It's unfortunate that instant coffee has such as a bad reputation in the US. In Australia, instant coffee is very common; it's pretty good.
I would much prefer a cup of instant coffee to most coffee that is served at diners, brunch/lunch restaurants, etc. in the US. I prefer espresso still, but there's a lot of burnt tasting coffee in America.
I started using instant coffee in hot chocolate as a quick DIY mocha, mainly because the cost-caffeine ratio was sooooo much better than beans (ground or whole) and the mix of ingredients that doesn't trigger any reflux (unlike the 400 mg / serving powdered energy drink I had been guzzling).
Which is to say - this is a fun and interesting article about something I had just been taking for granted. It's really neat to learn about the trials and tribulations that folks went through to figure it out.
> ... and the mix of ingredients that doesn't trigger any reflux
Ah reflux! I drink way too much coffee since forever and recently asked my doc about it: he told me that if I had no reflux, then I simply shouldn't worry about it. Some people have reflux with coffee, others don't. I drink more coffee than 99% of the population and I get zero reflux. Since decades.
It's a cool article but in a way many coffee became instant coffee: as my coffee machine is often already warm (wife btw she's also a heavy coffee drinker), it's actually more instant to have my full auto coffee machine ground the beans and make a coffee than it'd take to boil water for an instant coffee. Same for the people doing the (very costly compared to beans) capsule coffee thing: it's ultra quick (and one of the reason capsule coffee like Nespresso conquered so many).
"I am very happy despite the rats, the rain, the mud, the draughts, the roar of the cannon and the scream of shells. It takes only a minute to light my little oil heater and make some George Washington Coffee . . . Every night I offer up a special petition to the health and well-being of Mr. Washington."
> which is why spray drying remains the dominant method
I don't think I've ever seen spray-dried. Even the cheap supermarket instant coffee is mostly freeze-dried in the UK I believe.
You can really see the power of marketing at play in instant coffee.
A lot of 'premium' branded instant coffee is ~£42/kg. That's £3/kg more than my premium, locally-roasted, single-estate Colombian coffee beans.
If you have more money than sense, there's even "Nescafe Gold Blend Cap Colombia" at £62/kg
I do drink instant, but I stick to supermarket own-brand 'gold' that is around £13-18/kg (freeze dried). You just accept it'll be bad, and always drink with sugar and milk.
I find the basic Nescafe has a distinct taste and not in a good way. I think a lot of people buy it for nostalgic reasons and not much else (well, excluding the brain-dead brand addicts)
> A lot of 'premium' branded instant coffee is ~£42/kg. That's £3/kg more than my premium, locally-roasted, single-estate Colombian coffee beans.
That weight comparison doesn't make sense. How many cups of coffee do you get from your beans versus the instant? I just checked the jar I have here for my lazy weekends, it's ~2g per cup of coffee (rounding up, it's a bit under 200g and it makes about 100 cups). So a kg of instant would be around 500 cups of coffee. I don't think your 1kg of beans will produce that many cups.
In terms of the volume of the final beverage, 1kg of instant coffee goes a lot further than 1kg of whole bean coffee does.
I don't measure coffee by weight when making the stuff (I use the eyebolic method with the coffee grinder, and the equally-imprecise heaping spoonful method with instant), but some homework suggests that it takes ~60g of whole bean coffee, or ~9g of instant coffee, to produce 1 liter of beverage.
If a cup holds 300ml (as the normal US-centric one I picked from my cabinet does), then when we use your prices we get:
~£0.702 per cup from premium, locally-roasted, single-estate Columbia coffee beans
~£0.1134 per cup from 'premium' instant coffee.
...which makes instant a whole heckuva lot less expensive to drink. :)
> A lot of 'premium' branded instant coffee is ~£42/kg. That's £3/kg more than my premium, locally-roasted, single-estate Colombian coffee beans.
You need 7-10 times less instant coffee to make a cup though, so your beans are a lot more expensive in the end. From my experience, cup of coffee is either 2 grams of Nescafe Gold or 16 grams of beans.
it's never instant because boiling water takes sooooo longgggg. apparently uk teakettles are faster due to voltage differences? i want to look for a usb-c solution sometime
The good news is that boiling water is not functionally necessary since the extraction was done up front. I drink it cold or with warm water. Boiling is hotter than I want to drink anyway.
If there's significant scale at the bottom it's possible it's making your kettle materially less efficient. If you put in like a cup of vinegar and a cup of water (you could probably dilute it more than that), heat it up and swish it around (it doesn't need to be boiling), it should all come off.
Indeed. I have a Nespresso machine for when I need coffee quickly. As soon as I press the button, hot water flows in a trickle. It’s certainly not boiling but it’s an ideal temperature as a hot drink.
USB-C PD has far lower wattage than the wall outlet anywhere in the world. Now I want someone to build a kettle that accepts a J1772 connection (for charging electric vehicles). That’s nowadays more common than any 240V NEMA outlets.
U. K. 240v vs. 120v in the U. S., twice the voltage == twice the amperage (EDIT: oops, wattage, for the same amps) == half the time to boiling. I will note that doubling the voltage will still not make it "instant". For that I think you need liquid oxygen[0].
Does it? It only takes like 2 min for my electric kettle to boil. If I was a more avid coffee/tea drinker, I’d get one of the always heated hot water dispensers that are common in Japanese households (def one of the appliances I miss since moving back to the US). Then you never have to wait.
In electric kettles or a microwave or even in a moka pot or another small container on a decent induction stove it's just 2-3 minutes. There was a video I can't find where they increased the voltage or something for a kettle and at one point it boiled the water in like 10-15 seconds.
It was another, shorter video, not by TC. Just different voltages (or maybe there were other variables) one after the other until the water boiled really quickly and afterwards the kettle blew a fuse or broke (can't remember).
I guess many people have tried doing something like this. But I'll watch TC's video, too - he hasn't disappointed me so far.
Edit: Watched it. Not the same video, but this one had a lot more info and troubleshooting than what the one I had in mind.
For real instant: install a hot water tap. It has a small boiler under the sink that keeps the water at near boiling. I've got one and it's great - instant tea any time.
Of all the things I have cooked on my induction cooktops over the years, boiling water fast is what I miss when I travel and have to use electric coils.
I'm in the UK but I have a kettle that lets you pick the temperature. I usually just use 50C (122F) for instant if I'm having it black, or 70C (158F) for a splash of milk. Boiling water would make an already miserable experience far more miserable.
If you’re brewing from ground you really don’t want boiling 212F water as you’ll burn the grounds. I do my pour over at 185F and get smooth ready to drink hot coffee with no/low acidity.

