Can confirm, it worked great on a stubborn coffee stain today
Correct. It's something in Angostura bitters, used in the old fashioned, that creates stains really easily. Red wine is no prob. Coffee even is no prob. But Angostura has something in it. Barkeeper or wine away will get it out.
Good to know!
I have the bitters in my bar that has quartz countertops. I’ll be extra careful adding the bitters now.
Don't stress too much. I've accidentally hit my white quartz with ango a few times now. While it is yes one of the few things that won't wipe away with near-zero effort, Wine Away has lifted it off every time and liquid BKF I'm sure would work if left overnight.
Which liquid version of barkeepers friend? There seems to be a lot of options

It’s Oxalic Acid and mild abrasives that are the magic
I was wondering this too. My countertop had zero stains on it then my brother moved in and started finding them left and right. Mostly because he doesn't use a sponge to clean up his cup rings before he leaves.
I had a rust ring left from a cast iron pan sitting on my white quartz countertop overnight. It was impossible to get off. Until I tried wet baking soda and a copper scouring pad. Made quick work of it. It really comes down to using an abrasive rather than a cleaning chemical.
I've been able to clean off every stain from mine using wet baking soda without the scouring. Just make a past, press into the stain, then come back in 5+ minutes. It's gone like magic.
I've had success with baking soda.
I've had success with baking soda too, if mixed with an acid (lemon juice or vinegar) and left to sit as a paste.
Baking soda + acid = bubbly water with some sodium citrate (lemon juice) or sodium acetate (vinegar).
Stop mixing baking soda and vinegar.
Learn which is appropriate where (does the job need an acid, or a base?) Or does it not matter, because you need an abrasive like in this case?
Good to know, I suppose.
I always assumed that scrubbing would be worse for the surface than simply leaving the mix to bubble on its own. It's always worked for me with no negative effects, just sharing my own experience.
Your experience is ruining your quartz.
Vinegar is acidic even if you mix it with baking soda and that doesn’t magically neutralize the acid in the vinegar. You’re gonna ruin your quartz with that.
one thing you might want to try before abrasives:
I've had decent luck using boiling hot water. Just pour a little bit on the stain, then lay a rag over it to keep it in place for a minute or so and wipe it off.
I poured hydrogen peroxide on a stain on our quartz countertop and it pulled it all out.
Barkeepers, might need to soak for a moment if it is stubborn.
Diotamaceus earth. Let it sit on the spot over night and not will soak up the stain.
Like others I have used a baking soda and then soak it in hydrogen peroxide and was able to get all the stains out of my quartzite countertops
My countertop installer used a combination of powdered barkeepers friend and acetone to clean the countertops after install, being careful not to scrub.
I use a paper towel with liquid barkeepers friend, and then I clean the area with normal products afterwards (because it's an acid).
I have Cambria quartz countertops and when they came out to fix a small manufacturing defect I asked what I should use to clean them if they stain and he said liquid barkeeper's friend that comes in a spray bottle. I've used it to clean tea/coffee stains that wouldn't come up with normal scrubbing. Works perfectly.
Foam barkeepers friend.
There is a specific type of Barkeepers Friend that is for quartz countertops
I used the pink stuff
Softscrub works well
Hand sanitizer!
This is about levels of escalation.
Abrasives will work. They should be the last things you try.
Start with things that “can’t hurt.” (Not all at once!!)
Boiling water.
Dawn detergent.
Spray Lysol.
Shout laundry spray (let sit, wipe off).
A denture tablet, crushed and poured on as powder, activated with a spray bottle of water. DO NOT SCRUB.
Move on to non-abrasive liquids that can damage a finish:
Lemon juice. Peroxide.
Then? Gently try the abrasives….
Try spraying with aerosol lysol. Works like a charm.
Why does it stain isn’t it sealed?
Ceasarstone recommends the liquid version of barkeepers friend. Worked very well here
