This suggestion is simply about one thing:
Alcohol
A few days ago, I found an old 3-month old(in real time) glass of white wine in my old pouch in Harad. I wondered to myself, Why not make a suggestion about making wine age?
And so I'm here with this tiny suggestion. Note that this is purely for aesthetics and aging wont serve any purpose other than showing off or something more meaningless.
A wine barrel will have its amount of real-time hours existing right beneath where its potency level is.
thx for reading!
