Tapping Pine Trees for Resin — Collecting Naval Stores from Longleaf Pine

A detailed guide to tapping longleaf pine (Pinus palustris) and other Southern pine species for oleoresin — the raw material that yields turpentine and rosin, historically known as naval stores. The US Southeast (Georgia, Florida, the Carolinas) was the world's largest producer of naval stores from the 18th through 20th centuries. Oleoresin is a natural mixture of volatile terpenes (turpentine, approximately 20%) and solid diterpene acids (rosin, approximately 80%). This blueprint covers the complete process: selecting mature trees, cutting the catface, installing collection gutters and cups, applying sulfuric acid stimulant to increase resin flow, collecting and straining the oleoresin over multiple rounds through the tapping season (March through November), and preparing for the next season.
