Birch
Handloggers’
Opinion
Birch is quite similar in appearance to maple’s tight, hard,
even grain. We sell a beautiful red birch that is a pale pink
to red-brown in color that can have white sap included. We also
sell a cream colored yellow birch. Customers like birch because
it is livelier in appearance than maple but does not have the
strong grain of the oaks.
Appearance
Color: In yellow birch (B. alleghaniensis),
sapwood is creamy yellow or pale white; heartwood is light reddish
brown tinged with red. In sweet birch (B. lenta), sapwood is light
colored and heartwood is dark brown tinged with red.
Grain: Medium figuring, straight,
closed grain, even texture. Occasional curly grain or wavy figure
in some boards.
Variations within species and grades:
Yellow birch, sweet birch, paper birch. Paper birch (B. papyrifera)
is softer and lower in weight and strength than yellow or sweet
birch. However, yellow birch is most commonly used for flooring.
Boards can vary greatly in grain and color.

with excellent shock resistance.
Workability
