You can't just tap any tree anywhere. Maple syrup needs a very picky kind of spring weather — and Vermont has exactly it.
Maple sap only flows well when nights freeze and days thaw. That freeze–thaw pumping is what pushes sap through the tree — no freezing nights, no sap run.
Basis: Tree physiology of sap flow — taught in maple-country schools and by extension services.
Vermont's hills are covered with sugar maple forests, and its early spring swings between frosty nights and mild days — the exact recipe.
Basis: Vermont's sugar maple forests and spring climate are textbook geography.
Sap is almost all water. It takes roughly 40 buckets of sap boiled down to make 1 bucket of syrup — that's why sugarhouses puff so much steam in spring.
Basis: The ~40:1 sap-to-syrup ratio is standard maple-producer knowledge.
Native peoples of the Northeast were making maple sugar from sap long before European settlers arrived, and taught them how.
Basis: Established history of Indigenous maple sugaring in the Northeast.
