Coffee Brewing Ratios Explained

How much coffee should you use per cup? This is a dive into coffee brewing ratios, recipes and a little bit of coffee brewing theory.

James is one of the few youtubers that has useful content in a good format. He’s not shouting at you, he’s not stalling the video just to make it longer. The background music is light, the editing is minimal. A pleasure to watch!

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.

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.

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.

James Hoffmann
you give information.
you teach fundamentals.
and you make people to forget them and search for their taste. You are a next generation teacher. Thanks.

For my photography buddies:
grind = ISO
ratio = aperture
extraction = shutter time
strength = exposure
taste = sensor color accuracy

I love this guys personality he comes across as humble yet snooty at the same time

A coffee nerd who happens to explain well and articulate, with hundreds of videos dedicated to different methods of making coffee. That's what I needed.

I use approximately 20 yottadaltons of coffee per cubic metre (under 133 torr of atmosphere, of course).

"Grams per ounce...get out" earned a like and subscription from me (along with James' perfect blend of humor and exact science). As usual, great video.

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!

I feel smarter listening to James even though I understand almost nothing 😂

And to think all these years I’ve been using barleycorns per hogshead.

I haven’t slept since Thatcher was in office.

im thinking 1 handful of beans and one handful of water

I've gained so much knowledge from James's videos. The biggest takeaway is that numerous factors influence the taste of coffee, but personal preference is what truly matters. Now, I feel confident experimenting to find what suits my taste best. Thanks a lot, James!

It’s nice to know there are analytical, precise people out there getting things solved for the rest of us.

As someone who has only bought coffee at shops, used a pod coffee machine, and just bought a french press to actually make my own coffee at home for the first time, this advice on where to start is very helpful

[trumpyone]

There’s something about the way James talks, his quiet manner and yet still explaining a complex subject that make his videos very enjoyable. Plus I’m making better espresso at the end of the day.
