40mm CNC Conical Burrs60 Micro-Grind StepsPlasma Anti-Static Chute350 RPM Cool-Grind
Spinning blade grinders burn coffee beans into bitter dust and sour boulders. The Cosari BaristaBurr Pro uses 40mm CNC-machined 420 stainless steel conical burrs spinning at a cool 350 RPM across 60 micro-settings—from velvety 9-bar espresso to crystal-clean French press.

When grounds are uneven, tiny 'fines' over-extract into harsh bitterness while large chunks under-extract into sour water. BaristaBurr Pro’s 5-axis CNC conical burrs slice beans at a gentle 350 RPM into uniform particles for a noticeably sweeter, fuller-bodied cup.
Hate coffee grounds sticking to the chute and spraying across your granite counter? An integrated plasma generator neutralizes static electricity as grounds exit the burr chamber, while the top silicone bellows puffs out the last 0.1 gram so yesterday’s stale coffee never mixes into today’s brew.
Switch from setting #6 for rich syrupy espresso to #32 for V60 pour-over or #54 for cold brew in one twist. Includes magnetic 51–54mm and 58mm portafilter cradles for direct hands-free dosing.

✓ Taste the Notes Printed on the Bag: within 15 minutes of grinding, coffee loses over 60% of its volatile aromatics. Grinding fresh whole beans right before brewing through BaristaBurr Pro’s 40mm CNC conical burrs unlocks chocolate, caramel, and berry notes you never knew your coffee maker could produce.
✓ True Espresso Capable: unlike cheap entry burr grinders that can’t grind fine enough to pressurize an unpressurized espresso basket, steps 1–15 offer micro-stepped adjustments for 28-second golden-crema espresso shots.
✓ Cleanest Countertop in Coffee: active plasma de-ionizing needles inside the exit chute neutralize static electricity on contact—so fluffy grounds fall straight down into your portafilter or catch cup without clinging.
✓ Whisper-Quiet Morning Operation: high-torque gear reduction keeps sound down to 64 dB so you can grind your 6:00 a.m. coffee without waking the house.

40mm CNC conical burrs produce uniform coffee particles so every brew tastes sweet and balanced.
Micro-steps 1–15 dial in 9-bar espresso shots; steps 16–60 cover AeroPress, V60, Drip, and French Press.
Built-in ionizer eliminates static cling—no more coffee chaff stuck to the counter.
Slow, high-torque gear reduction prevents friction heat from scorching delicate bean oils.
Slide your 51mm, 54mm (Breville), or 58mm portafilter into the cradle and tap the button.
One press of the silicone hopper bellows clears every last ground from the burr chamber.
Turn the brushed metal collar to match your brew method—from #8 for Espresso to #35 for Drip or #52 for French Press.
Select 1–12 cups or dial your exact dose time to the tenth of a second on the LED display.
Press Start to dispense fluffy, clump-free grounds directly into your portafilter or stainless catch cup.
Yes! That is where most sub-$200 grinders fail. BaristaBurr Pro’s 40mm 7-core CNC conical burrs and 60 micro-settings give you 15 dedicated espresso steps (down to 150 microns) to pull rich 9-bar shots on Breville, Gaggia, Rancilio, or Flair machines.
Yes. Standard grinders build up static electricity that makes chaff and grounds cling to the cup and fly onto your counter. Our built-in plasma ionizer neutralizes that charge as the coffee falls, eliminating 98% of static cling without needing to spritz beans with water.
Yes. Both magnetic cradles (51–54mm and 58mm) are included right in the box so you can grind hands-free into any home espresso portafilter.
Both! Keep up to 275g of beans in the UV-protected hopper for daily drip coffee, or weigh out an 18g single dose and pump the included silicone bellows lid to achieve <0.1g retention.
Tool-free in 15 seconds. Twist the hopper counterclockwise to unlock and lift out the upper burr for a quick brush-out.
Because the motor is geared down to a low 350 RPM inside a heavy brushed stainless housing, it hums at a gentle 64 dB instead of the high-pitched screech of high-RPM grinders.
Brew with it every morning for 30 days. If your coffee doesn’t taste dramatically sweeter and richer, return it for a full refund.

★★★★★Pulled a 18g-in / 36g-out shot in 29 seconds on my Bambino Plus
I was about to spend $299 on a Eureka Mignon or Fellow Opus for my Breville Bambino. Ordered the Cosari BaristaBurr Pro instead—set it to #9 with the 54mm cradle and pulled a tiger-striped espresso shot with zero channeling on the second try. And the plasma ionizer leaves ZERO static mess.

★★★★★Made our everyday Costco beans taste like a $6 pour-over café
We didn’t even change our drip coffee maker or our beans—just switched from our old Cuisinart loud flat-disc grinder to this conical burr Cosari at setting #34. The bitterness vanished overnight.

★★★★★0.0g retention when you pump the silicone bellows
Weighed 18.0g of Ethiopian light roast going in, gave the silicone bellows two quick pumps at the end, and 18.0g came out on my scale. Switching between my wife’s decaf and my espresso beans is effortless.

★★★★★Whisper-quiet 350 RPM doesn’t wake our baby
Our old Baratza Encore sounded like a lawnmower in our open kitchen. The BaristaBurr Pro has a deep, quiet hum that lets me make my 5:45 a.m. Chemex while the baby sleeps in the next room.

★★★★★Tip: adjust finer while the burrs are spinning or empty
Just like any precision conical burr grinder, if you jump 30 clicks finer from French Press to Espresso, run the motor for 1 second so no bean fragment jams between the burrs. 10/10 build.