How much is that?

This guy (sunshine) designed a 3d-printed mocha pot that boils in half the time over a flame. https://www.youtube.com/watch?v=LuZiqLb70tM

Twice the voltage == half the amperage for the same wattage. Are UK kettles higher wattage?
Actually yes, around double the wattage. It's one of the things English people notice when they move to the US (true!).
US circuits are about 15 amps; UK ones similar - but twice the volts.
So a US kettle is about 1500 watts, a UK one 3000.
You can get commercial water boilers in the US if you need.
3000 glorious watts
You can also simply keep water near boiling.
All the time? That's very inefficient, especially when running your boiler outside heating season and without a vacuum flask.
The actual solution is to boil small quantities of water. I can boil one cup in 90 seconds or so, even with the 120v handicap.
Sure, but efficiency wasn't the goal here. Anyway I use hot water enough (~6-10 times daily) that I don't mind spending extra for it
Does it? It only takes like 2 min for my electric kettle to boil. If I was a more avid coffee/tea drinker, I’d get one of the always heated hot water dispensers that are common in Japanese households (def one of the appliances I miss since moving back to the US). Then you never have to wait.
I just use the microwave TBH. 60s and done.
My completely unremarkable microwave is rated at 1800W whereas my unremarkable electric kettle is rated at 1200W.
In electric kettles or a microwave or even in a moka pot or another small container on a decent induction stove it's just 2-3 minutes. There was a video I can't find where they increased the voltage or something for a kettle and at one point it boiled the water in like 10-15 seconds.
Technology Connections?

I considered this when I rebuilt my kitchen last year but the price was obscene - starting at $1600 AUD installed.
I bought one of these for $79 instead and I’ve been perfectly happy with it.
