How do you heat liquid water to more than 100°C? Coffee is supposed to be just below 100°C when you brew it, or it is not good. Goes for home made or McD coffee. Whatever, maybe in some parts of the world, the laws of physics don't apply and liquid water does not lose energy though evaporation... Back on topic: Dropbox is telling everybody that they are "encrypting" stuff on their drives. How do they decrypt without a password? This case is a much different from the "stupid McD coffee customer" case, because details on cloud storage technicalities are not common knowledge, whereas "boiling water may be hot" kinda is.

> "boiling water may be hot" Most people don't equate 'boiling water' with 'coffee.' Sure you need to boil water to brew it, but I've never been handed a bubbling cup of coffee.

    "hot liquid" and "liquid so hot that it will burn my skin" are not necessarily the same thing. Unless you think that people should feel afraid of a hot bath or a hottub (or even going to a hot spring). In more precise terms, 'boiling' is a subset of 'hot.'

      Wow, you all are really discussing this? If "hot" may mean "hot" or just "hot" and if the fact that hot coffee is hot is common knowledge? Thanks, now I understand why it is so important to write obvious things on products in the USA. Maybe it actually is necessary...

If you increase the atmospheric pressure, you can raise the boiling point of water well beyond 100°C. Of course, that has little to do with brewing coffee. So you bring the water to a boil, and then let it sit for a minute, then pour it over the grounds. Then as the coffee steeps, the liquid further cools down. It is just below 100 when you brew it.... not when you drink it. It is much cooler when you drink it, (65 to 80 C).

  When you buy it, it is usually around 90°C. Same when you take it from a coffee maker. Ever noticed the small heating plate below the coffee can? Who cares. Just be careful with hot stuff. And if you fail to do so, sue somebody to avoid blaming yourself. I guess.
