Nuts
Quercus
A tier
Quercus labels the oak genus as a whole when trade or catalogs speak of acorns without pinning a single species. That breadth matters: tannin load, shell thickness, and starch balance swing hard from white oaks to red oaks to evergreen live oaks. Foragers and mills still crack, leach, dry, and grind under the same general craft, but leach water schedules must follow the actual trees in the bin. Generic Quercus lots can be excellent staple food if sorted and processed carefully, or disappointing if mixed species are leached on one short cycle. Buyers who need repeatable bakery colour should ask for species or regional type rather than accepting an anonymous oak mash. Quality checks stay the same—heavy nuts, no weevil dust, clean post-leach flavour. Treat genus-level stock as a starting identity, not a flavour guarantee.

History
Foraging peoples across oak ranges processed acorns into staple calorie foods after leaching tannins.
Korean and East Asian cuisines developed acorn jelly and starch products (dotorimuk traditions).
Indigenous acorn processing knowledge was documented while settler agriculture displaced oak mast staples in many regions.
Foraging revival and Korean-food interest returned acorn flour and jelly to specialty pantries.
