Because of randomly stumbling upon this channel, in a week I went from drinking maybe a cup of coffee a week to buying $200 in equipment and weighing coffee to the gram and grinding it to perfection. If anything, the stay at home coronavirus order has caused me to become a bit more cultured.

[@hxhdfjifzirstc894]

I live from at least one level below 'culture', currently (perhaps you could call it 'soldier'), but still above 'animal'. It's commendable that you have found an opportunity to improve yourself, however a truly cultured man would avoid such a 'low' topic of conversation as 'Muh virus'. Don't confuse the trappings of herd animals with [high] culture, whether coffee, or corona. For some it might be necessary to forge your own path into 'culture', if you are able. Challenge: Begin with Black Label, neat... and Duke Ellington. Learn to love it because it's good, not so that you can impress granny on Facebook. Only one tip, and it should be obvious. It must be almost dark in the room when you listen to jazz, in order to hear it most clearly.

[@lukasplatz]

I think the reason the percolation brews produce stronger coffee is because of saturation effects rather than the amount of final product over which the dissolved coffee contents are distributed: in both cases the coffee will absorb the same amount of liquid. What is different between the two methods is that during percolation brewing the coffee contents that go into solution are continously washed away by the water flowing through, so the coffee grounds are always surrounded by "unloaded" water, white in the infusion brew, the coffee is surrounded by water already loaded with dissolved coffee contents, reducing the rate of dissolution. This effect is actually used in chemistry labs: it is far more efficient (solvent-wise) to wash glassware multiple times with small amounts of solvent than once with the same total amount.

[@supme7558]

It has to do with how long the water and grounds are in contact just like tea so if it is a slower perc better coffee water just drios through quick its week

[@dougfreeman3229]

Watch the video again. As James says, for percolation more water is left in the filter and grounds, thus less liquid coffee vs immersion. It's irrelevant anyway - brew to the strength you want.

Putting aside the excellent coffee knowledge gained from watching James' videos, this one has my favorite rant (3:20) the mixed unit ratio. Thank you for making all of our coffee brewing better and for the humor.

@@Jung_Tae_Hun I take great pride in my analogy :) ISO - "sensitivity" in analog photography, digital gain in digital photography; it determines the Signal to Noise Ratio (SNR), thus the noisy grain of the image in low light for high values; Aperture - How wide open is you lens; Shutter time - how much time you let the light go through your open lens; Exposure - A subjective estimation of the overall quantity of light; you can expose correctly for the highlights details (less light needed) or for the details in the dark areas / shadows (more light needed), a choice of point of interest, or simply a matter of preference; Color accuracy - depends on the design, HW manufacturer and technology generation (and the Bayer patterns demosaic algorithms).

James. I'm nearly 70 and you have made me realize I've been coffeeing incorrectly for all of my life so far. So I am restarting my journey at this late stage! I use a French press. First off, I have been using a cheap blade grinder for my medium roast beans ..... oh what a mistake. I do however weigh / measure my coffee beans and use the same time of grind (bashing / slashing) each time. So I have been getting consistent (ly bad?) results! I've noticed a fair bit of "mud" at the bottom of my cup. Shortening blade slashing time results in coarser grind, but not such great coffee. So I'm researching burr grinders. I think I'll plump for the tank - Kinu M47. Then I've only just realized, I thought I was using 60g/l, but my French press is 1 liter (not 500 ml) so in fact the coffee is 30 g/l strength. Putting 60 g of beans into my blade slasher overwhelmed it - and the resulting coffee was again muddy and too strong for me. I will experiment some more when I get a proper grinder. Please forgive me if I go significantly less than 60g/l !!! Really enjoy your videos. Thanks for entertaining / instructing us!

[@Bill_CBR]

So, it's been a year since your comment. Did you get a burr grinder? How many grams per liter are you using now? I too use a FP and it seems by this video that I'm using too little coffee as well. So, just curious where you've ended up.

