They grab the first one they see, and get excited to start their kefir journey. After following the instructions carefully and waiting a few days for the fermentation process…disaster strikes! The holes are too small to strain rich, creamy milk. The grains get stuck at the top, leaving a big wasteful mess. That’s why we designed kefir lids that make the whole process clean and effective. Start saving money and have high quality food you can’t find at the supermarket. Our plastic strainer for kefir grains prevents clogs by offering lids with perfectly sized holes. The hole diameter keeps both milk and water grains in the jar, leaving you with perfectly strained liquid. Our lids have an adjustable silicone lid, allowing you to vary the amount of air exchange, while keeping critters out. All you need are some wide-mouth mason jars, a kefir starter culture and our lids and you'll have your very own water kefir starter kit. Tips and Tricks: - Use filtered water or spring water for best results. Chlorine or bottled water may have adverse effects on your kefir culture starter. - Let your milk sit at room temperature before adding the kefir grains. The longer you let it ferment, the thicker and sourer your kefir will be. Aren’t sure if you will like drinking kefir straight? You can use it in smoothies, batters, and other baked goods where milk, yogurt, or buttermilk is called for. Put your health first without breaking the bank. Start making your own nutritious kefir at home with our water kefir kit.

They make the messy process of Kefir so much cleaner and streamlined!

I don't have a lot of time like everybody else, yet I make water kefir which you have to change out every 2-3 days. This strainer/lid set saves a lot of time!! I put the strainer lid on the kefir with the grains and pour off the kefir into a quart mason jar, straining the grains. Then I refeed the kefir grains (1/4 c of Turbinado sugar dissolved in 3.5 - 3.75 cups of hot water, cooled, to refill the quart mason jar)... and put a coffee filter on it with a rubber band. I then add some kind of fruit to the kefir I just poured off (frozen strawberries work great when we don't have fresh raspberries or peaches... which flavor the most) until it is full and put the strainer lid on it with the cap. I let it set out on the counter overnight and then drink it over the next couple days (keeping it in the refrigerator until it is gone). The strainer keeps the fruit in until the kefir is gone. I eat the fruit at the end of the process. This kefir lid set works great to make the process quick and easy!! I've bought extra to give away as well.

It has a removable silicone ring and is shallow enough for easy cleaning w/ a brush. The strainer is harder plastic, the lid is thick-walled silicone w/ some flex. I'm skeptical that the grooves will be enough for air circulation, but I use disposable coffee filters + rubber band, and have a nutmilk strainer bag on the way to make a no bugs/dust barrier. I would not trust just the silicone lid to keep bugs out, even if they don't get in, they could be hanging out right on the surface, and if there's enough moisture and nutrients there they can lay eggs.The strainer holes seem a good size to strain kefir grains (which grow during normal use anyway), but even if it ends up being too large, this should still make for a good shaker top for wide mouth mason jars for powders. Or a strainer for larger material infusions.If the holes on these strainers are too big, you might try looking at "sprouting lids" that use finer metal or plastic mesh. Harder to clean though.

I used these lids for making kefir. They work pretty well but sometimes there was a leak.

I make a constant daily supply of water kefir. Having these lids has made the process easier and faster. They allow your first ferment to vent and keeps out everything you don't want getting in. The screen allows you to easily drain and rinse the grains without using an extra bowl/cup/strainer. Less dishes..less time . Only tip..when pouring liquid in over the screen make sure the stream is slow or tilt the jar or it will create an air lock and water will fill the top above the screen and not go through. (Yes I'm lazy and don't feel like taking it off every time due to arthritis in my wrists/hands) A++

The screen lid need to have smaller holes because not all kefir grains are larger than the holes in this lid. Kefir reproduces very small grains that grow so I have to strain twice. Smaller holes would be good but the design is satisfactory.

The holes are too big. The little baby kefir grains don’t get strained out so you you have to double strain through smaller mesh. The product itself is quality though.

Works well for thin kefir. So if using skim or 1% cows milk it is good. Possibly good for goats' milk as it is supposed to form a thinner kefir even with higher fat content.However for full fat milk it does not do well and top needs to be covered with fine mesh or the like to keep fruit flies and other small critters out.
