I am completely new to kefir making.So far I have made 2 batches and have been thrilled, but just want to check something. I was gifted the kefir grains a few days ago. I ran cold water over them in a colander(my friend suggested that, because the grains had been in a car all day while she was at work), then i put them in a glass quart jar and added maybe 2-3 cups whole milk, covered w/ a cloth (fastened with a rubber band). After the mixture had thickened at room temp, 2 days, I poured the kefir through a plastic colander and removed the grains back to the same jar, added milk and am repeating. My question is that the mixture that goes through the colander is kind of buttermilk thick, and is grainy. I will always be adding fruit to it for a breakfast drink and so it has all come together once blenderized. But is that graininess what i should be seeing, or have i not let it thicken long enough? The 2 kefir batches i have made have tasted tart but not overly tart.yummola. this is aLOT easier than yoghurt (when i made it 40 yrs ago!) thx for your help.
