Well done comment mate.

F the BBC, make it a netflix Show!

@@BB-hc9jj even better.

@@bradyoung8415 Exactly! I could listen to Don Mei all day! Have done, in fact!

I was a bit anxious for him.

;) we like obsessive people so cheers for watching

Don't start watching Tea house ghost or you'll have two channels to obsess on

Haha it is a pandemic tea virus xd

They’re such a good resource and nice to watch

Hi,please Confess Jesus As Lord with your mouth And Believe He Died For our sins And God Rose Him From The Dead,turn away from swearing, using God's Name in vain, making someone else sin, decieving, Praying to statues,Mary,Saints,Angels...,lying,over eating,magic,selfish ambitions, laziness, working On Saturdays(starting friday night by our time)pride,lust,hate,gossip,cigars,drugs,video games,movies,anime,idolatry(obssesions,un healthy connections to something,someone,addictions..) and that kind of stuff,Dedicate yourself To God Fully,Obey Him And Trust In Him And Jesus.

Well said. The island tour made this really fun to watch.

If only we could be on an island every week!

This was a great breakdown with interesting visuals. Thanks.

Thank you!

@@MeiLeaf also i was amazed by how you filtered out the sound of wind during the motorbike scene

How can he pull off presenting all that information while driving a motorbike?

Naturally occuring caffeine and the caffeine used in energy drink are chemically identical

@@Lisa-jo1cd right but 25g is different from 150g

Hey Alex, This does not make any sense. Given the same variables (amount of tea, water, temperature) a longer brew will extract more caffeine. I have not seen any study comparing the amount of caffeine from a 5 min brew vs 20x 15 second brews. Maybe this is their meaning? BTW I am up for that collab if you want to explore then please email!

Ok. That's what I think anyway, and that's also what I can feel when I drink chitir' leftovers haha. ( 100% up to do something )

I sent a KZfaq private message :)

Mei Leaf I would love to have it too please! Amazing video, really instructive thank you!

I think it related to the fact of the tannins binding caffeine. If you brew longer you get more tannins taking off the caffeine effect, but you also get more caffeine on the other side.

OK!

Fain I would really like to see that too! I live in Texas, and we have abundant hard water! Curious to know if I should be doing tap water or bottled. Or what effects the hard water could have on my teaware.

Yes this one is incoming too!

Fain Agreed!

I believe it also has theanine. I've been drinking tea gong fu style daily for years. Once I decided to try Yerba Mate. I drank it in a gourd with a bombilla all day long. I did this for about a month. Initially I loved the taste and the way it made me feel. It gave me way more energy than tea and honestly I felt great.(at the time) But then I realized that the month had gone by in an instant. No joke. It's as if it literally sped up my life. So I went back to tea and life slowed down again. I am not a fan of Mate and I view it as an addictive drug almost. I felt great at the time but it really messed me up. Just my personal opinion and experience. It's probably worth noting I have extreme anxiety, some PTSD and depression when the PTSD kicks in. I take no pharmaceutical drugs. Tea is the only medicine that I use. It calms me down when I need it and keeps me mentally strong. So I probably shouldnt have tried Mate to begin with.( if it ain't broke. Dont fix it.) Sorry for the long comment. I just wanted to share my experiences. Have a nice day.

Guayusa is an interesting alternative as well. Similar to mate, it has caffeine and is said to have theanine as well (I don't know if this has been confirmed). For me it has a much milder effect than mate. Doesn't taste as good as tea though!

GoneKiffen that's very interesting. I wonder if it's just the caffeine levels that weren't working for you, or if there's something else in mate that was responsible. The theanine content is pretty cool, and mate also has some theobromine (of chocolate fame). Not sure if guyasa does (seems to be much less researched), but that one is also a solid functional drink.

Well, how did it taste?

