huh. I use an expensive coffee maker precisely because it heats just shy of boiling, 202 degrees/like 94c, and it turns out way better coffee than the 85 ish degree machines.
For coffee machines the temperature doesn't matter as much, but for pour over, and some other filter coffee methods it can be important to measure water temperature.
It absolutely matters, it's why I paid so much. Walmart was selling a 50 dollar machine did the same thing, but the machines broke inside of 2 weeks. It made such good coffee I just returned it over and over till the customer service lady told me (she knew my name at this point) they'd returned what was left of the pallet. 300 dollar Zojirusha does the same thing and its a few years old now. Tried a few machines in between, just made mud it felt like, I've been ruined for crappy coffee tolerance.
Fair enough, there actually are a lot of terrible coffee machines available, especially in the US I guess. I am much more limited in what I can get, and so I end up having to do a lot more research (I do mean months of research), especially as the culture here is different for purchasing and returning things.
