Every detail of the Cosari GlassPress 1000 is built for flavor purity, stone-counter stability, and a 30-second sink cleanup.
Molded directly into 2.8mm high-borosilicate glass with zero metal bands or plastic collars, staying comfortably cool in your hand even with 205°F water right off the boil.
A full-perimeter spiral spring coil presses the fine 304 stainless steel mesh snugly against the glass wall—trapping coarse coffee grounds and whipping warm milk into thick microfoam in 15 pumps.
The matte black flared boot absorbs impact on stone countertops, prevents sliding while you plunge, and pops straight off at the sink so water never pools underneath.
A pronounced triangular pouring spout shears the liquid stream cleanly at the end of every pour—keeping white countertops and office paperwork spotless.
Pour 205°F water right off the boil over coarse grounds and watch the golden-mahogany bloom unfold through unobstructed laboratory-grade glass—with 0.0 grams of plastic anywhere near your brew.
Rest your palm on the wide 32mm flat stainless steel knob and press smoothly downward. The matte black flared base grips your counter while the tensioned stainless mesh sweeps grounds cleanly to the bottom.
Decant a rich, grit-free cup through the triangular V-shaped glass spout without a single side dribble, then pop off the black base boot at the sink for an effortless 30-second rinse.

Architectural Glassware Meets Daily Utility: The Cosari GlassPress 1000 replaces clunky plastic-framed carafes and blind metal thermoses with an unbanded high-borosilicate glass cylinder, a solid integrated glass C-handle, a precision triangular V-spout, and a 304 stainless steel plunger assembly.
4-in-1 Versatility: Hot Coffee, Cold Brew, Tea & Milk Foam: Because borosilicate glass and 304 stainless steel never retain oils or odors, you can switch from morning single-origin coffee to afternoon loose-leaf tea, overnight cold brew concentrate, or 15-pump latte microfoam with a simple rinse.
Tool-Free 5-Second Plunger Breakdown: Want to deep-clean the micro-mesh filter? The stainless steel cross-plate, spiral coil, and mesh screen unscrew by hand in 5 seconds without tools, and the matte black flared base pops right off the glass cylinder.
Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.

2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.
Even $40–$100 name-brand presses hide polypropylene plastic liners or silicone gaskets inside their lids right over boiling water. Cosari uses 100% 304 stainless steel and borosilicate glass.
Engineered from 2.8mm thick laboratory-grade borosilicate glass, the carafe accepts water straight off a rolling boil or ice-cold refrigerator steeps without thermal stress.
Traditional metal and plastic cages trap soapy dishwater against the glass where it can't dry. Cosari's flared black boot pops off in one second so every surface air-dries spotless.

Add coarse-ground coffee to the crystal-clear borosilicate carafe and pour 205°F water right off the boil. Watch the rich golden bloom through the unbanded 360° glass wall.
After 4 minutes, press the wide flat stainless steel knob steadily downward. The matte black flared base holds firm on granite counters while the tight stainless mesh locks grounds at the bottom.
Pour a crisp, drip-free cup through the triangular V-spout, then pop off the matte black base boot at the sink for a complete 30-second rinse with zero trapped water.
I like that the curved handle is part of the glass. My old press had a plastic cage that collected coffee water underneath. The triangular spout pours nicely too, without leaving a drip down the side.
The black base makes a bigger difference than I expected on our granite countertop. It doesn't clank when I set the press down, and it stays put while I'm pressing the coffee.
The mesh fits snugly against the glass. I use the coarse setting on my hand grinder and there's hardly any sludge left in the bottom of my mug. Much better than my old press.
I wanted a straightforward glass press without plastic touching the hot water. The polished stainless lid and plunger rod feel solid, and the mesh assembly unscrews easily when I want to give it a thorough cleaning.
I mostly use this for loose leaf tea and cold brew concentrate. The clear glass cylinder and glass handle look lovely on my counter, and there aren't any metal bands blocking the view of what's brewing.
The flat metal knob on top is wide enough for my palm, which makes it comfortable to press down. The plunger goes down smoothly without wobbling around, even when I'm making a full pot.
I've used this every morning for two months and pour water in right after it boils. The glass has held up without any issues, and the glass handle stays surprisingly cool when I pour my coffee.
I use it for my morning coffee, but lately I've been using it to froth warm milk for lattes too. About 15 pumps with the mesh plunger gives me a nice thick foam.
The glass rinses clean really quickly after I empty the grounds. I also pop the black base off before putting it in the dish rack, so water doesn't sit trapped underneath it.
I keep this and an electric kettle at my desk at work. The triangular spout cuts off the pour cleanly, so I'm not constantly wiping coffee drips off my desk or worrying about rings on my paperwork.

No. Zero plastic ever contacts your brew. The carafe and integrated C-handle are molded from 100% laboratory-grade high-borosilicate glass, and the lid, plunger rod, cross-plate, and micro-mesh filter are made entirely from food-grade 304 stainless steel.
No. Unlike permanent plastic or metal cages that trap dirty dishwater against the glass, the matte black flared countertop boot on the Cosari GlassPress 1000 pops straight off in one second so both the glass bottom and the protective boot rinse and dry completely.
No. High-borosilicate glass has very low thermal conductivity, and because the solid curved C-handle is thermally isolated from the main cylinder wall, it stayed below 91°F in our infrared tests even after pouring 205°F water straight off the boil.
The 304 stainless steel 100-mesh screen is tensioned by a full-perimeter spiral coil that hugs the inside of the glass wall tightly, keeping coarse grounds pinned at the bottom. Only powdery espresso-fine pre-ground coffee will pass a tiny bit of fine silt if plunged too aggressively.
Yes. Because the unbanded clear glass cylinder neither absorbs odors nor blocks your view, it is ideal for steeping loose-leaf tea and overnight cold brew concentrate. You can also pour warm milk inside and pump the plunger 15 times to whip up thick microfoam for lattes.
Brew with the Cosari GlassPress 1000 for 30 full mornings. If you aren't thrilled with the clean V-spout pour, zero-sludge filtration, and 30-second sink rinse, send it back for a full refund. Your press is also covered by a 2-Year Thermal-Glass & Stainless Hardware Warranty.
