I am not sure about coffee, but heating water in a microwave may result in superheated water, which is above the boiling point without boiling. This can be quite dangerous, as it might start boiling at any time. In chemistry you usually put a boiling chip in the water when heating it in a test glass to avoid this.
I'm pretty sure it also has to be contained in a pressure chamber too. If it's not, the steam just disperses into the atmosphere along with the excess heat.
It shouldn't happen with coffee, superheated water requires there to be nowhere for the bubbles to form but even tap water normally has enough minerals dissolved in it for that to not be a problem.
You wouldn't. You'd make new coffee. Not trying to be condescending. I literally wouldn't reheat coffee because if it's been standing long enough to get cold, it no longer tastes good.
I don't think what you said was condescending, it just sounds wasteful to me tbh. I'm not throwing it away just because it got cold and it doesn't taste fresh anymore.
Ah, so it's a sort of punishment for yourself for not drinking it while it was hot? You made it, so now by god you'll drink it? Maybe invest in an insulated cup or thermos then. 😂
It really takes some very special conditions for that to happen. Every time I've boiled water in the microwave it's always boiled fine just like on the stove.
No, don't act like it's because you're worried about their safety. It's clearly just another item Europeans use to condescend towards Americans. Both you and I know it.
I've not heard of this before but I also never boil my water in the microwave since it takes too long. Usually just warning it up (so 1 or 2 minutes depending on what I'm doing)
It is because you might create superheated water, which is not boiling while being above the boiling point. Since it can start boiling at any time, it can be a little dangerous to handle superheated water.
That’s what really happened in Flint, MI. There was no contaminated water, it was only an experiment in public safety to add supplements to the water to prevent the hideous catastrophe of explosive boiling. It will soon be rolled out nationwide
I remember this sweep over the internet. Considering the speed and simplicity of kettles for decades, what a weird thing to see of Americans. Especially since they made the first one ever.
Hey man, that's not true! I can go into the laundry room, unplug my dryer, and plug in a 220V kettle with a special adapter, or go out in the garage and unplug the table saw. Convenient options!
I have to believe it’s also the popularity. Maybe it’s too much my own experience but:
most people drink coffee
tea drinkers historically didn’t have a high end
Maybe I’m not sure how to phrase it but in my lifetime, coffee went from hideous burnt crap to something where we care about a high end. Coffee in general has gotten much better, there are way more choices, and there is a visible niche of people who spend way too much time and money looking for the perfect brew.
In the US, tea is following this path, but much later. Most of my life tea drinkers may have argue over the best brand of tea bags, but it was the same old swill their Moms may have used (they may disagree with that characterization). It’s only much more recently that tea in the US has become a “thing” something people pay attention to, something with a “high end”. At the grocery, tea choices are not as wide as coffee, but now you have a much greater variety of brands, sources, flavors, preparation methods. Tea is only in recent years enough of a “thing” to get excited over, pay too much time and attention to.
Or in my house, I don’t understand my teenagers and their weird tea drinking ways, when I have three different ways of making coffee. However this kettle thing is great for hot chocolate and caffe mocha
That demonstrates a fundamental ignorance of how electricity works.
Voltage is only half the power equation. The other half is current. Power = voltage x current
So if a kettle on 110V can draw twice the current, it will have exactly the same amount of power and will heat the water in exactly the same amount of time as a kettle on 220V that draws half the current.
