you must like ' Counter Aged ' coffee.
Ive noticed my Coffee Ground Stash
near composting time , has been partially colonized
w green fuzz no ordor at all
but the grounds might have a tiny bit of sugar in them
as I use the same filter to pass the sediment ( tiny bit of sugar / each cup )
left in my cup and add that to the Mass
I didn't know that , re H2O2
I do know what happens when you add K-Permanganate to it
dont try this at home
