Making an International Standard Cup of Tea

Published on Apr 9, 2018
As far as I can find, no-one has actually made a International Standard Cup of Tea - ISO 3103 or BS 6008 - for the internet before. Lots of people have talked about it, but that's easy. Making one? That requires precision... and some specialist equipment.

Update: someone has found an earlier ISO cup of tea on the internet, as part of a German video on tea tasting: us-tv.org/tv/video-utwwkNkNgiM.html

  • Quietly edited out of this video: two minutes of waiting for the kettle to boil because I forgot to push the button to start it.

    • Bruh.

    • Fun fact- people who drink tea with milk also eat pineapple pizzas and mix chocolate with ketchup.

    • So what about water boiled at different altitudes. Water boils at a lower temp the higher you go therefore producing differenet results.

    • "I don't like tea" I feel used, every video of yours that I've watched and every thumbs up I've given is now tainted.... how can you not like tea! I feel like you're not even English anymore! Jk!

    • Have you ever made a video over the foxton locks near liecestershire? They are a still-active canal system with hand-operated gates. It was also the site of a steam-powered boat lift before it became too expensive. I don't know what qualifies "Amazing Places" for your videos, but I think it would be an interesting one.

  • There was something wonderfully reassuring about this video

  • I don't really like tea that much either. But I'm not British so it's fine please don't sue me

  • I don't like tea I like gin

  • I drink green tea with milk. I know I don't deserve to breath...xD

  • does the standard not ask for water at a certain temperature?? or at least the same temperature per tea category?

  • Hold on there mate, I was with you until you mentioned the fact it was green tea. The only cup of tea is a Yorkshire cup of tea

  • 茶,来中国看看吧

  • I can literary smell the tea...

  • "just like that" is my favourite way to do tea, yerba or heroin injection

  • I wanted to say it's one of the most British videos ever and than you've said that you don't fancy tea...

  • Everyone is going nuts about how tom doesn't like tea mainwhile i am going nuts over the damn near ancient browser running on that library computer (it says its "chrome" in the title bar but it looks more like IE6 its so old)

  • doesn't like tea? then who's kettle is it?

  • I called that ending!

  • Cant find this video in my subscription box or my notifications

  • Sooo making tea days in advance and warming it up later isn't THE standard way to make tea??

  • Tea is serious business.

  • I have my own unique special ritual for making the perfect most wholesome tea ever! Let's just say raw ginger is involved ;)

  • that is how Tom lost his british citizenship. pha, not liking tea!

  • My grandfather literally boils the tea (water with tea leaves in it) for 10 minutes! I tried reporting him to _the International Court of What the Hell are you Doing_ to no avail...

  • Half as Intersting

  • Don't like tea? That's because you've been drinking that british crap your whole life, you need some good ol' U-S-of-A southern iced tea my friend.

  • I’m from the southeast United States. Tea for me is like half sugar, if not more. The sweeter the better :)

  • Neither do I Tom. :P

  • So basically this is the forerunner of the Nutri-Matic Machine from HHGTTG: a machine that makes a drink that isn't meant to be the best cup of tea, but just something Okay, something that wherever you are in the Galaxy, you can rely on to be standardized and normal. Like a McDonald's meal. Share and enjoy!

  • Is there an american standard? Where there is ice and sugar involved?

  • “I don’t actually like tea!” 🤨🤔 *unsubscribes*

  • daddy

  • *Whole comment section explodes about tea comment* Me: Has no-one watched the Parkbench about controversial opinions? Okay.

  • This channel is so wholesome

  • You look like my friend

  • Every now and then I forget about this channel for a few weeks and have the privilege of binging all the video's I missed. They're amazingly informative, and not just stuck in one concept that gets boring after a while. Often I've clicked on a video thinking 'well this won't tickle my intrest' only really feel I've learned something I never wanted, but strangely cant live without anymore. I've rarely seen a channel that brings information in such a clear, understandable way while its accompanied with great camera shots and editing. Not to mention the soothing voice that is just great for late nights when I need to wind down a bit. Tom, I absolutely love these videos, and all the time you (and matt) put in. (as a sidenote I also love the humor between the two of you on the not-so-park-benches.) If you're ever in holland, let me know and you'll have a place to stay for free.

  • Correct me if I'm wrong but hasn't matt Parker from standupmaths done this before?

  • I like the fact that this is actually a thing. I wonder how this equipment is calibrated. Surely there has to be a standard for that too!

  • Half as Interesting also has a video on this. Huh...

  • I have that kettle, highest rated kettle on amazon

  • There should be concentration camps for people that drink un-standardized tea

  • Glad to see I’m not the only person to reuse the Gü dessert ramekins!

  • I pressure cook my tea. That absolutely extracts the most out of the leaves.

  • The next video is your video about the most famous teapot.

  • Nah, all of this work and equipment, this ain't my cup of tea.

  • "I don't like tea" WHAT ? Unsuscribed !!!!!!. (I'm joking, in case someone would take me seriously)

  • "I don't actually like tea." Scott you slay me.

  • "I don't actually like tea." All of England was in an uproar that evening.

  • The literature that is ISO 3103 won an Ig Nobel Prize (a satirical Nobel Prize) that are "unusual or trivial achievements in scientific research".

  • Now time to microwave tea for the internet.

