Works Okay

This works pretty well, but I've found that once I turn it over the coffee all settles on top of the mesh and pretty soon nothing is actually draining down to the bottom jar. I swirl it around but then sometimes grounds go down the tube. So I started opening it up and scooping out most of the grounds and then putting it back together and letting the mesh do the rest. So still works, but not quite as well as I'd hoped.
Doesn’t work as well as expected.

Still find it necessary to filter coffee one more time. Also find it difficult to get all grounds out of jar. Some always end up going down the drain (not good).
I’m so disappointed

I was so looking forward to this working! It did not. The coffee just will not filter through. I used coarse grounds and the straws stayed in place, but only about 1/2 inch filtered through. I’ve done well with other Grommet purchases but this was an expensive mistake. I cannot recommend it.
Works Great!

I was not sure if this would work, but it does and makes cold coffee that is not bitter. Mason jars are dishwasher safe, easy to replace if you drop one (like I did) and makes quite a bit of cold coffee. I use mine in the blender with ice, cream and sweeter to make a frothy frozen coffee drink.
Valued product.

Cold Brew Mason Jar Starter Pack

A filter and two mason jars are all you need to make cold brew at home. This full-fledged cold brew maker is super straightforward. The filter screws onto both jars, and sieves out the coffee grounds. The result? A fresh, smooth-tasting, cold-brewed coffee that’s less acidic and gentler on your tummy and teeth than coffee brewed with heat.


Make your very own cold brew coffee, easily. Put this cold brew coffee maker filter onto a wide-mouth mason jar.

It’s super straightforward. Let coffee grounds soak in a cold-water-filled mason jar for over twelve hours. When you’re ready to get your caffeine dose, twist the filter onto that jar with the straw side down. Then twist the second mason jar on top of the filter. Flip. Shake. And watch your cold brew filter through.

In case you’re uninitiated to cold brew, it’s smoother, less acidic, and it’s easier on your tummy (and teeth, too) than coffee brewed with heat. Less acidity also means you can better taste all the subtle flavors—like traces of chocolate, fruit, and nut inherent in different beans.

And even though grown-ups are the ones most likely to enjoy their coffee, this filter was invented by a teen. Max Feber was just 16 when he came up with the idea. It’s one you’ll be able to enjoy every day. more Their Story
