minimum dose size?

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Doing an experiment to prove someone on YouTube wrong. Yep, I had time today.

Normally I don't engage with the comments section, but someone said to always use distilled water in your espresso machine and I couldn't resist. Drawing on my (admittedly limited) knowledge of chemistry, distilled water has no ions and would strip the minerals out of the machine's metal components, causing them to degrade over time. (I didn't mention anything about taste since that's subjective and I didn't want to muddy the waters.) But he threw a curveball when he replied that nothing will leach out of stainless steel and that most coffee makers have stainless steel components.

Any chemists on here that can speak to that? Getting mixed results when I search the internet, so I designed my own home experiment with stainless steel spoons. One spoon is in distilled water (measured at 000 PPM) in a plastic bowl and one spoon is in the same type of bowl with filtered water (150 PPM). Identical spoons, identical bowls. If the distilled water degrades the spoon faster than the filtered water, then I'd expect the 000 PPM reading to increase at some point.

I'm also open to being proven wrong. Maybe taste is the only concern…
