Good cold brew maker…
Style: 1pcs 64oz black
Very much into cold brew now for several years and wanted to give this type of maker a try.
Since I wasn’t sure if I would like it or not, I decided to go with the cheapest one and it was available with same-day delivery to boot!
It is a winner! It is simple to use. Just fill the filter about 2/3 of the way full with coarse ground coffee and fill with water. You can let it sit in the refrigerator or on your countertop at room temperature. I think room temperature brews a little bit quicker.
A very big plus is the metal mesh filter. It cleans and rinses off very easily. The lid and jar seem to be of excellent quality.
I purchased the 64 ounce because I love my cold brew, but it is a little bit bulky and heavy for us senior citizens.

Perfect Cold Brew Coffee
Style: 1pcs 64oz black
Works like a charm. The mesh filter actually prevents grounds from collecting in the coffee and is easy to clean. Don’t use fine, ground coffee but slightly grounded beans for a robust flavor. You can’t beat the price of this simple, uncomplicated brewer.

SO easy & saving me $$
Style: 1pcs 64oz black
This is a great cold brew coffer maker. Basic design which makes it so easy to use. I add 1/2 cup of quality ground coffee & just set it in the fridge for 48 hours. It's delicious, convenient & affordable. Saves me quite a bit of money on this type of drink from a coffee shop. It was referred to me & I refer it to others. Treat yourself!

I LOVE this!
Style: 1pcs 64oz green
I LOVE this! I've been spending too much $ for too many years on expensive cold brew coffee. Even from the grocery stores..with this I get really rich flavor and I completely control WHAT goes in my coffee. Glass is really decent quality. It's not flimsy. The plastic cover is just ok. I don't use a dishwasher, but I could see it not fairing well in a dishwasher. It works great for me and I'm saving sooo much $ now on coffee. Definitely recommend

Easy to use, but you got to find your right strength!
Style: 1pcs 64oz black
Fantastic cold brewer! My only issue is the bag of coffee for cold brew had one set of instructions (ratio of coffee to water) and the brewer had something different. So I brewed my first pitcher and now I know what I need to do to tweak it. Considering how much a cup of cold brew costs at a shop, I’m stoked to be able to make my own at home! And it was delish!!!! And you can brew it at room temp, but brewing it in the fridge will yield a smoother and less acidic taste, if you can wait that long for the result ;)
