Vertical grain is milled from lumber that has been cut perpendicular to a tree’s growth rings, also known
as quarter sawn or rift sawn. The face will have long vertical graining and varies from dead straight to
slightly wavy or curly and from very tight to more spaced out grain. Vertical grain will have fewer small
to medium knots, there are some nail holes and stains, and very minimal checking. The tighter and more
consistent vertical grain is a more dimensionally stable material and is highly sought after for flooring.
Vertical grain is not nearly as abundant as mixed grain and is priced a bit a higher.
