Cold brew coffee has never been hotter. Most of the major brands have ready-to-drink cold brew sold by the bottle or carton. Many cafes are now offering cold brew on tap or even on nitro.
As we’ve written before, Japanese iced coffee is our favorite way to drink coffee in the warmer months, but there are many reasons why cold brew is a great summer treat. For one, cold brew tastes a lot better with cream and sugar than other iced coffee methods. Sure, you might be a coffee snob, but you probably have a friend who likes a little dairy in their coffee. Cold brew is also a great way to use older coffee which would taste stale brewed hot. But, most importantly, cold brew is ridiculously easy to make. In fact, it’s quite possibly the the easiest way to make coffee ever. As an added bonus, cold brew is perfect for larger batches of coffee and it keeps for several days (which solves the age old dilemma, “How can you make coffee before you’ve had coffee?”).
Cold brew is quite possibly the the easiest way to make coffee ever.
The most delicious cold brew we’ve ever had was brewed with a Yama Kyoto dripper. But unless you have $250 burning a hole in your pocket and a overabundance of counter space, you’re probably looking for a simpler option. The good news is that you probably already have everything you need to make delicious cold brew. So, without further ado, here is the official Compass guide on How to Make Cold Brew Coffee with a French Press.
What You Need
- Coffee – Cold brew works best with coffees with deep sweetness. Think chocolate and caramel notes. We’re using some of this delicious Rwanda Dukunde Kawa from our friends and partners at Greenway Coffee.
- French Press – a French press is pretty much perfect for making cold brew coffee. Most are big enough to make up to a liter of cold brew, and they have a built-in filtration system. If you don’t already have a French press, Bodum makes our favorite.
- Scale – Here we are using the Acaia Coffee Scale, but any kitchen scale will do the job. We have reviewed several.
- Burr Grinder – We can’t say it enough: your grinder is the most important piece of coffee brewing equipment you own. Good coffee is the result of even extraction, which is only possible with even particle size. To have an even particle size, you need a good burr grinder. Baratza makes the best home grinder we’ve used.
Step 1: Weigh and Grind the Coffee
Most cold brew coffee recipes use a 7:1 water to coffee ratio. In other words, for every liter of water you’re going to use about 140 grams of coffee. Here we’re making a half batch, so we are only grinding 70 grams. (If you don’t have a scale this is slightly less than a cup of ground coffee. Read Five Reasons to Own a Coffee Scale while you find your measuring cup).
You’re going to use a medium-coarse grind, about the same grind size as a French Press.
Step 2: Add Water
Next, add 500ml of room temperature water. As always, filtered water aids with better extraction, but if there’s any brew method you can get away with using tap water, it’s cold brew.
Step 3: Stir
Make sure all of the grounds are fully immersed by giving the slurry a thorough stir. If you’re using a glass French press, use a wooden spoon so you don’t crack the glass.
Step 4: Wait
This the hardest part of making cold brew: waiting. With this corse of a grind, the coffee should be allowed to steep for 12-20 hours at room temperature. If you want to slow down the process, you can steep it in the refrigerator to add a few hours. Put the lid back on the French press, but be careful not to plunge it.
Step 5: Decant
Here’s the only tricky bit: push the plunger an inch or two down for stability, but avoid agitating the slurry. After steeping for over 12 hours the coffee grounds are more volatile and any agitation will release the more unpleasant bits of the dissolvable solids that are better left behind. With the screen firmly in place, carefully decant the cold brew into another vessel. Since we live in Kentucky, we like using mason jars.
For a cleaner cup, you can run the mixture through a rinsed coffee filter. This will remove the fine coffee particles that passed through the French press filter.
Step 6: Drink and Enjoy
You’ve been waiting for at least 12 hours at this point. It’s time to enjoy some delicious iced coffee. This recipe makes a concentrated brew, so you’ll probably want to cut it to taste. Plan for some dilution from the ice as well. We like to drink our cold brew in a crystal old fashioned glass with a large ice cube, preferably sitting on our porch.
Paul Butterworth says
June 30, 2014 at 11:10 amWhat grind setting on a Hario Skerton would you recommend for a French Press? You recommend 8 for v60, right?
Michael says
June 30, 2014 at 12:03 pmStart with 10. Try to make the grounds look like the grounds in the picture.
Brad says
May 3, 2017 at 10:00 amIf you’re using the Hario Skerton for french press, you should definitely add this upgrade. Makes a huge difference in grind consistency. http://www.bluehorseproducts.com/hario-skerton-upgrade-kit
Mioff Geller says
April 23, 2018 at 1:44 pmBrad, any experience with the Skerton Pro?
toddbaT says
June 30, 2014 at 12:19 pmAwesome post michael! I’ve been told multiple times about using a French Press to make cold brew but never looked at the process closely. As far as cutting it with water do you have any recommendations on ratio?
Michael says
June 30, 2014 at 12:38 pmThanks Todd! High praise coming from a cold brew fiend such as yourself. As far as cutting goes, I would try anywhere from 1/4-1/3 water. Obviously it’s easier to add more water, so start small. To try it “New Orleans style” cut it with milk instead. Let me know how it turns out for you!
