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: Very useful - Very handy and useful in making Kefir. Fits standard Mason jar securly and with rubber seal inside, there are no leaks or spills. The lid opens to either remove completely (when pouring) or when making kefir - giving the required air without allowing dust or any contaminant into the jar. Pouring from the jar is very easy, by removing the opaque cap - and it strains at the same time. Very easy to clean Highly recommend ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RDXY2CV | | Brand | Masontops | | Brand Name | Masontops | | Closure Type | Twist Lock | | Colour | White | | Customer Reviews | 4.4 out of 5 stars 2,634 Reviews | | Is the item dishwasher safe? | Yes | | Is the item microwaveable? | Yes | | Item Dimensions L x W | 9.1L x 9.1W Centimeters | | Item Weight | 159 g | | Manufacturer Part Number | KC2WGB | | Model Number | KC2WGB | | Number of Pieces | 2 | | Product Dimensions | 9.1L x 9.1W Centimeters | | Product Style | Classic | | Shape | Round | | Style | Classic | | UPC | 829188000899 | ## Product Details - **Brand:** Masontops - **Colour:** White - **Item Weight:** 159 g - **Product Dimensions:** 9.1L x 9.1W Centimeters - **Style:** Classic ## Images ![Masontops Kefir Caps - Wide Mouth Mason Jar Lids - Live Culture Grains Strainer - Home Fermentation Starter Kit - 2 Pack - Image 1](https://m.media-amazon.com/images/I/81DUOG40HXL.jpg) ![Masontops Kefir Caps - Wide Mouth Mason Jar Lids - Live Culture Grains Strainer - Home Fermentation Starter Kit - 2 Pack - Image 2](https://m.media-amazon.com/images/I/81vHQeYHwAL.jpg) ![Masontops Kefir Caps - Wide Mouth Mason Jar Lids - Live Culture Grains Strainer - Home Fermentation Starter Kit - 2 Pack - Image 3](https://m.media-amazon.com/images/I/81ZG+WfpeJL.jpg) ![Masontops Kefir Caps - Wide Mouth Mason Jar Lids - Live Culture Grains Strainer - Home Fermentation Starter Kit - 2 Pack - Image 4](https://m.media-amazon.com/images/I/819zXycRacL.jpg) ![Masontops Kefir Caps - Wide Mouth Mason Jar Lids - Live Culture Grains Strainer - Home Fermentation Starter Kit - 2 Pack - Image 5](https://m.media-amazon.com/images/I/81nyzGO3slL.jpg) ## 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. ## Customer Reviews ### ⭐ The Strainers Block up Too Easily *by M***E on 16 December 2021* 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. ### ⭐⭐⭐⭐⭐ Very useful *by M***L on 9 April 2024* Very handy and useful in making Kefir. Fits standard Mason jar securly and with rubber seal inside, there are no leaks or spills. The lid opens to either remove completely (when pouring) or when making kefir - giving the required air without allowing dust or any contaminant into the jar. Pouring from the jar is very easy, by removing the opaque cap - and it strains at the same time. Very easy to clean Highly recommend ### ⭐⭐⭐⭐⭐ Perfectos *by M***A on 4 July 2023* 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 Amazon. Ojo, hay que aprovechar cuando los bajan de precio, yo los he conseguido por 14,99. ## Frequently Bought Together - Masontops kefir lid mason jar lids wide mouth mason jar lids living culture grain drainer starter kit for home fermentation 2 packs - 1 TBSP Milk Kefir Grains and eBook "Milk Kefir Unleashed by Thomas Egbert" - Fresh Live Active Probiotic Starter Cultures - Fusion Teas - Cultures for Health Kefir Starter Culture | 4 Packets Freeze Dried Starter Powder | Make Kefir with Milk, Water, or Juice | Re-Culture Kefir Probiotic Drinks 2-7x Each | Cultures in Less Than a Day --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/305402172-masontops-kefir-caps-wide-mouth-mason-jar-lids-live-culture](https://www.desertcart.vn/products/305402172-masontops-kefir-caps-wide-mouth-mason-jar-lids-live-culture) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