I found this video by mistake while searching for something else. I am a tea drinker mostly, but do quite like a milk based coffee - maybe 1 cup per day in the afternoon as a bit of indulgence, but using a moka pot I could never get the ratio correct, and often over boiled it , burning it, so resorted to just hot milk with instant coffee as I just couldnt get it right. I have now watched a lot of James videos and have enjoyed a latte or cappacino daily....I still use only a moka pot, it's nice and hot but not burned, and also very tasty coffee which is just the right strength for my particular taste. Having watched his video on types of coffee, I even know which coffee is best for my taste. I am still buying ground coffee, but my next plan is to buy coffee beans and a coffee grinder - fun times! James is clear and concise, a good video to watch. Thank you.

@@kgehmlich it's the worst because ordering a pint you never know if you're getting a US or imperial pint, it's like 100 ml difference! Tall boys are American pints. 473 ml = US pint, 568 = imperial pint. They might just give you 500 ml and call it good, I've seen Guinness in 473 and 500 cans (don't do the vertical pour of a 500 ml can into the 473 tailored glass...) Also for baking watch your measures and your recipe. US customary units are not imperial units for size. New measures sold in stores are in US units in cups and spoons but grandma's old measuring tools are in imperial. Her old recipes are in imperial and new recipes are probably in US customary. 1 US cup = 8 US fluid ounces = 9.6 imperial fluid ounces. An imperial cup = 10 imperial fluid ounces. Fluid ounce difference also matters with hard liquor.

[@mastley3]

I agree with the conclusion (immersion methods require more coffee per liter), but I disagree on how you get there James. Are you saying that if you make a liter of French press that your output is 1000 ml of beverage? That seems unlikely. Isn't it more likely that in any method, some water becomes saturated as it dissolves coffee that it is in contact with? In a pour over, that saturated water drops through and is replaced by "fresh" water that is ready to dissolve more chemical compounds? Immersion methods extract more slowly as the water becomes more saturated. That's why the famous Hoffman Method for French press works so well! By the way, I'm V60 pourover at 15:1. If I add 30 ml more at the end of that, the result is bitter and generally dull, though with some Kenyans, that last 30 ml is tasty and gets added into the overall brew.

I've changed my method of brewing over time, but only slightly. I started off, as many do, with a drip style percolating machine. I then moved to a K-cup, but it never seemed strong enough. Then I moved to a old style percolator like what you'd find on a stovetop, but the first one I used was electric (old Pyrex coffee percolator on a stove is what I use most now), and that is my preferred method nowadays. It makes some amazing coffee. It may not be for everyone but it's a ton better than the methods mentioned in this post. I have a ratio right now that works and a brewing method I like. Not sure I want to mess with it at this point, but I may need to tweak it with what you mentioned in this video.

[@jaymerryfield]

Apologies if I missed this question having been asked previously in the nearly thousand or so comments made below this one, but I do have a quick question for you James: If 2g of water is absorbed per gram of coffee in a percolation brew, resulting in only 880ml of finished coffee available after starting your brew with 1L of water, why would coffee brewed with an inversion method not also absorb a similar amount of water from your initial brew weight, therefore similarly being unavailable for drinking after the fact? I wouldn't imagine the effect of pressing your coffee would extract more water from the grounds than would allowing a nice full draw down in a pour-over. Thanks for the videos, and for taking questions! I'm still learning on my coffee journey, but over the last year my morning cup has improved IMMENSELY as has my overall enjoyment of coffee culture, a large part of both relating to the content you create. :)

[@cho4d]

i agree. frankly, i would say MORE water is left over in a french press. if you squeeze it all out you're going to get tons of grounds in your drink. i think the real difference is that pure water is a more potent solvent than coffee water. in immersion the power of the solvent goes down as the brew progresses. in percolation you are constantly changing out the "spent" water and replacing it with pure water ready to extract at full potential.

