARNING: This product is manufactured in a facility that manipulates products that contain wheat, soy, eggs, milk and fish (including shrimps).

    YIELD: One packet will culture 1 gallon of milk.

    DIRECTIONS: Heat 1 gal. of pasteurized milk to 86ºF. Add and mix in 1 packet. Cover and let set at room temperature undisturbed for 12 hours or until thickend to desired consistency. Refrigerate.

    STORAGE: Keep packages in the freezer, they will last up to 2 years.

    DISCOUNTS: If you really love these you can buy 12 or more 2-packs and you will receive our price break of $3.00 for each 2-pack.

    NOTE: This is very simple to make using our Yogotherm (E69).

    Kefir

    What is Kefir:
    Kefir is not so familiar to folks in America but in many traditional cultures fermented milk products such as Kefir and Yogurt have been prepared at home for centuries. Culturing fresh milk into Kefir makes the nutritional factors in the milk, such as vitamins and minerals, extremely bio-available so your body can easily absorb and digest them.
    Kefir contains a complex culture of many healthy, hearty bacterial strains, passed down from family to family for centuries.

    Kefir can be made as a mild and thick textured milk for drinking or making into "Smoothies" or other delicious beverages as well as a more tangy thicker version that can be drained as a cheese wonderful treat similar to "Greek style" drained yogurt or even molded into a cheese and ripened further for several days or weeks. Some folks have even used the Kefir culture with rennet in making a Kefir cheese, which will use not only the lactose working bacteria but also the yeast and other Kefir components.

    Why Make Kefir:
    So often we get comments from folks who would like to make yogurt from raw milk but do not want to increase the temperature high enough to damage the natural milk bacteria and enzymes following the directions on our Yogurt page.
    Kefir is the solution! Make Kefir from this milk instead of Yogurt.
    In making Kefir nothing really gets heated higher than the temperature of mama cow. This means that all of the bacteria and enzymes you have spent so much time to get in your raw milk will not be destroyed in the final Kefir product.

    Comparing Kefir to Yogurt:
    In addition to lactic fermentation Kefir also undergoes alcoholic fermentation caused by the presence of yeast, which yields this sourish, yeasty, sparkling, refreshing end product. Also as mentioned above Yogurt production involves temperatures that destroy the natural enzymes and bacteria of raw milk whereas Kefir temperatures are low enough to preserve these.

    Kefir from grains or "Direct Set" culture:
    In making Kefir you have 2 options to consider for your first batch of Kefir. Traditionally people would save the granular bits that formed at the bottom of the Kefir jar to begin a new batch with fresh milk. Todays option is to use special culture powders that will always guarantee the same degree of activity. Since we are most interested in our customers having consistent results from batch to batch we have chosen to provide this "Direct Set".

    • The Kefir grains may produce a more complex product but they need to be re-cultured in a timely manner to keep the Kefir going. This does not always fit into peoples schedules in our modern times
    • Our Direct set C45 Kefir culture and C46 Re culturable Kefir culturecan made at any time from the culture packs and yet can be re-cultured if desired for many generations. 

    How to make Kefir:
    Making Kefir is actually easier than making yogurt. In making traditional yogurt a step is needed to release the whey proteins for a thick textured Yogurt by increasing temperature to 185ºF and holding it there for 10 to 20 minutes (from our Yogurt page). This will destroy all of the natural enzymes and bacteria found in raw milk since this is in excess of even normal pasteurization temperature.
    When making Kefir

    • One Gallon of milk is only mildly heated (86ºF) preserving these enzymes and bacteria. Some folks suggest doing this at room temp but we find that 86F is the optimum temp to start the cultures activity. It can then be allowed to cool to room temp as the milk ripens in the final step.
    • Transfer the milk to a sanitized container then add 1 pack of our culture (C45 Kefir culture) or C46 Re culturable Kefir and stir well into the warm milk.
    • This is then covered allowed to ripen at room temperature (68º-72ºF) for 8 to 18 hours or more depending on the character you would like in your Kefir.
      Longer time and warmer temps will make a more tangy tasting Kefir.
      With each batch you make, adjust the time until you get it just the way you like it.
    • Time and temperature are the two control factors that determine the thickness and taste of your Kefir. In the warmer months Kefir may be ready to drink in 18 hours. If allowed too ripen too long at higher room temperature, it will become acidic, thick, and eventually the whey will begin to separate. If your Kefir is "lumpy" and too sour, it has ripened too long or at too high a temperature. It should be creamy and perhaps a little thicker than milk. At this point, shake it well and place the Kefir into your refrigerator. It will thicken a little more since the culture will continue to do its work, but at a much slower pace.
    The following photographs show some of the variations of Kefir ripening times that you can experiment with to find the perfect style for you and your family.
    Here I have set up a ripening environment in a temp controlled (aquarium heater) water bath to observe the character of several ripening times and their final textures and flavors. I have used a pH meter to monitor the progress of the cultures along the way. The right hand photograph show 2 of the final products at 8 hrs and 48 hour ripening times.
    This creamy Kefir has been ripened for 8 hours. This is a Kefir ripened for 48 hours developing a definite curd which I have ladled into a draining cloth.
    After 6 hours of draining 1/3 of the Kefir volume has drained off as a very tangy whey. This whey can be used as a nice cool beverage or in cooking instead of water for soups, stews, etc. The final drained Kefir is now ready to chill and eat

