Hi Deb, here is a natural cleaner for concrete that you can make with baking soda. Hope it helps with the coffee... https://www.diynetwork.com/how-to/maintenance-and-repair/cleaning/how-to-clean-a-cement-patio#:~:text=Mix%201%2F2%20cup%20baking,may%20need%20a%20pressure%20washer.
Hi Deb, a good scrubing with hot soapy water and a brush may work. If not, Ihere's what I found online... hope it helps!
A poultice saturated with a solution of 1 part glycerol to 4 parts water. Allow to react with the stain for at least 24 hours before removing and hosing affected area. The area may need to be scoured with abrasive cleaning powder to remove the remains of the poultice
If liquid detergent doesn't take it out, try some vinegar and water 50/50 and scrub it.

There is a lot of information on removing stains on this site. I pasted the info on coffee stains here:
"Coffee stains: Scrub stain vigorously with warm soapy water and then rinse with clean water. If this is not effective, try a poultice saturated with a solution of 1 part glycerol to 4 parts water. Allow to react with the stain for at least 24 hours before removing and hosing affected area. The area may need to be scoured with abrasive cleaning powder to remove the remains of the poultice."
One of these should work
WD-40. Did a leaky oil pan leave a big ugly spot in the middle of your concrete driveway? To get rid of an unsightly oil spot, just spray it with a generous amount of WD-40 and then hose it down with water.
Soda (Coca Cola). Here’s how to remove oil stains from concrete drive-ways and garage floors: Gather up a small bag of cat litter, a few cans of cola, a stiff bristle broom, bucket, laundry detergent, bleach, eye protection, and rubber gloves. Cover the stain with a thin layer of cat litter and brush it in. Sweep up the litter and pour cola to cover the area. Work the cola in with a bristle broom, and leave the cola for about twenty minutes. Mix 1/4 cup laundry detergent with 1/4 cup bleach in 1 gallon (3.7 liters) warm water and use it to mop up the mess.
Oven Cleaner. Get those unsightly grease, oil, and transmission fluid stains off your concrete driveway or garage floor. Spray them with Easy Off No Fume Oven Cleaner in the BLUE can. Let it settle for 5-10 minutes, then scrub with a stiff brush and rinse it off with your garden hose at its highest pressure. Severe stains may require a second application.
Kool-Aid. Nasty rust stains on your concrete? Mix unsweetened lemonade Kool-Aid with hot water. Scrub and the rust stain should come right out.
Baking Soda. Salt and commercial ice-melt formulations can stain — or actually eat away — the concrete around your house. For an effective, but completely innocuous, way to melt the ice on your steps and walkways during those cold winter months, try sprinkling them with generous amounts of baking soda. Add some sand for improved traction.
Ammonia. Tired of those annoying discolorations on your concrete work? To get rid of them, scrub with 1 cup ammonia diluted in 1 gallon (3.7 liters) water. Hose it down well when you’re done.
Removing Coffee Stain
You let the dog out first thing in the morning and trip over the door sill– launching coffee all over the concrete patio. It happens to the best of us. Coffee is tannic, like wine, so you can use a 1:4 ration of glycerin to water on a sponge to scrub and remove it. After scrubbing, rinse and repeat as needed.

I would use bleach and water

Power wash with a good cleaner degreaser such as Purple Power or go to an auto store and buy a degreaser.
Hello. We use this kitchen product on our concrete stains.

Bleach should clean it if it doesn’t use CLR cleaner sold a home depot
Hello,
Try using Bleach or soapy water to scrub it. or use a special stain remover for concrete.
If possible use a scrub brush and Dawn dish detergent before pressure washing. Stay safe!
I would have though regular dish detergent and a scrubbing brush should work. If not I would try a power washer.