Craig Helmen says
September 3, 2014 at 10:25 pmI tried this with 70 g of griunds and 500mls of water. The next day, the grounds had soaked up the water and there was nothing to decant. I used a french press. Any thoughts? Thanks
Michael says
September 3, 2014 at 10:46 pmWow. I’ve never heard of that happening. It’s possible that your coffee was too finely ground. Try using the same coarseness as a French press. If you’re using coffee ground for autodrip try only steeping it for 8 hours.
Jacky says
October 8, 2014 at 2:12 pmWhat amount of the resulting cold brew concentrate would you recommend per cup, with water and/or milk added? I tried 6 ounces after brewing it in the fridge for 12 hours, which I then realized wasn’t long enough in the fridge. The second time I made it, I brewed it at room temperature for 36 hours and it tastes stronger, so I cut 3 ounces of cold brew with 5 ounces of coconut milk and water.
Michael says
October 12, 2014 at 11:18 pmWe usually cut our cold brew with about 30% water, but that is simply a preference issue.
Cathryn says
October 13, 2014 at 10:38 amHello Michael, beautiful instructions. I want to make hot (not warm) coffee from the concentrate. do I need to make it even stronger?
Michael says
October 14, 2014 at 10:21 amThank you Cathryn! I would not recommend heating cold brew coffee. That’s going to cause a lot of the acids in the coffee to breakdown into quinic acids, which tastes really bad! For hot coffee it’s hard to find a simpler brew method than a Clever dripper: https://www.thecoffeecompass.com/3-best-coffee-accessories/
Cathryn says
October 14, 2014 at 12:57 pmThat is good to know. My quest is to find or create a low acid coffee. As a long time coffee drinker (grinding the beans and using the pour over method) I now find I cannot handle the acid any longer. I live in the Pacific NW and am not a fan of iced coffee. Appreciate your reply, greatly.
krystl says
July 19, 2016 at 10:54 pmI’ve heard of a “dutch americano” which is cold brew in hot water…I tried making it with a cup of hot water and a few ounces of cold brew concentrate and it was still pretty dang smooth.
Jared says
November 16, 2014 at 6:44 pmWhen you say “plunge an inch or two,” do you mean an inch or two below the spicket on top, or an inch or into into the slurry?
Michael says
November 16, 2014 at 10:58 pmHowever much is necessary to ensure the lid is stable. The important thing is to filter out the grounds while agitating them as little as possible.
michaelstroup says
March 3, 2015 at 1:34 pmThis looks awesome. I have tried this before but never got it to taste right but now that I read this, maybe I was using the wrong coffee.
Ruthie Serrano Peppy-ham says
April 11, 2015 at 8:33 pmWhat kind of scale is that?
Meagan says
May 6, 2015 at 11:13 amOh WOW! I made this yesterday with locally roasted Peru coffee then decanted through my Pourover filter and tried it for the first time this morning and it is AMAZING! I cut it with milk (and okay, a small scoop of locally made vanilla ice cream – just to help keep it cold of course) and it tasted just as good as a fancy coffee shop drink – better actually since it didn’t come with a $5+ price tag. I think I may have to track down some decaf beans so I can drink this heavenly stuff in the evenings too. Thanks so much for posting this!
Michael says
May 8, 2015 at 10:57 amYou’re welcome! Thanks for trying it.
Teddi says
June 3, 2015 at 2:21 pmMichael, if you haven’t already….make ice cubes with your brew…then your iced coffee won’t get watered down with the ice cube you put in your glass!
Stuart Nottingham says
June 22, 2015 at 8:10 amI’m looking for an easy way to make coffee while cycle touring. Could the coffee/water mix be done in a separate container then poured into the press for straining?
Michael says
July 22, 2015 at 2:59 pmAbsolutely! That being said it’s hard to beat an Aeropress for compact coffee brewing!
Steven Keirstead says
July 20, 2015 at 7:24 pmOne math quibble, 7/1 is a fraction not a ratio. A ratio of 7:1 would equate to 125g of coffee grounds per liter there being 8 parts 7 water and 1 coffee. While a 140g is 1/7 of a water liter’s mass, that is actually a 6:1 ratio of water to coffee. Even 125g is much more coffee than I typically use a hot brew in my French press, so I’m trying that out (actually 130g, since I didn’t stop grinding in time). I’ll brew it overnight and see how it tastes. Sorry to be critical but I did go to the North Carolina School of Science and Math, and even though Science was my strong suit not Math, I do get bugged by obvious math errors.
Michael says
July 22, 2015 at 2:58 pmThanks for the critique, I edited the post to reflect it. I should have been more clear in the article, the ratio refers to the ingredients and not the finished beverage. The total mass of the slurry in this recipe would be the water plus the coffee. The finished beverage will end up being less than a liter, as the grounds will absorb a considerable amount of the water.