    Kefir as you like it:
    The final Kefir can be more or less acidic as you might prefer it by simply increasing or decreasing the time you allow it to ripen. 8 hours will produce a mild acid flavor and a smooth milky consistency where a 12 hour or longer ripening period will produce a thicker and tangier flavor.
    In making test batches of Kefir here I have allowed the milk to ripen for different time periods ranging from 6 to 48 hours with the results shown below.

    • At 6 hours this is a mild fermented milk that flows just a bit thicker than unfermented milk but contains all of the good things in the Kefir (pH is greater than 5.3).
    • At 12 hours the milk develops a nice tang from the culture activity and has become much thicker (pH of 5.1 to 4.7).
    • At 24 to 48 hours, the milk becomes much thicker and forms a good soft curd. The flavor has a wonderfully refreshing acidity (pH is now as low as 4.3-4.5).

    Kefir Cheese:
    This cheese follows in the path of Lebnah, a drained yogurt cheese.
    With the longer ripened, more acidic kefir above, the curd becomes firm enough to drain through a double layer of butter muslin. This will allow about 1/3 of the volume to drain off as whey and the curd now becomes a very thick curd which can be used with fruit similar to the greek styled drained yogurt. I like this drained Kefir better because of its more complex flavor.
    Another approach is to drain the Kefir to the point that the thick curds can be rolled into small balls and allowed to air dry a bit and form a dry rind (usually requiring air movement such as a small fan). When dry enough these can even be mixed with olive oil and herbs for a real treat.

    Trouble-Shooting:
    If the milk does not thicken into kefir or the kefir turns out too thin here are a few point to consider to find out why:
    1) the milk may have gotten too cool during the ripening period,
    2) the milk may have cooled down too much before you added the culture,
    3) you may have not put enough starter from the previous kefir batch in the milk (usually 1 to 2 tablespoons of the previous culture per quart of milk will be adequate),
    4) your starter may have been too old and no longer active (the kefir culture is usually good for 7 to 10 days, sometimes longer),
    5) you may have accidentally overheated the milk together with the culture, which kills the culture, or
    6) everything may be fine except that you may need to let the milk culture longer to be a firmer texture (12 to 24 hours).

    Tip from a customer!!
    "Just a tip for long incubations requiring temperatures of 86-100F: If your oven has a Proofer setting, you can use that. If not, you can use a poor mans proofer, in which you boil 2 cups of water in a pot or large glass measuring cup, cover it and put it in the oven for 15 minutes while you heat your milk. Remove the pot and put in the cultured milk. The oven will stay a balmy 92-96F for hours!!"

    Jim, our tech man, had this to add: There are many other ways to do this as well. Mine is to use an insulated cooler with bottles of warm water to hold the temps. This will keep your oven open for use and you can move the cooler out of the way.

    FREQUENTLY ASKED QUESTIONS:

    Q. I just purchased a packet of the c45 kefir culture that came from your site. I was curious to know if I could make a smaller batch of kefir using the packets...this is my first time making kefir and I am probably the only person in my house who will be consuming it.

    Do you know if anyone has had success doing a half or quarter batch?

    A. You should be able to approximate 1/2 of a pack but the other half would need to be used up within a month once opened.

    When i made the kefir, I let it sit for 24 hours instead of twelve- it took that long for it to reach that yogurt drink consistency, and it was delicious! My toddler drank it plain, but he likes plain yogurt. I found it perfect for savory applications- a delicious cucumber onion salad with mint, salt, lemon juice and olive oil, for instance. I'm used to making yogurt without a yogurt maker, so not having to try to maintain the perfect temperature made kefir making very enjoyable. I'm going to try the reculturable one next. Thanks Ricki!
