Product Description

ingredient handle mesh galon iced maker clean buffet tops magnet cannisters pickel safe washer

It's hard not to love all the great things Masontops can do to make your diet healthier without making it complicated or difficult. Or expensive. Just a small investment in these tools - which convert ordinary wide mouth mason jars into versatile superfood machines - quickly pays for itself many times over. Both for your budget and your health. Because Masontops is the leader in producing lids and accessories that empower you to ferment and sprout veggies (or simply store healthy foods and beverages) in mason jars. Like our sprouting and veggie fermenting lids, our kefir caps are thoughtfully designed to make each step along the way simple and low maintenance. Each set includes one blue and one green lid so you can tell them apart. And each lid is comprised of two pieces that snap together and each part provides a special function. The clear top part contains a measuring cup you can fill with your kefir starter grains. The bottom has a sieve top that keeps the grains in the jar when you're pouring out your finished kefir. Simply add milk or water to restart a ferment. And it so easy to get started. Measure and pour your grains in the jars and add liquid. Simply twist the assembled lid to the open position to allow air to circulate the fermentation process to begin. Depending on your ratios of liquid to grains and the temperature at which fermentation takes, you'll have your probiotic-rich beverage ready to drink in one to three days. Once it's ready, simply turn the cap to the closed position for storage or spill-proof handling. This set of two Kefir Caps ensures you can always have this healthy superfood on hand every day. Your tummy will thank you!

AWESOME!!
My first time making water kefir. Don’t know why others have struggled with this. This was soo easy. And these lids are awesome!! I added raisins to my kefir to let me know when it’s ready, they’ll raise to the top, then I moved my water kefir to 2 16oz jars and added raspberries to it, added a tight lid and let it sit out for 2-3 more days. Put in the fridge to get cold and tested it today and it was perfect!! Amazing raspberry soda!! I did grab some berry flavored stevia for my kiddos so they’d actually drink it and it is amazing. These lids are amazing!! Don’t think twice. Get them!

If you like your milk kefir to ferment for longer and it gets very thick, the lid holes are too small to strain the kefir from the kefir grains.

I was not too impressed. Was hoping to strain my kefir by tilting the jar (with the lid on) and pouring the kefir into the collecting jar. However, the grains would cause the lid to get clogged up, so I'd end up removing the lid after all, to help strain the liquid, the re-apply the lid and repeat. I was hoping not to have to open the lid at all. Ended up using a large strainer, it makes it for an easier and faster 'harvesting' of the kefir and starting another batch. Will give these lids away in hopes they might work for someone else.

I just started making kefir, and these lids are PERFECT! I use one on my fermenting jar, and one on the jar I keep in the fridge. Ingenious design for open or closed - keeps out any bugs that may be skulking around. Easy to clean and sturdy - I think these will last a very long time!

I'm not a fan of plastic generally. However, these clever lids fit the jars well, allowed in air while fermenting, and sealed when I was ready to refrigerate the kefir. They don't need to touch the milk. Another plus.

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

5.0 out of 5 stars Funktioniert prima und passen auf die Gläser von fairment!
Reviewed in Germany on August 10, 2024
Size: 2 lotsVerified Purchase
Ich habe mir ein Starterset für die Herstellung von Milchkefir bei "fairment" bestellt. Dabei war auch ein kleines Plastiksieb zum Abgießen des Kefirs dabei. Da der Kefir jedoch sehr dickflüssig ist und die Kefirknöllchen das Sieb natürlich sofort gefüllt habe, hat es trotz vorsichtigem Umrühren ewig gedauert, bis der Kefir durch das feine Sieb abgetropft ist. Das fand ich auf Dauer zu zeitaufwendig und ich suchte bei Amazon nach einer Alternative, die ich mit diesen Deckeln fand. Ich bin wirklich begeistert! Aufgrund der anderen Rezensionen war ich zunächst skeptisch, ob diese Deckel auf meine Gläser von fairment passen, habe aber zu meiner großen Freude festgestellt, dass diese sich einwandfrei auf meine Gläser schrauben lassen. Nun kann ich relativ schnell (natürlich läuft der Kefir trotzdem nicht wie Wasser durch die Deckel) den Kefir abgießen. Die Löcher sind zwar schon relativ klein, jedoch kommen dort trotzdem kleinste Stückchen durch, ob es Kefirknöllchen oder aber bei der Fermentation entstandene Kefirstückchen sind, weiß ich nicht. Aber das ist ok, da ich den Kefir nochmals abgieße, aber dafür dann das feine Plastiksieb benutze. Und damit habe ich dann einen wunderbar cremigen Kefir ohne kleine Stückchen. Ich kann diese Deckel also nur empfehlen! :o)
