ELI5: my Keurig coffee maker has a "strong" setting, what makes the coffee stronger if it's the same amount of coffee with the same amount of water?

It allows the coffee to extract longer by increasing the time that the coffee is in the hot water physically.

By increasing the time that the coffee grounds sit in hot water, the stronger the water is flavoured with coffee.

A longer soak is a thicker bev.

The same principle works for socks and old ladies.
