It definitely will. After a couple years of experimentation and testing I've found anything over ~200F is basically undrinkable. It took me so long to figure this out because there were a lot of confounders -- I drank a lot of tea over the holidays back home, and while my parents' town is on the same water source I swear their florination is different, in a way that changes the mouth feel of the tea. I also had a new…

This reads like someone copypasted a post from some audiophile forum, then replaced words to make it tea-themed :) "The basically unlistenable hdmi cable has been only gold-plated once, and the direction of the signal is wrong". Haha, no offence, just made me smile

the german tea expert Ernst Janssen recommends to also use boiling water to prepare green tea as most of the teas are contaminated with germs and other things. different green tea brands including organic tea brands were tested by the renowned German test.de magazine and they confirmed that, also most of organic teas are contaminated. and since this is nothing you can easily check at home, better use boiling water. h…

Without buying the test, looks my tea vendor (Tee Gschwender) once again was at the top, so I think I’m good ;)

Varities of Chinese and Japanese green teas differ in their processing techniques so much that they require different preparation techniques as well. They possess distinctly different flavours, too. Most Japanese green teas are steamed past the harvest time – lightly (gyokuro), or more thoroughly (sencha), or anywhere in between depending on the grade – and some varieties can also be roasted (e.g. yabukita). Japanese…

Matcha started out on the mainland and came to Japan. As my Taiwanese dealer once said to an audience, she was grateful the Japanese still do matcha or she worried the technique and style would have been lost. Not to say they make it exactly the same, I wouldn’t know, but the origin is China.

I am a tea worm, I use to consume several kg of tea annually. I have often saw recommendation to not overheat tea over some degree of Celsius but when I try this I found the tea not ready. In fact I use to do opposite: I preheat the cup or teapot before throw some tea in it for making the tea even hotter.

When I’ve had loose leaf tea poured for me, the first steep went down the drain. That achieves much the same thing, also gets rid of the little bits that can get stuck in your teeth.

Japanese green teas are not usually steeped multiple times (though most will allow for a few steepings, and a few are designed for that).

This sounds a lot more like chinese teas, which are designed for multiple short steepings (gongfu ceremony) and more or less require a rinsing first steep.

Is it japanese green tea? Because that's what the article is about, if you're drinking black tea, or chinese teas, that is utterly irrelevant: they are different cultivars, selected and grown differently, with different harvesting and processing, and different brewing methods and temperatures.

You might well be Spiff and still have no useful input.

Yeah it seems so dried out you wouldn't have too much to worry about. As for boiling tea for sanitation, I took a wilderness first responder class and they taught us that you could bring water to a boil at any altitude a human can breath at (without holding it at a boil for 15 minutes as some claim) and it's considered sterilized. In Cusco, that would be around 191F/89C (humans can breathe quite a bit higher up than…

Many bacteria have mechanisms for surviving dry periods, ex: https://link.springer.com/article/10.1007/s00294-019-01036-z

We'd be drinking gamma ray sanitized tea if that had really been a problem. Honestly it sounds like mercury scare in seafood and pourover rice cooking for arsenic reduction, just not-invented-here behavior.

All foodstuffs are contaminated with germs, unless you go to extraordinary effort to prevent it (e.g. intense gamma radiation.) Unless there is some particular reason to care (you're a hospital feeding people who had their bone marrow nuked by cancer/chemo), then the correct solution is to stop caring. Who ever heard of people dropping dead because they brewed their tea with sub-boiling water? This isn't happening, i…

People mostly get by fine without boiling their salads but they do occasionally get e coli or something.

The germ thing seems to go back to this 2005 press release by the BfR, which does indeed urge people to use boiling water to kill Salmonella particularly when preparing herbal tea. It doesn't cite any known cases or numbers: https://mobil.bfr.bund.de/de/presse/presseinformationen/2005... Searching further, there were a couple of cases of Salmonella in infants in 2003 that were traced to fennel anise tea. The timing f…

You don’t need to boil salmonella to kill it: https://ourdailybrine.com/wp-content/uploads/our-daily-brine... You’ll have to work pretty hard to make a credible cup of tea with viable salmonella in it.

While I usually boil tea water, I just remembered I sometimes do cold brew tea (overnight with straight tap water). No gastrointestinal discomfort yet.

In some places, most of your instruments will likely be in Fahrenheit and Fahrenheit is what you use daily for most tasks. It only makes sense that you use Fahrenheit as your reference point. A home in other places is more likely to have Celcius, and you'll likely use it. It isn't like it is difficult to convert.

No, it is very hard to convert. The US has about 4% of the world population. Adapt. It's not worth the communication problems.

i suppose they will when they have to.
