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.

    • well understandable considering you don't actually like tea....

    • isn't this also used to best compare different tea ingredients with each other?

    • Tom Scott If only you knew how many times that happens to me PER DAY (I really like tea.)

    • Bruh.

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

  • Hmm i guess u should come to india To make a not standard but traditional tea which i swear will b the best of ur life ever...☺😊

  • Keurigs do a damn fine job of heating up the water. Don't use the pods, though, they're expensive and pointless.

  • I do not remember to have ever come across a video featuring quite literally only comments which somehow incidentally confirm that the clip has actually been watched up to the very last second... kudos! ...even tho you actually don't like tea.

  • Anarchy in the UK: Tom doesn't like tea.

  • You make some of the most interesting videos on YT, yet you do not like tea??! Why, WHY??? On a side note, is this really a standardised way to way tea? Because, according to the variety of tea you are to make, water must have a correct, given temperature. For instance, you must not use boiling water to brew green tea because you will burn the leaves and thus, have a weird, metallic taste (there are a couple exception, some Japanese teas, like Bancha, is made using 90° water) :)

  • On the in-tea-net

  • Instruction unclear, put tea into microwave, nothing happend.

  • "I don't actually like tea." Translated: 'caauuuuusssssse Iiiiiiiiiii wannnnaaaa beeee AN-AR-CHY!!!

  • my favourite British right now doesn't like tea and the world is a lie

  • Finally! Another British person who doesn't like tea! I always get strange looks when people offer me a brew and I decline as I don't particularly like tea and I try to only drink one cup of coffee (in the morning) and water for the rest of the day. Doesn't seem like a big problem, but some people get very (VERY) offended when I refuse their offer.

  • Tea is really just diet coffee 🤨

  • Why didn't the Heart of Gold have this?

  • What about iced tea?

  • Tea is indeed a very magic thing. Even though it is embedded in a bag, it somehow affects the water and turns it into tea. Science can´t explain everything.

  • I am brazilian and I don't like coffee..

  • I do have to point out, though, that green tea is very un-British.

  • Wtf is international standard tea?

  • "I don't actually like tea" So, what do you do at tea time then? Does everyone just stair at you like the weirdo you are for not liking tae?

  • Oh god Tom, you are too good for the internet, bringing all these truths out for us. Not the hero we deserve, but certainly the one we need.

  • What the hell do you even mean by "I don't actually like tea". The British crown ordered you at the stake!

  • Wait, by uploading this, aren't you effectively republishing the ISO paper without a license? Watch your back for the ISO Police... the world's most uniformly regimented law enforcement agency.

  • "No Photography of Computer Screens" Well I see someone's a budding anarchist.

  • If you were adding milk, how much would you have added? Per amount?

  • This is the most British thing I've ever seen I love it

  • But you did it wrong... It brewed for 6 minutes and 2 seconds, not 6 minutes. I call clickbait.

  • You're wrong! Microwave tea is perfectly tasty!

  • Hahaha, the glorious UK. library running on Windows XP.

  • I notice here in the UK that its acceptable for English people to squeeze the tea bag with their fingers. I wonder if her Royal Highness likes it that way?

  • I also am not that gone on tea which in Ireland is bizarre

  • Drinking a cup of royal milk tea while watching this.

  • I wonder what the ISO is for instant coffee? :)

  • What's funny is that I have talked to some British people in the past, saying that Americans don't know anything about Tea, and that Tea in the US is bad???? I was like.... 0_o?? Um...... excuse me! But um... More Americans drink Tea than the entire population of the UK. In fact, 80% of all U.S. households will have Tea readily available in the house. Also all teas can be purchased here, just like in the UK. Then they were like yeah, but only folks in the UK really know how to make it. I was like um...Most Brits just place a tea bag in the cup/pitcher. So... >_> Nothing special at all. (As was mentioned here in this video.) Now maybe Brits drink more cups of it per day perhaps? But then again, US drink sizes also tend to be larger. In Fact the U.S. is the third largest importer of tea in the world after only Russia and Pakistan. Yeah, they did not have much to say after that. XD So I basically said yeah, you may love your tea, but that doesn't mean your the only country who drinks it.

    • "my numbers are based on science" Jesus, sounds like something from a shampoo commercial. The point I was making is the per capita is way more important than sheer volume. Maybe you need to read what I said? And well done on being technically correct that you can't assume that in comparing any two nations the one with the bigger population will import more of any given commodity. But we're not talking about *any* two countries, we're talking about 2 very specific countries, which are equally well developed, and for which one has a population that is not only bigger, but utterly dwarfs the other. So yeah, other than some very specific items like some kinds of European food or something, I'd be surprised if there was even a single commodity that the UK imports more of than the US by sheer value. And if there is something, then that thing will be incredibly remarkable for the very fact that it'll be the only thing the UK imports more of.

    • MyLittleDashie 7 My numbers are based on science from the national Tea association. As I said in my comment per capita perhaps the British drink more. You need to read what I said. And just because a population is bigger, doesn't mean it's going to automatically import more. It's the same argument about GDP of a country.

