Review: The Strainers Block up Too Easily - I bought the jars to go with the strainers thinking things were going to be simpler than using a handheld strainer; not so, the strainers block up really easily and you can't get the kefir out. When a handheld strainer blocks up, you use a spoon or spatula to move the grains around to get things flowing; you cannot do this from the inside of the jar, all the jars and strainer kits are left on the shelf unused.
Review: Me han gustado muchísimo, para el kéfir de agua son estupendos. Me gustan más que el kefirko, que también lo tengo. El filtro de Masontops está mejor diseñado, nunca se escapa nada. Son aptas para los botes de 86 mm, yo los compro en Koro o aquí mismo en desertcart. Ojo, hay que aprovechar cuando los bajan de precio, yo los he conseguido por 14,99.

## Questions & Answers

**Q: Does this work with milk kefir? All images are water kefir.**
A: I do use them on Milk Kefir jars sometimes, but the design lends itself to Water Kefir better as the holes are pretty small on top, and thicker kefir will not strain as well. But the top is functional otherwise.

**Q: Does anyone actually strain milk kefir through the part with holes and then add more milk? I did not realize these were really for water kefir.**
A: I did not realize they were for water either. Do not buy for milk kefir as you will waste a lot.

**Q: Will I need to burp water Kefir with these tops?**
A: Hi there - Thank you for your helpful question! No, with our Kefir Caps, burping is not required. Thanks again!

**Q: Will this fit my 32 oz mason jar for making milk kefir?**
A: Hi there - Thank you for your helpful question. Our Kefir Caps are designed specifically for WIDE mouth mason jars. In the North America, standard-size Mason jars are made of soda-lime glass and come in two sizes: regular mouth, 2 3⁄8 in (60 mm) inner and 2 3⁄4 in (70 mm) outer diameter, and wide mouth, 3 in (76 mm) inner and 3 3⁄8 in (86 mm) outer diameter, versions.

If you 32 oz mason jar is a wide mouth jar ( 3 3⁄8 in (86 mm) outer diameter) then yes the Kefir Caps will fit.

### ⭐⭐⭐⭐⭐ Review
*by M***A on 26 July 2019*

Great design. Very well made, sturdy, dishwasher safe, easy to use. Fits perfectly on wide mouth mason jar. Easy to burp, or to open/close the air flow depending on what stage of fermentation you’re in. Would be perfect for water kefir, goat milk kefir, or lower-fat cow’s milk kefir. Higher fat kefir is too thick for the size of the mesh.
