As a general rule I would say to just heat the water up only in the microwave and then steep the tea afterwards, then add milk and sugar to taste when you're done. You can experiment with what works best for you. Microwaving to heat water generally is suitable only for black teas, since you don't have any real control of the water temperature. The only thing you should keep in mind when microwaving is that water can get hot without appearing to boil:

https://www.youtube.com/watch?v=1_OXM4mr_i0

:eng101: This is because it doesn't evenly heat the water.

quote:

A kettle is designed to heat water evenly to 212 degrees Fahrenheit (100c). Heat at the bottom of the kettle—whether from a heating element embedded in an electric device or from a burner on the stove—creates a natural convection current: The hot water rises and the cool water falls in a cyclical fashion, which uniformly heats the contents of the kettle to a boil (at which point an electric kettle clicks off or a stovetop kettle whistles).

But microwaves don’t heat water evenly, so the boiling process is difficult to control. Microwave ovens shoot tiny waves into the liquid at random locations, causing the water molecules at those points to vibrate rapidly. If the water isn’t heated for long enough, the result is isolated pockets of very hot or boiling water amid a larger body of water that’s cooler. Such water may misleadingly exhibit signs of boiling despite not being a uniform 212 degrees (100c). For instance, what appears to be steam rising from a mug of microwaved water is only moist vapor evaporating off the water’s surface and condensing into mist on contact with cooler air—it’s the same principle that makes our breath visible on frigid days.

Why is water temperature so important to good-tasting tea? When tea leaves meet hot water, hundreds of different compounds that contribute flavor and aroma dissolve and become suspended in the water. Black tea contains two kinds of complex phenolic molecules, also known as tannins: orange-colored theaflavins and red-brown thearubigins. These are responsible for the color and the astringent, brisk taste of brewed black tea, and they are extracted only at near-boiling temperatures.

Water also cooks certain volatile compounds, chemically altering them to produce more nuanced flavors and aromas, such as the earthy, malty, and tobacco notes in black tea. When the water isn’t hot enough to instigate these reactions and produce these bold flavors, tea tastes insipid.

Overheated water results in bad tea, too—and this is also easier to do in a microwave than in a kettle, since there’s no mechanism to indicate when the water has reached a boil. The longer water boils, the more dissolved oxygen it loses—and tea experts say that dissolved oxygen is crucial for a bright and refreshing brew. Microwaved water can also be taken to several degrees above boiling if heated for too long (which is impossible in a kettle, because the metallic surface prevents overheating). Such ultra-hot water destroys desired aromatic compounds and elicits an excess of astringent, bitter notes by overcooking the leaves. Overheated water can also accentuate naturally occurring impurities in the water that contribute off flavors to the final brew.

Yeah, that. This person's got the data.

In other news, I got a Bonavita variable temperature gooseneck kettle in via Massdrop today. Very excited to use it for fancy tea prep, but I don't have any thermometers or anything like that to actually check to see if the numbers I'm dialing in are accurate at all or not. If not...I guess I can use it for pourover coffee or something? I haven't really had to get too.

I guess it's supposed to be accurate within 1%, which seems quite specific! I guess it's intended for commercial use, but considering I got it for 58 bucks shipped on a group buy instead of 100 bucks or whatever it retails for.

Teavivre green and white sale yesterday i bought over $100 of tea. I saw it and was like $9 for 100g? Well hell a cup of bag tea at a coffee shop is $7, I'd be a full not to get this... And this... And this... And :eek: that's a big total. By the end of this sale I'll probably have spent between 200 and 300 on tea.

And i already have a huge back log of my stuff from Vietnam, Macau, Taiwan, and Hong Kong.

I don't really get their grading system tbh, I've never seen those terms used anywhere else. Just assume it's a higher grade than their normal stuff, and that if it's organic that you're paying a little extra.

If you want to get fancy with it stopping in a Chinese tea shop and buying a scoop (usually sold as a single item, or as part of a multi-piece gongfu tools set like this one here - they roughly measure out to a teaspoon and a half, and the angled scoop is useful for if you're trying to measure out from a bag of looseleaf.

Of course, I've also used it with a scale and it provides great control for when you're trying not to add too much leaf to your stuff!

Hey tea thread - looking for a shove in the right direction. I got a cold brew coffee toddy as a gift, but have decided I don't really like the caffeine buzz I get from coffee. I do however, really love tea but pretty much have just had bagged/basic stuff. I'm having trouble finding any methods to use the toddy for making cold brew tea, even though the box references it - their site has pretty much nothing. I'd love to be able to keep a jar of this in my fridge for a few days or weeks but have NO idea where to start.