  • @Tom Have you tried Bubble Tea? I have no idea if you will like it, but the Taiwanese style one is reallly good, and you have some good examples around London.

  • Nice guu jars

  • Misunderstandard

  • Wow I thought you olnly in computer phile :)

  • I main Camille in League of Legends. My username is "EinCamillenTee" (german for "ACamilleTea")

  • If the standard exists so that people can make a reproducible cup of tea, does this mean that many other people should make similar videos? Reproducibility is an important part of science, after all.

  • When Tom tasted the tea I thought for a moment that he gonna joke "Well, it taste like tea".

  • Heh, funny. I never thought about how english speakers would call "Normen." I would have said norms, turns out it's standard.

  • Okay, but why are people so shocked that he doesn't like tea?

  • 310,400 views & 17k likes in 3 days: doing all right there, Tom. More power to you.

  • The things you will do for the internet! Wasn't the cold? Or at least lukewarm? 6 mins is a long time to be seeping a cup of tea!

  • well Tea bags already follow a standard, since beside the brew time on the box, the amount inside the bag is already measured, and the bag does the straining for you, just a different mechanism

  • ISO standard for tea... Because someone has no life..

  • why o why i cannot see here famous tea quote (standard i guess): "almost but not entirely unlike tea" :D

  • “...I don’t actually like tea.”

  • Then... Coffee?

  • Centralia Pennsylvania u should google it and maybe go there

  • “That whoever and wherever you are, you can create this” ...but you said you need access to the standard and that you also need access to specialized equipment...

  • Am I going crazy or is his shirt changing colour when I hover over the video

  • What is this 😂 who takes tea this seriously

  • Mmmm tea😋

  • Isn’t milk before the tea the origin of the term mift, wich usually isn’t associated with anything positive?

  • Isn't it mandatory for any Britt to like tea?

  • Teabag, *then milk,* then boiling water. Don't leave it to brew, just swirl it with a spoon and then press the teabag up against the side of the mug to squeeze out some more flavour. Come at me. No sugar either, but that isn't very controversial.

  • Is he legally allowed to say that thing at the end, that I will not repeat, in the UK?

  • Forget like for dislike, slurping drinks is unforgivable.

  • Milk in tea? That's weird haha! 💛💙💜

  • Casually dropping that bombshell at the end!

  • What? Nothing about the exact temperature?

  • « I do t actually like tea » Made three videos about tea on two different continents

  • Boring subject, no background music, I'm not a tea drinker, the video wasn't full of hilarity, and the subject has been talked about to death already....yet somehow I still manage to watch and thoroughly enjoy. How do you do that?

  • Hey now, I occasionally microwave my tea! Leafs + cold water in a cup, ~2,5 minutes in the microwave and then filter it.

  • The taste of the tea leaves will drift over time. They need to specify the genome too. I guess then it'll become the most inaccessible recipe as well, but it will be precise.

  • Wait British and you don't "actually like tea" juicy scandal!

  • Can do cover ISO 1839 in other video down the track? Love your work

  • It must be a punishable offence to not use black tea in the demonstration

  • what should be temperature of the water

  • There was a tea add at the start of the video.

  • half as interesting as on the half as interesting

  • Watching this whole drinking Boh tea.

  • I remember having seen a video wehre they made one... but it was years ago and probably part of some larger video (not a dedicated ISO3103 one)... Nevertheless, I think your phrasing kind of misses, or missguides, the real point of a process like this. Yes, it is meant to be a standard, but since it involves a very, very variable agricultural product like tea, it will be almos 100% impossible to "make the same cup of tea every time and regardless of where you are (etc.)". The real point of the whole thing is to be able to compare different tea samples agains each other under standardized conditions; to eliminate any other variable that's not the tea itself. So, of course you will get wildly different teas from this years and last years harvest, no matter how close you adhere to ISO30103; but that's the point... only, that you will know exactly that the difference comes from the leaves and no other factor. The only way to get as close as possible to getting the "same" cup every time, would be to use the exact same batch of tea leaves; and even so, it's probable that leave size and other small and impossible to controll things, would make it just a 99% match (not that many people would notice anyway). And, please, don't get me wrong... your video is superb and your explanation generally ok. I just think that the real aim of the standard wasn't as well explained as the rest of it.

  • What! A British person who DOESN’T LIKE TEA! that’s practically a federal offence in England

  • I’m sorry sir you are going to have to take that back or your British citizenship will be taken away within the hour.

  • 100 ml before or after heating?

  • I drink loose tea, quite a fan of Assam.

  • Doing it that way doesn’t actually taste any better than literally microwaving water with a teabag in it, why does anyone think it’s supposed to be the ideal cup of tea?

  • Now you have to make a video and coffee. I would love to know the perfect Tom Scott cup of coffee.

  • N_N

  • I never knew there was a standard for tea!

  • The gaiwan should be the standard vessel for tea brewing.

  • Non-tea-drinking American here: what is the purpose of an international standard for tea? Like, who benefits from this, and what is it used for? I'm not against tea in any way, I've just never had any, and am all the more confused as to why one would desire for there to be a standard for... tea. Is there an international standard for sandwiches?

  • Try indian tea aka chai

  • Liqor - pronounced lie-core, I believe. Not like the booze

  • The best, standard cup of tea is sadly no longer available. It died the day that British Rail was privatised. BR tea may you rest in peace.
