Yes - the high-tannin oaks like the Red Oak take a lot longer than the low-tannin ones like the White Oak. You can tell by biting into one if it needs more soaking. Tannin won't kill you but it tastes pretty nasty. OTOH, it will cure leather...
Much appreciated, again.
You can eat acorns if you have to, but if you have enough game meat, berries, tubers and fruit, it is probably best to leave dubious foods alone, and by this I mean foods that have to be soaked, sprayed, danced around or prayed over to become edible. I don't eat anything that has to go through a filtration process, except whiskey.
The fresh water streams and rivers in this area (Mobile) are the color of tea from all the oaks in this area. The soil is very acidic too.
...sooo...to be correct...it's White Oak with fish and Red Oak with meat?
