Tärimittytte

Tärimittytte is a Finnish term that translates literally to "tar measurement" or "tar count." It refers to a method used in historical forest management, particularly in the logging industry, to assess the quality and yield of pine trees for tar production. Tar was a valuable commodity in maritime and industrial applications for centuries, used for waterproofing ships, preserving wood, and as a fuel.

The process involved examining standing pine trees, often older ones with thick bark, for signs of good tar content. Foresters would look for specific characteristics such as the presence of a healthy, resinous heartwood, which was essential for producing high-quality tar. They might also assess the tree's age and growth pattern, as these factors could indicate the potential for a substantial tar yield. Sometimes, a small sample might be taken or a visual estimation of the potential tar volume was made.

Tärimittytte was a practical, albeit somewhat subjective, way to select trees that would be harvested for tar distillation. It informed decisions about which trees were most economically viable for this specific purpose. While not a precise scientific measurement by modern standards, it played a role in sustainable forest use by focusing harvesting efforts on trees best suited for tar production, and indirectly, on the overall health and management of pine forests. The practice declined with the advent of synthetic alternatives and changes in industrial needs.