[@postscript3150]

[@Hangingofgiants]

I've always worked 1/waterever ratio.. However your explanation as to why grams per litre makes a lot of sense. Might have to try converting my ratios over :) sometimes however I just have fir example 17grams left in the bag and simply multiplying by 15 or 16 is an easy way to finish it off.

[@happymeeple5146]

Good brew ratio for me brewing V60/Chemex turns out to be: Light-Medium/Modern Roasts: about 65gr/L and medium-dark/more classic roasts: about 60gr/L. But it is really individual on each coffee. Once dialed in and a (grind) setting for delicious tasting coffee is found, I set the brew ratio to the strength which fits best to the character of the coffee. But in general the above mentioned settings will work for me mostly. More gets so dense, that it tastes thick and a bit soapy and less is to watery. All of this is quite some work, but also fun though 😏 ☕️ Another very interesting topic is the time/grind setting. This is much more complex. As the extraction changes with grind setting as well. Coarser takes longer to extract, but passes quicker. To meet the sweetspot is not easy, especially as there are so many contributing factors: brewing device, filter paper, coffee, grind setting, pour/flow rate. And again it changes with desired amount of coffee. So far I would put it towards 2:30-3:00 for 300ml on a V60. And 3:30-4:00 for 500ml on a Chemex. Including a 30sec blooming. What do you guys think? Maybe a good Topic for another video 😉

[@andrewfurusawa4609]

I totally agree, there are so many other factors that brewing ratio is only one small tool to actually making a good cup. Coffee freshness, type, quality, grind size are all such huge factors that drastically change the ratio.

[@sassak]

g / oz (liquid) works for me but I'm in the US. This may have already been posted but who cares : for those wanting the 60g coffee / 1 liter water changed into cups or liquid ounces -- 60g coffee per 33.8 liquid ounces -- 60g per 4.225 cups water -- 14.2g per cup water -- 1.775g per liquid ounce of water -- 60 grams is about equal to 2.116 ounces (mass) so then it would be 2.116 oz per 33.8 oz :) American ratios use grams coffee / cup or oz liquid because grams displays in nice whole numbers on our scales, but our measuring cups always have oz/cups, even though larger ones tend to also have metric units displayed either on the same chart, or on the opposite side of the measuring cup.

Coffee making is a science. My cup of filtered coffee wouldn‘t suit everyone as someone else’s coffee wouldn’t necessarily suit me.

I absolutely LOVE your videos, bro! I’ve been experimenting with both pour over and French press brewing methods and this video gave me something to think about, seriously. To date, I prefer the French press over the pour over and drip coffee brewing methods. My coffee has tasted consistently and significantly better IMO. I’m going to try the 75g/liter method you mentioned and see how it compares to how I’ve been brewing (16:1 method). Thanks, as always for the fab content!

[@peterwhyte317]

Thanks for your logical presentation. My comment is that the "woody" stuff that you mention usually floats to the surface in the plunger, even when I have stirred the mixture after adding the water. This acts as an effective filter bed, whereas lots of mud gets through the plunger gauze if you stir the brew again. Also I plunge SLOWLY.

I wish this wouldn't have ended, this is so, so good! Please do more videos about extraction theories and the different factors affecting the solubility. I used to brew with 55g/1l, but gradually, I've realised I prefer something more between 60g-65g/l. But I still have trouble with brewing times for different roast profiles; light roasts tend to take me a longer brewing time than darker ones, and I have no idea why. Thank you for the video, James, this is brilliant stuff.

[@Dims338003]

light roasted coffee is less soluble, water struggles more to get in and out the particles of ground coffee

[@gabriel_export]

I've noticed this too. I think it has something to do with the density of the bean and how that deals with water retention. Lightly Roasted beans are typically more dense than darkly Roasted beans. Not really sure though. Like since they are more dense there is more surface area making the flow rate slower and dark roasts have less surface area, more air, and less density.

