Will dried ginger piece be more potent than dried ground ginger of same age and storage?
If you get 2 sets of black peppercorns, leave one set whole and ground the other then leave them both out over time the ground version will loose potency and aroma due to being exposed to air. When one uses/grinds the whole set at the point of use the potency will be far superior.
I want to know if dried ginger unground and dried ginger ground and left out for the same amount of time will have the same level of superiority? In another answer I believe I read that dehydrated ginger(even if not ground) will loose potency over time but this doesn’t really happen to whole black peppercorns.
If then the dehydrated unground ginger does loose potency over time will it still be significantly superior to ground ginger or will it be quite bland/just a little superior so there’s no point not grounding it earlier if you are doing so to try and preserve potency.
Thanks.

Ground spices will turn bad (go stale, loose potency) faster than their unground (whole) state.
This is because ground spices have a lot more surface to air ratio and will oxidize quicker; oxygen is the culprit.
This is the case for ginger as well as any other spices.
This is why most people will keep spices whole and grind/crush them at the last minute.
If you want to keep ground spices for a long time, you need to keep them in an air free environment, vacuum seal pack will help, but each it you want to use some, you will need to open the package and vacuum seal it again.
