My last couple of electric kettles had various levels for coffee, black tea, herbal tea and then the roaring boil of the 212 of your freedom units. I suspect the roaring is due to all of the freedom.

I'm surprised the coffee setting is so low compared to the teas.

I've never really paid attention to how longto leave a tea bag in. Usually it's stayed in the whole time while drinking it. Recently I've started to read the boxes the tea comes in and Earl Grey is like 3 minutes depending on the brand and herbal is 5-10.

As for number 5 I've read back when China was becoming more common place it was almost a caste level nod if you put your milk in first or last.

Early cheaper China would crack or break from hot water/tea being poured directly into the cup first. Placing the milk in first helped cover up this flaw by cooling down the tea.

Pouring your hot tea directly into your cups without the milk first was a subtle flex of your superior China quality. I do miss some of this nuance in a world that's seems to be on full blast most of the time.