I have some local tea shops (teavana of course, and some other small ones) or can buy online, but really have no idea where to start with tea weight vs amount of water, what types would be good, etc. I'm pretty much down to try any tea but wouldn't mind starting out in the less expensive or basic ones!

This is what I always link for cold brew. http://verdanttea.com/how-to-make-iced-tea/ I use the same ratio, 4g to 12 oz (a little less for puerh). You don't really need any special devices, any kind of mason jar or pitcher with a cover or you can just use saran wrap.

If you have a thermos with a screw on lid, you can shake it up in there to similar effect. If you have a french press (doesn't sound like you do) you can also put it in there with hot water and ram the filter up and down to make it frothy. Matcha's great for having a quick cup of iced green tea, too. You can just stir it right into some ice water and there ya go.

I ended up just stirring some into some cold water, and then pouring my boiling water on top of it to achieve something close to the 74c recommended on the package.

I'm a bit underwhelmed. Maybe I didn't put enough in, or something. Is the whisking and frothing really important to the experience? If so maybe I'll go all blender on it later.

Ooooh I should start putting it into my protein shakes...

Added flavors are pretty normal. It's one of the reasons I don't like them at all. To me it makes the tea taste a bit like chemical. Some people really like it though. So try things and see if you like them!


And DontAskKant - I have at least 3kg right now myself. It's perfectly natural to keep buying more tea than a human being can logically drink.

Lavender is a very strong scent/flavor and can easily be overpowering. If you've never tasted it before, you might want to try buying plain dried lavender and adding a tiny amount to an unflavored tea for starters. I have a 1 oz. bag that's lasted forever because a little bit goes a long way. That said, I think it's pretty good with black teas like breakfast blends and greys, but everything I've tried that already had lavender in it had way too much for my tastes.

Looks like a green tieguanyin. A western style brew would be 180-190F water, 1.5-2 minutes, 4-6 grams (or 2 heaping teaspoons) for about 2 cups/16 oz. You can resteep a couple of times, increase the steep time by 30 seconds to a minute per additional steep.

Got myself a teapot and infuser recently, been using an old Keurig as an electric kettle (it only heats water to below boiling, but that seems to work okay for me.) There's a cafe near here that sells the loose leaf teas they brew. I have no idea if the "Ceylon" I got from them is actually Sri Lankan as I don't know their supplier and I didn't see the lion stamp on anything, but I got a generous amount of it for 5bux so that's what I've been drinking.

That's an Anxi oolong of some sort, TiKuanYin is the most likely but there are all kinds of smaller varieties. If brought back from China there is a chance it has a flavor in it like jasmine or osmanthus, as those are much more popular domestically then they are for export.

Get a little teapot and dump it in loose, about 1 teaspoon per person you are serving. Boil some water and let it cool to about 90c or so. Fill the pot till the leaves are just covered, swirl gently then wait a few seconds then dump that water out (or drink it, it will taste bad though). Then fill the pot with water and wait .5 to 1.5 minutes or so. Every oolong is a bit different on times and temperature. Many prefer to err on the side of weakness for the first steep. You can get 4-5 good steeps out of a quality Anxi oolong. After the 2nd steep you can up the temp and the steep times, its pretty hard to hurt these later pots. You will need a strainer of some sort for pouring to catch the leaves, which will expand considerably. If serving more then two, it is normal to pour into a serving cup or pitcher first, then into the drinking vessels to mix the weaker tea from the top of the pot with the stronger tea at the bottom.

https://www.youtube.com/watch?v=G1hjky2glaA

This lady is preparing the same sort of tea in a ceremonial way, in a gaiwan though, not a teapot. She uses the first wash of water to heat the serving cups, which is traditional. She also does the weak first steep, also traditional. Neither of these practices are common for everyday drinking. Most folks who drink oolong alone, myself included, just drink it out of the gaiwan.

Thanks for the advice, vaseline and taters.

I ended up steeping it like a green tea, but a bit longer, which turned out to be a good choice. I steeped it 5 times, at the fifth time it started to turn stale, so I left it at that. Tasted fantastic, and I'm really glad he insisted on me taking that bag.
Later I made another cup in what has been described to me as "Grandpa style" (putting less tea than usual into a rather big mug and refilling with hot water as you drink, and just leaving the leaves in) because :effort:, which tasted fantastic as well, even if it probably wastes some of the potential taste.

No, I thought this was due to not having nucleation sites in the water to allow boiling? If you get a good beaker, that's very 'smooth' in the inside, lacking the sites, you can superheat.
The nonsense you quoted makes no sense to me whatsoever. It could, though, if you had a large amount of particulate matter in superheated water, then stir, causing instant boiling where only simmering or less was occurring. Is that the same principle you had quoted?
