Congratulations, and welcome to the world of kefir!!! The kind of milk you use is up to you. The grains I received were from a gal who's family ran a large dairy in Eastern Kansas, so they were grains that had only been used in raw milk. Since I do home food storage (I haven't purchased liquid commercial milk from a grocery store since 1981), I use reconstituted powdered milk - and have all the years I've made kefir (over a decade). No transition period.... Occasionally I'll have some 1/2 & 1/2 or whipping cream on hand and I'll add a little of it to the milk for a richer/thicker curd. I can also get a thicker curd by using more milk powder, but I think the grains "like" the additional fat provided by the 1/2 & 1/2 and whipping cream occasionally. I also use reconstituted powdered coconut milk for coconut kefir (you can also used canned coconut milk or make your own with unsweetened coconut and water - blended and strained). Occasionally when I get extra grains I'll make a batch or two with cider or 100% grape juice - but the grains don't thrive more than a few non-milk batches. I've also made it with raw goats milk, but not very often. It's not budget-friendly. Kefir can have a cleansing effect and your body will let you know how much is "enough", or too much. We only consume 2 servings of dairy each day, and the morning kefir counts as one of them. I use it in a smoothie-type mixture every morning. I also use it as a substitute for buttermilk in cooking/baking. Drain the curd and it's my substitute for plain yogurt, cream cheese, and sour cream - as needed. Where you will notice a difference in taste is when the temperature fluctuates. I personally prefer the more mild-tasting kefir fermented in cool winter temperatures (ambient temperature in our kitchen doesn't usually get above 64-degrees F in the winter), compared to the more sour/tart kefir made when the temperature is much warmer, but I use it all year and make it about every 4-5 days. It your kefir gets "gritty", that means the temperature is too warm for fermenting. The warmer the temperature, the faster it ferments. Sometimes in as little as 9-12-hours. My favorite is coconut milk kefir, but I only make it once a month, or so. It makes a nice add-in to orange or pineapple/orange juice, or used in desserts, and great topped with granola for breakfast or a snack. -Grainlady

marita...my understanding of what you should receive when you purchase the grains online is a dried product that takes approx 7 days to fully rejuvenate. There are exact inst. on the net for how to reconstitute dry grains. I haven't heard of anyone sending out wet/slime grains :) There are no grains per se in my kefir since the weather has gotten cooler. But...today just to help out with your research I let a jar of kefir set out in a warmer place and it has indeed formed a large mass of grains floating on a bunch of clear whey. So it is indeed temp related. I had another jar of fresh milk and 2 tsp of grains sitting in a cool place in the kitchen since this AM and it has become my usual jar of soft yogurty type stuff with no separation and it is ready to go into the fridge to be used in a smoothy in the AM. All temp and time related. As I said...at cool temps it is highly unlikely that you are going to get any distinct grains/curds. It will all be soft cheesy stuff. If I were to put mine in a strainer most of it would stay in the strainer just as yogurt does. When it was hotter weather it drained out a lot of white and clear together and left drier distinct curds...again it is all temp related. I would not give up on what you have. It tastes pleasant...it smells pleasant. When the temps change so will your kefir. I hope you cont. to enjoy. I have now shared my grains and they are living in Montgomery AL and Lexington VA !! It is a wondrous process. c Oh..ps about resting the grains. I take 2 tsp every AM of the current kefir that I am going to eat and place it in a jar of fresh cold 2 % milk and leave it in a cool place for 12 hrs and then place it in the fridge over night...Next AM take out 2 tsp and place in cold milk and leave out....then in fridge and repeat. As far as rest...well they are in new milk every day and they are at a pretty cool temp and the source has been in the fridge all night fully fermented but very cool and waiting /resting. As my grains seem so happy I am not going to change anything. If your grains are happy and taste good I would say " yes" to the process you are following.

Water kefir notes Probiotics, think of yogurt but not dairy. So it's very good for you like any other fermented type food, sauerkraut, miso, kimchi, etc, 2. Easy to make, won't fail or go bad. 3. Put them in soup, smoothies, etc. helps with pets digestion as well. cause it's sugar water, so anything you want to cook with that calls for liquid and sugar are ok. Experiment. 4. Make a beauty mask out fit 5. Add it with any flavor of juice concentrate, bottle it you got Italian soda! But the fizz last much longer cause it keep producing it. Ball quart jar is perfect. 1/4 cup -1/3 cup sugar. 1. Fancy version: mineral water, organic brown sugar, a touch of molasses, with organic lemon slice/ ginger / raisin, etc 2. Daily version, fridge filtered water or tap water sit 24 hours, regular brown sugar, that's it. Cover with a piece of paper towel tight with rubber band 3. When it double, filter the grains out and rinse it with filtered water, repeat process. Put water kefir in a glass bottle, with a screw-on lid, let it sit on the counter for 24 hours, then flavor it ( individual AW plastic bottle root beer is perfect, it's the strongest flavor and the color matched! that's what my husband bring to work everyday) put It keeps a longtime. Next time when you have children over, instead of giving them store bought soda, have them try this instead.

Updating my kefir experimentation results: I made a kefir cheese ball, by hanging the curds is a bag until solid, then adding dried onion flakes, red pepper flakes, granulated garlic, basil flakes, salt, pepper, and a little sugar to try to balance the sourness of the cheese. I still didn't care for it without the butter and cream cheese, but my son loved it with crackers, so I sent it home with him. If I have extra cheese, I'll save it for his visits. I made sugar cookies today, using a drop cooky recipe that I've been using for many years, but I substituted 1/2 cup kefir cheese for 1/4 cup of the butter, and left out 1 Tbs of the milk. Since the cheese was a little 'curdled' and very sour, I added a couple of Tbs. of corn syrup and substituted 1/4 tsp of baking soda for 1/4 tsp. of the baking powder, because of the lactic acid. Oh my, are they good!