[@AnayMridul]

@@Dims338003 That makes a lot of sense! It's weird though, because I always get a 2:30 brewing time for medium to dark roasts on a V60, but light roasts almost never finish before 3:15.

[@AnayMridul]

@@gabriel_export That's some really good insight, thanks! Are you saying it's more about density than solubility? How do your brewing times differ?

[@gabriel_export]

@@AnayMridul Not really sure the exact science but I should research it! Light roasts always have a slower flow rate and hence a longer brew time than darker roasts. You're not alone! I normally just adjust my pour speed and it accounts for the time diff for the most part.

Excellent video James. When I was younger, I liked really strong, dark roast coffee. That started because I got to try some espresso and coffee from Italy. I got back and everything tasted weak and light. As I get older (i'm almost 40 now), I like a medium strength coffee. Sometimes dark, sometimes medium. I've also restricted the amount of coffee I drink now as I was a little bit TOO on edge. I drink, at most 3 cups in a day. Most days, I have 1 or 2 cups.

I want you to meet my dad. In his world one cup of coffee has to consist of one spoon of preground. doesn't matter what spoon. no need to weigh anything because he just wants to make coffee and he's not a scientist. cups are measured by the scale on the water tank of the drip brewer not by the actual cup he uses. coarseness dosn't matter because he can just buy preground coffee and who has time to grind coffee in the morning anyways? also there is no such thing as brewtime. the coffee is done when all of the water went into the pot obviously.

I played this at 2x speed and part way through thought to myself: "this man has had too much caffeine."

[@pentecost_]

Totally understand your stance on grams per litre. I can see how that can simplify things for some individuals. However, I've started with and stuck with my usual 1:16 ratio (15g coffee to 240g water) for my morning cup every single day. It has already become a routine/habit. Tried changing the ratios (1:13, 1:15, 1:17) and it has just never felt right. It all comes down to personal preference and I have found what works best for me over the years.

[@tom-gnade]

James you have a real talent for teaching, great video. I use a Yama siphon every morning - I don't use scales, I just eyeball the water level and use 5 or 5.5 scoops of whole bean coffee that I grind using a Krups blade grinder (will upgrade soon). I measured it once at 1150mL water and 65g ground coffee, so it's a little over 17:1 ratio. Since I'm brewing for both me and my wife, she likes slightly less potent coffee, and I've found my own preference has aligned with that now - I actually think it tastes better at this strength. Anyhow, I use the finest grind that my metal filter will allow without a stuck filtration in the siphon, and 50 seconds immersion time before I remove from the heat for the draw-down. After watching some of your videos and researching the bloom a bit, I've now added a bloom step - I use a glass measuring cup and steep the grinds in just enough water to cover them for 30-45 seconds just before I add them to the siphon, and it makes a distinct and considerable improvement. The resulting coffee is as good as I've ever been able to brew. While I'm sure there's plenty of room to improve still, I can tell you that my wife thinks any other coffee is gross, and her friends come visit us sometimes just to have my coffee. :-) Will buy an Ode or Niche soon to step up my game. Love the videos, please keep making content, you are a natural.

[@philiphand9539]

James, as always - another spot on 'brilliant' Video... Couple of things that interesting here: 1. The establishment of a water 'recipe' to start. Having the 'desired' TDS (80-120) and Hardness 1-2 grains, is a critical part of getting to the finish line with a very desirable cup. This is the SCA Gold Cup recipe, and one that is very spot on - in terms of water quality with respect to all forms of Extraction. 2. If the above water recipe isn't available for people, then they will have to actually use MORE coffee than is normally required, as their 'Total Dissolved Solids' (the Mineral bits) are usually higher and will fight the strength of the coffee...This will be common in water in the UK and throughout Europe and many parts of the U.S. 2. I use a 'multiplier' - based on this 'Gold Cup' standard - which happens to be the same as your desired amount. It's simply this: use .06 as the multiplier for ANY amount of coffee to be brewed. For instance, if we say that 1 liter is 1000 ml, I would use your 60 grams ratio (multiplying 1000ml by .06) to come up with the amount of coffee to use. While you already know this, it's helpful for many who have small Coffee pots for their coffee makers to measure how much water they can brew, to determine how much coffee they need. Sorry for the rambling... LOVE YOU.. you're the BEST!

