Can't tell you you too much as I bought it as a gift. But so far my friend is having fun with it as she works out the ratio of water to coffee.

These filters are such a great invention. The cold brew is great for supplementing the frozen coffee cubes I use to make coffee frappes'.

Love it!

I’ve been making cold brew laboriously for a year now and BRUW has made the process a breeze! I bought two 64 oz Mason jars to make my brew, and it works perfectly! As someone stated previously shaking the bottles once turned over to filter through definitely helps. I’d definitely give this as a gift again (did that too!). Yes, why didn’t I think of this!


Simple but Ingenious

So happy I bought this. It works as they claim it does. I have also come to learn how cold brew coffee it more health benefits when it is cold brewed than hot coffee. You can learn about that on YouTube.

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.
