The better Wenge, in terms of quality, is typically the one that exhibits fewer knots, a more consistent color, and a smoother texture. This is because these characteristics indicate a higher grade of wood, which is less prone to cracking and warping over time. According to the American Hardwood Export Council (AHEC), higher-grade Wenge has a Janka hardness rating of around 2,800 lbf (pounds-force), which is significantly harder than lower-grade Wenge, which may have a rating as low as 1,800 lbf. This hardness makes higher-grade Wenge more durable and suitable for high-end furniture and flooring applications. Additionally, the AHEC reports that the best Wenge comes from trees that are at least 50 years old, as these trees have a denser wood with fewer defects.