Steven Keirstead says
July 22, 2015 at 3:08 pmGreat! It does absorb a lot of water. I diluted with milk and added some hot water suspended cocoa powder/sugar mix with a pinch of sea salt, that I also made the night before and chilled, and the mix was terrific for iced mocha coffee for a hot summer morning.
Jill says
July 22, 2015 at 1:22 pmSo you don’t plunge the plunger all the way down? Just the 1-2 inches and then pour it into a different container?
Brian says
August 12, 2015 at 7:01 pmI was needing to know this also, not clear above and didn’t want to mess it up.
Lynn says
March 17, 2016 at 3:24 pmI’m confused on this point, as well. It says to not disturb the grounds, but as I read the instructions, I assume it means to push the plunger down 1-2 inches, and then tip the whole thing so it pours into a glass. Wouldn’t this agitate the grounds any way because you’re moving the whole thing to pour out the liquid contents? Couldn’t you just push the plunger all the way down to stamp the grounds to the bottom, and THEN pour out the liquid? It seems to me like the agitation would be similar either way.
Sarah Tarko says
August 17, 2015 at 7:09 pmHow many glasses on average would this make? Iced of course. Thanks
Michael says
August 17, 2015 at 8:32 pmThat largely depends on how much you want to dilute the concentrate. You should be able to get at least 3-4 cups out of this recipe.
kate says
April 15, 2016 at 12:03 pmhow long will a batch of this last? a few days?
Michael says
April 19, 2016 at 1:22 pmIf you keep it refrigerated it should keep for several days.
Mira says
May 27, 2016 at 5:35 pmDoes this make a concentrate, or does this make ready-to-drink cold brew? Because 140 grams of ground coffee fills my 1 litre French press halfway… That seems like an insane amount. Yes, I have a good scale.
Adam Morrone says
June 8, 2016 at 7:56 pmSo for clarification: we only press the plunger down an inch or two, and then pour the whole thing? We’re NOT pressing the plunger all the way down?
Alex Kitáin says
June 16, 2016 at 3:21 amThe only thing I always find annoying is that the yield is a lot less and when you filter the cold brew through a regular Kalita or V60 filter they always get clogged.
I made some last night with the French Press, 750ml -> 115g of coffee. I used the Nano Chala from CafféCouture in Vienna. It’s super smooth.
David @ MilkFrotherJudge says
July 23, 2016 at 2:58 pmWas looking for this recipe to stop spending money at Dunkin Donuts. I’m enjoying my first glass, but I did add 5 teaspoons of carmel sauce. Thanks for this..
Christina says
October 9, 2016 at 10:46 pmSo ok, I consulted the trusted barista at my local Starbucks (as I know their cold brew is insanely good) and she recommended their Komodo Dragon blend. Thanks for the good instructions and recipe.. I am now at Step 4 (waiting) and hoping for / looking forward to a great mid-Morning pick-me-up tomorrow!
Cindy says
March 5, 2017 at 2:07 pmGreat read! Just came across your site. When you weigh the beans are you including the glass into the 140grams weigh in? Planning to make my first batch. Thanks
Michael says
March 7, 2017 at 2:57 pmNo. We tare the scale with the receptacle already on it.
Victoria Olson says
March 21, 2017 at 9:45 pm140g is a LOT of beans, about 2 cups/ of grounds. That means ~3 liters of coffee from a 12 oz bag. Also, i grind by hand with a ceramic burr mill for accuracy, 140g took 20 minutes. It’s sitting in the fridge right now, hoping for the best outcome.
Michael says
March 23, 2017 at 11:01 amCold brew is one of the least efficient brew methods when it comes to coffee use. If you’re looking for a more efficient iced coffee recipe try Japanese iced coffee (there’s a link in the post).
Rose says
October 15, 2017 at 3:02 pmI’ve been a French Press coffee drinker for years (at the moment I have three) and then I became addicted to Starbucks ice coffee (it’s the filtered ice, I swear). Then they introduced me to Cold Brew and I drank the Kool-aid 😉 spending $5 a day forever. Then I got the BRIGHT IDEA to use my French Press (didn’t know you had been there, done that). I’m excited to have come across your site and I’m trying it YOUR way–think I didn’t stir it long enough before letting it sit–I too was confused about that 1 1/2 inch thing–enlighten me–I plan to plunge very slowly in 18 hours.
Pjbeee says
August 25, 2018 at 12:30 pmIf you don’t mind some particulates in your coffee – and I don’t (most of them settle anyway) – a blade grinder will work fine. I do like a French press for hot coffee as well, for the same reason we like cold brew. There is a depth to the flavor due to the steeping time, and those coffee oils, and who knows what else, have a mellowing effect.
Terry says
November 2, 2018 at 9:08 amI stumbled across cold brewed coffee via a French press on my own. I use an antique hand grinder which is set for a coarse grind. One trick I’ve not seen mentioned is using a paper filter. I place a paper filter over the screen filter in my Bodun, which then provides very clear coffee. The extra resistance of the paper filter means it has to be pressed slowly.
Since the coffee hasn’t been heated, it can keep all day without getting stale or bitter. I just pour what I want and nuke it!