Hey James, I watch a ton of your videos and I love the passion you put into what you do. In the beginning I was a Mr. coffee percolator kind a guy. Then I went to a French press and it got even better. Now I use a Chemex and I love it. My son knows I love coffee and he got me an aero press. Now my whole world is changing again. I am the 30 grams of coffee to 450 grams of coffee. And 205° water “pure” 3X the water for the coffee bloom (30=90) a 30 second bloom and a 3 minute extraction. Now I am rethinking things ( this is all for the Chemex ). I also love my aero press, nothing elegant there but it does produce a good cup of coffee. But now I will play with the brew time water temperature and stirring gently and swirling. I like the not having to think in the morning the 30 gs of coffee per liter of water lol! Any advice or comments would be welcome and again thanks for all that you do👍

[@heatherdouglas-palumberi8297]

Thank you very much for making this video! We just purchased a commercial BUNN VP17 SS, using a SS funnel and tip kit for home use. Used 12oz decanter. Created a recipe with your 1L to 60g and tweaked to 62g, because the first brew was very good, but had slightly less oomph than we desired. Tim Horton whole beans utilized, ground to medium/a bit more to the finer side. Used basic Krups grinder. BUNN heats to 200 degrees F, using gravity as function. Ours requires addition of cold water at top, as is not plumbed. Wanted to share our experience in the US with your expertise, as we are very grateful! Really enjoying your channel!

In regards to the 1:15 type of ratio, I don't think most people do the math on that every morning. Having used that type of ratio for years, I figured the recipes early on and wrote them down so that I wouldn't have to labor over the math in the mornings. That being said, you may have converted me to g/l.

[@bobmack4524]

Don't hate on me BUT ... I use 13.5 grams of whole beans then grind them fine. I use 13 (get ready) fluid ounces of water. The amount of water is the constant (fills my preferred coffee cup perfectly). If I try a different type of coffee, I adjust the grams of whole beans. Again, the volume of water remains constant. As long as 1 of the 2 variables is always the same (assuming the same grind time, etc.), then I only have to adjust 1 variable to make it stronger or weaker. If I want to make more than one cup in the same brew, I double everything. I never, ever make a fraction of a cup of coffee. Also, I use the same 4 cup drip coffee maker every day. And I have checked the temperature of the water as it comes out of the reservoir and it is always 1909 deg F. Your videos are always on point. Good work.

[@krazmokramer]

Well, I'm back for a third comment. I know I'm going to get lots of negativity, but here goes. After years of using a moka pot, I recently purchased a 1950s Pyrex Flameware Percolator. I'm old now so this was for the nostalgia factor, not for "great coffee." The nostalgia adds to my perception of a great morning cup of coffee, even if the actual coffee isn't as good as it could be with newer brewing techniques. I have been playing around with the grind size, coffee quantity and length of brewing time. I have been keeping the coffee/water ratio constant while I adjust the grind size and brew time. I'm actually zeroing in on a decent brew. This video, and the many times I have re-watched it, have enabled me to hunt down my ideal brew in a logical and organized manner. THANK YOU, JAMES!

[@derekvalenti6912]

Thanks man! I actually understand the brewing process a bit more now, and the difference between different types of methods (immersion vs. percolation) and how the strength of coffee is dependent upon these methods, the amount of coffee used, and the coarseness of the coffee as well. Many variables! Your videos are awesome man! Keep up the great work! See ya next time!
