Ideal coffee grind for a French Press?
I recently picked up this Bodum "French Press" style coffee maker and so far, I'm really enjoying it for its simplicity. But I'm curious how I should be grinding my coffee.
When I bought it, I grabbed a bag of pre-ground coffee at the grocery store and this worked well. But recently, I bought a can of beans and put it thru the coffee grinder at the store and I may have chose too coarse a grind as I seem to be getting very weak cups of coffee now.
The manual said pick a "coarse" grind, so it turned the dial all the way to the left labeled "coarse". I'm thinking it should have been somewhere in the middle, like "Percolate".
Any advice on the optimal grind?
EDIT: Also, What ratio of Tbsp to oz of water? (or grams to ml, if you prefer metric.)
We've gotten weak coffee with a coarse grind in our French press also, so I don't understand why the manual insists on a coarse grind. I'm curious to see what others say.
I know this isn't really relate to the question but, I used to dig the french press coffee makers, but since I got a Moka I've never looked back. They make *much* superior coffee in my opinion, and I'd never go back. plus they are much stronger and won't smash, which happened to a french press I had.
@Sam Holder: I have one of those and I have never been able to produce anything but extremely bitter coffee. Maybe I should start another question to ask this, but how do you make palatable coffee from one of those? I drink my coffee black, so adding milk to the final result isn't an option. I have modulated grind size, temperature of stove, etc. all to no avail.
@Kevin Selker: we've steeped it anywhere from 4-15 minutes (ok, probably longer--sometimes I forget). We've only gotten weak coffee with a pretty coarse grind; we ground it at the grocery store on their French press setting. Since then, we just gave up on coarse grind and grind it more finely.
@Rebekah: There's a "french press" setting? My store doesn't have such a setting. Where did it fall on the scale? (iow, what settings were on either side of it?)
Realistically, if you use a french press because you want fuller bodied coffee. I couldn't stress more to you the importance of 1)grinding your own beans directly before brewing them 2) Use a fresh roasted coffee. Check you're local coffee shops, otherwise tonx has great coffee that you can subscribe to.
Serious Eats has a nice article on French Press brewing: http://www.seriouseats.com/2014/07/how-to-make-better-french-press-coffee-tips-technique-grind-timing.html where they also suggest to start with a coarse grind and move to a finer grind for a stronger cup of coffee. I also find the strength of the coffee to be correlated with the granularity. I don't think any granularity is wrong per say; instead, just expect a different cup of coffee (e.g., more "sludge" or bitterness from finer grinds -- neither of which is necessarily bad).
You do want a coarse grind for french press coffee. The key is letting the coffee steep for long enough to make a strong brew. I have good results with a 5 minute steep time. Be sure to use a timer, and compare different times to find the optimal brew. As a general rule, if you are at altitude, then you need to add time because boiling water is cooler. (Note that I am at 5000ft, so 5 minutes may be too long for you.)
Below is a picture of the coffee chunks in a coarse grind on top of a US 5 cent coin (21.21 mm in diameter).
The picture is from this article.
EDIT: The reason to use a coarse grind for a french press is that finer grinds will get stuck in the filter and/or push their way through. This has three potential problems: 1) it will be harder to press down the filter, possibly leading to spillage or breakage; 2) your coffee will have grinds in it; 3) the coffee may become bitter, as the finer grinds that passed through the filter remain in contact with the coffee for too long.
I'm inclined to pick your answer so far, but the thing is I have been doing what you describe. Also, my GF made the coffee this morning. She used 5 heaping Tbsp to 18oz of water. Should we just up it to 6 Tbsp? (3oz to 1 heaping Tbsp ratio) -- We chose 18oz because that seems to produce exactly 2 cups of coffee.
@Pretzel: You could try using more coffee, but that sounds sufficient to me. I would start looking for other factors that may be causing the problem (has it been a long time since the beans were roasted? Is the roast not dark enough?). Also, make sure that the "coarse" grind at the store is really giving you the proper size chunks--it's possible that the grinder is just bad, so try using other grinders. If you use a finer grind and still avoid problems 1-3 above, then it's coarse enough!
I've used a French press for many years and use a coarse grind. My grind looks like Kevin Selker's pic above. One thing I do though is to stir the grinds just after adding the water to the French Press before inserting the screen.
