Wood Species Guide
Sweet Birch
Betula lenta
Also called: Black Birch, Cherry Birch, Mahogany Birch, Spice Birch, Mountain Mahogany (regional)
What Sweet Birch looks like
Heartwood is a light to medium reddish brown, darker than most birch, and the sapwood is cream to pale yellow. With age it can pass for cherry at a glance.
Grain and texture
Straight grain with a fine, uniform texture and a moderate luster. Curly and wavy figure turns up now and then.
Working Sweet Birch: planing, cutting and gluing
Hard and heavy, but it machines cleanly with sharp tools and turns very well. Figured boards may tear out on the planer. Pre-drill for screws near ends, and it glues well.
Finishing Sweet Birch: oil, film finishes and epoxy
Finishes smoothly, though stain can blotch like other birches, so condition first or use a dye. Clear oil gives a warm cherry-like tone. The closed grain seals fast, so epoxy goes on with few bubbles.
Durability, stability and Florida humidity
Perishable outdoors and prone to insects. It moves a fair amount with humidity, so let it acclimate before final milling. In Florida, keep it indoors in air conditioning and finish all sides.
Shop notes from our Fort Myers shop
Sweet birch is the hardest and heaviest of the common birches, and lumber yards often mix it in with yellow birch. The reddish heartwood makes a budget cherry look-alike for cabinets and furniture. Scratch a twig and you'll smell wintergreen, which is how many folks tell it apart in the woods. We don't stock it, but ask us and we can often source it.
Common uses for Sweet Birch
Furniture, cabinets, flooring, millwork, plywood, turnings, tool handles and utensils.
