No plastic pitcher, no nylon sock, no paper filters. Just materials that rinse clean and stay neutral batch after batch.
A full-length 304 stainless steel cylinder with laser-cut mesh keeps grit out of your glass. It left 0.04g of silt in our filter test.
Lab-grade glass rated from -20°C to 150°C, with an integrated glass handle. It does not stain, cloud, or hold old coffee smells.
Two food-grade silicone rings seal directly to the glass rim, keeping fridge odors out and your brew fresh for up to 14 days.
At 10cm (3.9in) wide and 26.5cm (10.4in) tall, it slides into a standard door bin and keeps your main shelves free.
Scoop 85–100g of coarse ground coffee straight into the wide-mouth stainless filter core seated inside the carafe. No funnel needed.
Pour filtered water slowly through the top of the core to the 1200ml line, give it a 5-second swirl, and press the lid down to seal.
After 12–18 hours, lift out the core and pour smooth, grit-free concentrate from the V-spout over ice.

Scoop coarse grounds into the steel core, then pour water slowly through the top and give it a quick swirl so every ground gets wet.
Press the lid down until it seals and slide the carafe into your fridge door to steep for 12–18 hours.
Lift out the filter core, rinse it in 15 seconds, and pour smooth cold brew over ice.
Highly recommend this pitcher, it is so easy to use. Brews delicious regular cold brew, or a really strong concentrate if you leave the filter core in longer. I love the sturdy glass handle, the fine stainless mesh, and that the black lid shuts completely airtight.
I love it! I can make a $10 bag of coffee go way further than buying jugs of cold brew from the grocery store. Just fill the stainless mesh core with coarse grounds, let it steep overnight, and I'm set for days.
This is the perfect in-fridge cold brew pitcher. The slim borosilicate glass body tucks neatly onto my refrigerator door without hogging shelf space. I'm saving good money brewing at home, and it cleans out fast for a fresh batch.
Makes the best tasting iced coffee I've had at home. What sold me is how simple it is to clean—you just lift out the cylindrical stainless steel mesh filter core, dump the spent grounds in the trash, and give the tube a quick rinse.
Really like this cold brew maker. The borosilicate glass carafe is noticeably taller and more slender than I had anticipated, with clear measurement markings up to 1200ml on the side, so check your shelf height. Does a great job steeping.
This is a fine product. Super easy to use and cleaning is a breeze thanks to the removable stainless steel filter tube and wide-mouth glass carafe. No awkward corners where old coffee oils get stuck.
Total must-have if you drink iced coffee every morning. Prep takes maybe two minutes—scoop coarse grounds into the metal filter, pour cold water over them, and pop the glass pitcher in the fridge overnight. Waking up to ready coffee is the best.
A few guys at work told me to just use a regular French press for cold brew, but this dedicated carafe is a much better investment. The ultra-fine laser-cut stainless filter core leaves zero gritty sludge at the bottom of the glass.
Brews super smooth coffee or dark concentrate if you leave the grounds in a full 24 hours. The integrated glass handle feels solid with a full load, the V-shaped spout pours without dripping down the side, and the ml markings make portioning water easy.
Between stretching a $10 bag of beans and how well it stores, I couldn't be happier. The silicone-gasketed black lid locks down tight so my cold brew stays fresh in the fridge all week without picking up any weird refrigerator odors.

It measures 26.5cm (10.4in) tall with a 10cm (3.9in) base diameter, which fits most standard gallon and condiment door bins. It is too tall for cramped 7-inch middle shelves.
Total brim capacity is 1500ml with graduations to 1200ml. After coffee grounds displace volume, a full batch yields about 34–38 oz (1000–1120ml) of concentrate.
Yes. The dual-gasket silicone lid seals directly onto the glass rim with or without the stainless filter core inside.
Lift out the filter core, tip the grounds into the trash or compost, and rinse under the faucet for about 15 seconds. The glass and steel are both dishwasher safe.
Yes. The borosilicate glass is rated from -20°C to 150°C (-4°F to 302°F), so it handles hot tea and cold infusions.
Medium-coarse to coarse, the same grind you would use for a French press. Pour water slowly through the top of the core and give it a quick swirl before sealing.