@@jdubdoubleu Their tea is truly amazing... I've looked for some that I could order here in the U.S. since then and I always end up back at meileaf... I am currently drinking some of their guangxi silver needle... I'm not going to try and describe flavors because I don't have as developed palette as most and I wouldn't want to mislead you, but their tea is very delicious and to me it is worth the premium price... if you're on the fence order one of their flight boxes... they're reasonably priced and you get an assortment of tea. It's a great entry point to decide what best suits your taste too!

Yep this one was yours!

Wow! It was so much more informative than I thought! Thank you so much!

A lot of information thrown at you but you asked for it so there you go!

Great I am glad it was helpful! Let us know when the book is coming.

@@MeiLeaf Yes, sir-I'll be more than happy to send you a copy and see what you think :-)

You don't know that for sure, you can't just blame caffeine for muscle pain based on a little dabbling research. Stomach pain, yes.

Me too i just got diagnosed with Barrett's esophagus, i HAVE to rid myself of caffeine, my life depends on it.

matsdonder I agree! I never knew how much I move my hands until I started this channel! Thanks for subscribing.

Cheers George

Go Azman!

Cheers for watching

Yes this is the approximate amount of caffeine in 250ml cup but I guess that it is a similar amount in a 100ml Gong Fu brewed cup.

pooja bhandari hi pooja. It does not make the tea unhealthy but the casein inhibits some of the flavanols which have a antiox effect on the body.

We enjoy the reportage filming too.

All coming in a few months - we are heading to Japan to film everything.

Mei Leaf I can't wait! I love Gyokuro and matcha!

@@TopNotchReptiles I drink matcha ceremonial grade and organic, for the past 20years,daily. Love it but concern about caffeine

I'm sufering from anxiety and panic disorder. so I surely can not drink coffee. and even black/green/ oolong tea can get me anxiety and panic attack. so I can only drink herbs tea and flowers tea. but apparently I have to be careful with rose bud tea. tried 3 small buds and steeped for 5 minutes in a cup of boiled water, and it went fine for me. but today I found out, 4 big buds + 1 cup boiled water, steeped 15 mins (+ 1 tsp honey later when it cooled down), and it got me anxiety and panic attack pretty bad. heart palpitation, disoriented, jittery, stomachache, and finally the most horrific is impending doom (as always). and I thank you I found your vid. this gave me quite clear explanation about caffeine. for I have read an article wrote rose buds still contain caffeine -but I didn't believe it-, now I do. 😌

This one is being made soonish!

As for the alleged higher caffeine content with longer withering, you can't induce the production of any further caffeine once the tea leaves have been plucked and "killed" (conversely, you could theoretically denature or remove some of its caffeine content). Alternatively, you could increase the bioavailability of its caffeine content, so it would be more readily released into water when brewing the tea. But that's not what they usually measure in the lab when they compare different teas, but rather the maximum caffeine content they can extract by leaving the tea a much longer time in water. E.g., boiling water was poured on tea leaves and stirred for 10 minutes: agriculturejournals. cz/publicFiles/08057.pdf You could concentrate the caffeine content by partially degrading or removing some of the other components present in the tea leaves, such as water, which is one of the purposes of the withering process. But if at the end point of the process all tea varieties have the same water content, the greater water loss during a longer withering phase would be irrelevant. There are other components present in the tea leaves that are degraded during the withering phase. Apparently, chlorophyll begins to degrade, some of the carbohydrates are broken down for use as energy, and the polyphenol oxidase and peroxidase enzymes becomes active, as a result of those degradation processes, some of the volatile compounds dissipate (including CO2). A greater extent of degradation would render a higher caffeine concentration in the remaining dry matter (assuming the extent of caffeine degraded by such processes is negligible).

+Mei Leaf, you failed to mention why caffeine is toxic to insect pests. Does caffeine also block the insects' adenosine receptors inducing in them jitters or anxiety?

Cheers Jake

I'm glad I'm not the only one that noticed that

Depends on how you scoop them by weight or by volume. If by weight, the darker roast would have more caffeine, if by volume the lighter roast would have more caffeine.
