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.


A nice gift

This Cold Brew filter works well. My wife has truly started to enjoy coffee at home instead of running out to Dunkin Donuts or Bigbucks early so she doesn't miss out. Amazed at the difference between Cold Brew and regular Iced Coffee...
(Double filtering makes a great improvement.)

Thanks to Grommet, I'm a hero!!!


Love this cold brew thing

I have ordered several items from The Grommet. I have always been pleased. I have this cold brew pair in my fridge at all times. One is brewing and one is holding last night's brew. Cold brew chocolate coffee is the best.


Perfect for ice coffee lovers!

The BRUW Story

BRUW | Cold Brew Mason Jar Kit

Mason Brew

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.
