A brief history of instant coffee
MikeTheGreat: Thanks for posting this!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.Thanks for posting it! :)
firefax: 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
AlBugdy: 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.
TRiG_Ireland: The UK is not an outlier here. Much of the world has the same voltage.
mikestew: U. K. 240v vs. 120v in the U. S., twice the voltage == twice the amperage == 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].[0] https://improbable.com/2018/10/26/a-look-back-at-george-gobl...

AlBugdy: 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.
maxbond: 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 (though not particularly likely) 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 should all come off.
softbuilder: Twice the voltage == half the amperage for the same wattage. Are UK kettles higher wattage?
mathgeek: 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.
hysan: 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.
jemmyw: 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.
TacticalCoder: > ... and the mix of ingredients that doesn't trigger any refluxAh 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).P.S: I'll try your mocha trick!
marcellus23: > I drink more coffee than 99% of the populationHow much is that?
bombcar: 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.
gib444: 3000 glorious watts
throwaway27448: You can also simply keep water near boiling.
ak217: 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.
ghthor: 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.
kiddico: "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."Is my favorite part of the article lol