    • Don't know where you're getting your numbers from, but they are bollocks. To be clear I don't care about gate-keeping tea from Americans, I don't even like it myself, but your numbers are way off, and by using magnitudes you're unfairly representing the consumption of tea in the two countries. If you're going to use sheer number then the US will probably beat the UK on imports of literally anything, that's what happens when you have a country with something like 6 times as many people in it. Per capita consumption is a much better metric to compare, and on that from the UK beats the US by a country mile. The UK has an annual tea consumption per capita of about 4.5 pounds, and the US is way down at 0.5 pounds. So about 9 times less tea is consumed per person in the US than in the UK. Also, people having tea in their house is meaningless. How long has it been there on average? How many people in the world buy a bunch of fruit only to have it rot, throw it out, and then buy more? Tea could be the exact same, something people just buy, but never actually use.

  • "Scope and field of application This International Standard specifies a method for the preparation of a liquor of tea for use in sensory tests, by means of infusing the leaf."

  • "I don't actually like tea." Tom is his own person and will not follow the masses for the sake of conformity. I'm a retired LEO in the U.S.A. and I can't stand coffee and I'm not particularly fond of doughnuts. My coworkers thought me peculiar. They were right, I'm proud to say!

  • I love it when one of your random videos is something I already know all about. This standard has been a running joke at my (design engineering) job for a while, there is a 'technical drawing' of a cup of tea, with "must conform to BS 6008" kicking about somewhere.

  • Some idiot got paid for writing that standard, and someone who probably didn't want to had to pay for it.

  • So you make it the Chinese way.

  • also one shouldn't use boiling water for green tea. :(

  • Forgive me if this has been said before but those with a military background will be familiar with the following - when asked how you would like your tea the 'standard' is NATO - if you say "NATO" you get tea with milk and two sugars - not really a standard but something that all understand.

  • For anyone wondering about differing boiling temperatures due to elevation, The boiling point drops by a little under 1 degree F for each 500 feet over sea level, so unless your trying to make a International Standard Cup of Tea - ISO 3103 on the top of mount everest, it's not going to make a lot of difference

  • the British take tea way too seriously holy shite

  • This is by far the most british video I have watched today.

  • So, how's life after losing your British citizenship, Tom?

  • OH THAT PLOT TWIST

  • 6min sounds right to me.however that could depend on the tea.

  • Great fun!

  • I audibly gasped at the end.

  • Hey, people in the US like tea too.

  • Now do a ISO episode of a standard US-tv video.

  • Triggerd

  • Not my cup of tea

  • The things you learn on the internet.

  • those glass pots, i see ur a fan of waitrose cheesecake, tom

  • what next? International Standard to Poop?

  • warming up tea in the microwave...

  • Where I'm from standard tea is sweet tea.

  • i have to admit its not often i have a cuppa, however i have found that Yorkshire Tea is by far the best :)

  • There needs to be an International Sandwich...

  • This process of making tea makes me more interested in making tea. Microwaving a mug with a teabag has always been a bit lack luster.

  • So the standard cup of tea taste standard. Shocking

  • What? A Brit who doesn't like tea?!

  • I now want some tea.

  • I would watch a Tom Scott cooking show ... probably because it would be breaking all the cooking show genre expectations and be a Tom Scott informational video instead, but still.

  • "I don't actually like tea" Once Tom said this MI6 came to his house for questioning on if he was actually British. They then proceeded to take away his birth certificate, passport and ability of queuing.

  • "I don't actually like tea" WHATTTTTT

  • Checked if this was made in April Fools. So either a) wtf Professional Tea Tasting Set xD or b) Tommy's internet lagged absolutely brilliantly and video had to be uploaded 8 days after April Fools

  • You don't like tea? *U N S U B S C R I B E D*

  • Were the 2 glass objects on the side empty GU dessert glasses ?

  • Sorry to say this: There was/is a TV-report of an tea house (a big importer in the port of Hamburg), where they tastes the tea the standard way. They flip the teapots very fast and don't get any spill on the table. The test was invented to get the right price for the chargo of a ship full of tea (if you bought it on food auctions).

  • What's so bad about microwaving old 3 day old tea?

  • Looks like a terrible tea though

  • when he said "specialty equipment that most people haven't even heard of" I thought he was going to be doing some kind of interferometry or mass spectrometry on it. instead it was weird special equipment that I hadn't heard of.

  • As an American, I have 4 British friends. I can honestly say I enjoy tea way more than 3 of them. The one who enjoys it as much as I do is a bit older, an ex RAF pilot and a radio engineer.

  • You tell very interestingly

  • "I don't actually like tea." Tom, I'm going all the way back to London just to take your British card.

  • No one likes tea. The brits are just so afraid of admitting it, because everyone reacts like the comment section here and wants to lynch them. It's flower-soup. Disgusting.

  • But will there someday ISO standard for a machine that can only make a liquid that is almost, but not entirely, unlike tea.

  • Half as Interesting did this too, cool!

  • That tea is wrong... OMG .. Jk, tea's gottah taste nice, so you make it to taste nice. If you don't like it, try something else. Shrug how you make it. Enjoy tea! It's great :)

  • This is the most british vidro ive seen

  • Same Tom. I don't like tea either. I prefer coffee

  • 6 minutes is way too much for many tea leaves. I'm accustomed to 30 second and one minute's usually the maximum.

  • Is it just me or does Tom Scott ALWAYS wear the same red tshirt

  • How to make the most mediocre cup of tea in the world.

  • the more you know

  • Your tea looks like piss in a cup after not drinking any water all day

  • Why would people think this would be the perfect cup of tea? It’s called ‘Standard’ for a reason 😂😂

  • This is something that I've wanted Tom to do a video on ever since I learned there was an ISO Standard for tea brewing.

  • 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...
