Can water prevent ground coffee from going stale?

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...

Can water prevent ground coffee from going stale?

So I had this thought in another thread and I was wondering if anyone else had an opinion: Could you store ground coffee in a slurry to prevent it from going stale/oxidising?

Imagine you grind 20 grams of coffee to brew 48 hours later. Usually it would lose quite a bit of flavour by the time you brewed it. But what if you added just enough water (let's say another 20 grams) to fully saturate and cover it, like a 1:1 cold brew. And suppose you then brewed with that slurry instead of the stale powdered coffee, adjusting your brew ration and temperature accordingly. Would that produce a better result?

I want to say that it could work, though I've never tried it. I know heating cold brew doesn't produce fresh coffee flavours, but I've never tried heating it up with the ground coffee still mixed in. Thoughts?