Stirring and a 5 minute steep is what I do with my little French press at the office.
I have a $10 French press that serves me well. on my grinder, I set the dial right smack down in the middle for medium.
A BIG HOWEVER
- I find that my grinder's medium is comparable to the grocery market's Light coarse or even coarse.
- What i do sometimes if my grinds are too small is actually i put a coffee filter under the sieved area of the press
THE COFFEE HOUSE FRENCH PRESS BREW METHOD: The Hows and Whys
USE CLEAN, COLD WATER. Brewing with a French Press is simple and easy. You have to know how to do it and WHY you are doing it to extract the most flavor possible. Essentially, your water flavor must be good so you begin by using cold, filtered water. You fill your kettle with TWICE the water needed: half to pre-warm your Press and the other half for brewing.
USE THE RIGHT DOSE OF COFFEE BEANS. Dose coffee beans at 55-65g of coffee beans per liter of water, or 70 grams if you "break and clean" (rather than stirring the bloom, you break the bloom foam cake and spoon out the surface grounds to reduce the fines, in which case you sacrifice some brewing grounds, so you need to over-dose a bit). Use a kitchen scale to measure.
BEGIN GRINDING THE BEANS JUST BEFORE THE WATER BOILS. Once the bean husk is cracked open favor immediately escapes, so wait until the last minute to grind, just as the water begins to boil. I can recommend Baratza grinders, by the way.
BREW AT THE CORRECT TEMPERATURE. As the water almost boils, start your grinder, pre-warm your Press with half the off-boil water, empty the Press and fill with the grounds weighed on a scale. Then pour in the other half of the water, using a scale to measure, at about 205-208 degrees F so as the temperature drops during the brew you are NEVER brewing lower than 195 degrees F. NEVER begin at 195 degrees F or flavor really suffers as the temp at brew's end can even drop to 185 degrees F...not good!
BREW FOR THE CORRECT TIME. A four-minute brew cycle is highly recommended. Anything less gives you a raw, under-extracted cup, anything more gives you an over-cooked, over-extracted, bitter cup. At Brew's end, ALWAYS pour out coffee into cups to terminate the brewing. NEVER store coffee in any coffee brewer as it will continue to brew! Even with drip brewing coffee is stored in a carafe...do that same here. A coffee brewer of any kind is NOT a coffee storage carafe. That is a job for a thermally insulated carafe. The insulation in a French Press is there to keep the brew at the correct temperature DURING the brew cycle.
BREWING IT: An Up-close Look at Brewing French Press Coffee
FILL KETTLE with at least TWICE the water needed to brew. Use only fresh, never-boiled, COLD, FILTERED water, not the nasty tasting, mildly rusty hot water sitting inside your hot water heater. Now begin heating your water at high heat.
WEIGH YOUR BEANS. While the water heats, place your grinder's grounds-collecting bin on your scales, then tare to zero. After weighing, pour the beans into the grinder's hopper, then place the grounds bin in the grinder to catch the grounds when you grind.
GRIND YOUR BEANS. Set your grinder to a mid coarse setting, as coarse as coarsely ground pepper, and experiment to get the dosage just right for your taste...I like the finer side of coarse. When your water almost boils, at about 210-211 degrees F, turn off the heat and start your grinder and let the water temp drop a bit in the meantime.
WEIGH WATER AS YOU POUR, THEN STEEP. While the grinder is grinding, pour hot water into your Press to warm it. When the grinding is completed, pour the warming water from the Press into your cup(s) to pre-warm them, discard remaining water from the Press.
Then pour your coffee grounds to the Press and place your Press on your scales, tare the Press to zero. To monitor heat place a thermometer in your Press. Now pour in the kettle's remaining 205-208 degree F water into the Press as shown on your scale (I use 870-900g in my 1 liter Press). Place the lid on the Press with plunger extended upward to begin the brewing cycle. Set your timer to 4 minutes.
STIR, SINK, OR SCOOP OFF THE BLOOM. After after one minute, either gently stir, or sink the bloom with a spoon, or remove (break) the cake "crust" with a soup spoon (or two) to gently scoop to remove (clean) the bloom off the top to reduce the amount of fines in the brew. Be sure no grounds remain above the plunger or in the spout as those grounds will end up in your cup.
