Shannon's Lumber Industry Update · 160 – Peruvian Walnut

Peruvian Walnut Is difficult to dry

In this episode I feature Peruvian Walnut and talk about how it has become a flooring species. Specifically how its drying difficulty drove it to be a flooring product. Additionally I talk about juvenile wood, Jindai wood, and the Hickory/Pecan confusion.

Featured Species: Peruvian Walnut

Juglans neotropica or Peruvian Walnut is a Walnut cousin that contains several species native to central and south America.  Its a darker, richer color than Black Walnut with less sapwood.  Though due to the way it clings to moisture during drying it can often have white streaks throughout the heartwood.

Its is used for furniture but has become a strong flooring species due to the rich color but how it needs to be dried in thinner, narrow boards.
