RINSING KEFIR GRAINS
You may find discrepancy regarding the rinsing of kefir grains between each milk change. My understanding is, traditional kefir grains were not rinsed between milk changes by the tribes-people of Northern Caucasus, where kefir originated. In fact, research suggests rinsing kefir grains actually interferes with the balance or the rhythm of kefir grain's microflora [1].
Recent research suggests not to rinse kefir grains between each milk change, due to the arrangement of the microflora over the surface of the grains. Most of this research was performed in the former USSR [2, 3].
As long as utensils are kept clean and ingredients are fresh and of the highest quality, rinsing kefir grains is not necessary. Rinsing kefir grains came about after kefir grains and kefir were introduced to the rest of the world, and over recent years, possibly due to concerns of weed microorganisms settling on the grains. The very viability and properties of the microflora of kefir grains, and possibly the grains themselves, seem effective to naturally inhibit or antagonize the growth of weed organisms. I am able to exploit this very nature of kefir, by implementing kefir as a natural preservative for preserving fresh foods in solutions as little as 10% kefir or kefir-whey, with exceptionally good results.
I also try to leave intact as much of the water-soluble polysaccharide [kefiran] produced by the grain's microflora as possible. This may then be dissolved and found in greater amounts in the finished kefir. Rinsing the grains between each milk change may inhibit or decrease the amount of kefiran. In Caucasus the grains were continuously left in leather bags, and not all the kefir was removed at any one time. Amounts of previous kefir would be present [buffer], when adding fresh milk to the bag. The is known as the Continuous fermentation. Doing so, the pH of the added milk is reduced [acidified], and a hastened fermentation that follows quickly reduces the pH even further, which is most favourable for inhibiting weed organisms.
Because of the fashion in which the microbes are arranged over the surface of the grains, rinsing the grains with water or with fresh milk removes many of the wanted microbes, in effect, lowering counts of essential organisms of kefir. This should in fact encourage the growth of weed organisms due to less competition.
After researching, I no longer rinse my kefir grains, as I used to do many years ago, because I was instructed to do so by the person who gave me the first amounts of kefir grains in 1978. However, on the rare occasion I fast my kefir grains in sterile water only, for one day. I find this method is effective in keeping kefir grains clean and healthy. The water-based compound solution strained from water-fasted kefir grains [which I refer to as Kefiraride], has many applications, including the preparation of natural cosmetics, helping to control thrush [C. albicans infection], just to mention a few.
Please go to Dom's Kefir FAQ in-site for tips and recipes for Kefiraride [see FAQ 18].

สงสัยจะไม่สมควรล้างจริงๆนะ -*- แต่ควรใช้น้ำที่ต้มเดือด(ผ่านการฆ่าเชื้อ)
หมายเหตุ อุปกรณ์และ kefir ของเราจะต้องสะอาดด้วย และเก็บอย่างสะอาด รวมไปถึง kefir นั้นจะต้องแข็งแรงนะคะ แต่จาก คห. 81 ในสัปดาห์หนึ่งก็ควรล้างสักครั้งนะคะ***
ติดล้างซะด้วยสิ