REPLACE THE LID AND FINISH BREWING. With the lid on, continue to brew until the timer beeps, then press the plunger down VERY SLOWLY to the bottom (to reduce agitation of any fines present). Pour out the warming water from your cup(s), THEN pour in the hot coffee from the Press to replace it. Serve and enjoy. This is the ambrosia people are talking about...properly made French Press.

Consider buying a grinder and grinding the beans as you need them. As soon as they are ground (at the supermarket), their flavour diminishes fast due to the increased surface area. That's why it smells so good when you grind them! Wouldn't you rather that flavour be in the coffee you brew?
For french press, you can get away with using a cheap "whizzy" blade grinder like this one. For most other types of coffee, you should really use a conical burr grinder like this one, which makes for a more even grind and doesn't heat the coffee as it grinds.

yeah, I know about the whole "don't grind your beans at the store or it will lose its flavor" phenomenon. Truthfully, I go thru coffee too quickly for it ever to go bad or lose its flavor. Perhaps if I didn't consume as much coffee as I do, I would grind my own, but I've found that doing that requires yet another gadget and practicing until I get the grinding perfect. Plus its noisy.
I've become such a coffe snob since using my French press about a year ago. It truly makes the best coffee. I grind the beans as fine as dust and then I wrap a paper towel (as a filter) around the screen before plunging. I steep for 5min and I check my water temp to between 195-200 Farenheit before adding it. Any hotter and it tends to burn the coffee. I have a $10 press I bought at IKEA and it works just fine, it gets a lot of use to. I used to use a coarser grind but the flavor is just not the same.
Our press is a smaller version of yours, and we use 1 TB of whole beans for every 4 ounces of water. Our pot makes a maximum of 12 ounces.
We have our own coffee grinder, a Black & Decker SmartGrind. There are no settings for the grind; it's a matter of holding down the button. I pulse the button about a dozen times, and that works well.
When the coffee has turned out too weak, the problem has always been that I did not grind the coffee enough. I have not had a problem with too many fine grounds missing the filter. Just don't drink that last sip of coffee, and you'll be fine.
I've been using a french press for a few months now, Bodum brand... the 'Brazil' model I think. Since I had read to use a coarse grind, that's what I've been doing, and it's worked well ('coarse' being what the coffee grinder at the store designates as 'coarse').
Recently though, I was given as a gift a bag of coffee ground in filer-brew or coffee pot style - i.e. finer than 'coarse.' But I decided to try it in the french press anyway, and it turned out well. No clogged filter, not too much leakage (as in coffee grinds getting through the filter), and it made quite a stronger brew as well. A little bitter - if you 'steep' coarse grind for about 5 minutes (I do, to good effect usually), then maybe this only needs to brew for about 3 minutes at most. Or maybe I just used too much ;P
My Bodum Bistro grinder has a French Press setting which is all the way coarse. I've just brewed my best press pot yet (I'm a press pot newbie) with a grind two steps finer than that, a brew time of 4 minutes, using one rounded tablespoon of coffee per cup. This pot was very rich and satisfying. I saw your argument for not having a grinder and have to ask you to reconsider. Most people I know would agree that once you start grinding your own you can never go back to (even one day old) pre-ground.
It is important to get a conical burr grinder. Yes, they're the '3rd' tier in terms of price, but through the years I've had blade and regular burr grinders and I can definitely say that the one I have now makes quite noticeably better coffee. The difference is in the consistency of the grind. Different brewing methods require different grind sizes and when the grains are all different sizes you don't get the benefits of the particular type of brew. For instance cappuccino requires that no large grains be present because they'll form channels in the 'puck' which allow steam to pass through too quickly. Similarly a drip process requires that no super-pulverized 'coffee dust' be present as this leads to bitterness.
French pressed coffee is currently my favorite brewing method. I used to use a hario hand grinder but it was tough to dial it in and required a lot of elbow grease.
I upgraded to a baratza encore and am pretty happy with it. It cost me $130 and I definitely noticed a difference in taste. My ideal coffee grind setting for this is 28.
The coffee to water ratio I have been using is: 30g coffee to 450g water for a 16oz travel mug and 50g coffee to 800g water to make a full 32oz sized bodum french press. *adjust to taste of course! :)
I actually recorded my process here, so please critique or let me know if you have any tips/advice to add, thx!
