Common Names: Chestnut Oak, Rock Oak, Mountain Oak, Tanbark Oak Scientific Name: Quercus prinus (family Fagaceae) Tree Characteristics: Large deciduous tree reaching 60-80 feet with distinctive deeply-ridged, thick bark and chestnut-like leaves with rounded teeth. Produces large acorns and thrives on rocky, well-drained slopes.

Geographic Distribution

Where You’ll Find It: Eastern United States from Maine to northern Georgia, concentrated in Appalachian Mountains and piedmont regions Availability: Good availability in eastern regions from forest management, storm damage, and land clearing operations Growing Conditions: Prefers well-drained, rocky soils and slopes. Thrives in acidic conditions and challenging sites where other oaks struggle. Common on ridgetops and dry hillsides.

Burning Characteristics

Heat Output & Performance

• Sparking Tendency: Very low spark production provides excellent safety characteristics
• Flame Appearance: Steady, attractive flames with impressive heat radiating properties

Aroma

• Burning Scent: Clean oak fragrance with subtle complexity from tannin content
• Pleasant Factor: Pleasant traditional aroma widely appreciated by experienced wood burners
• Intensity: Moderate aromatic presence that’s distinctive without being overwhelming

Processing & Preparation

Splitting Characteristics

• Ease of Splitting: Moderate to difficult due to density and occasional twisted grain
• Grain Pattern: Generally straight but can be challenging due to density and tannin content
• Tools Needed: Heavy maul or hydraulic splitter recommended for consistent results
• Best Splitting Conditions: Split when green for best results – becomes more challenging when seasoned

Seasoning Requirements

• Drying Time: 15-20 months for optimal burning due to density and tannin content
• Moisture Content: Takes time to reach target 15-20% due to density and natural preservatives
• Seasoning Tips: Benefits from good splitting and excellent air circulation for even drying
• Storage Considerations: Tannin content provides natural preservation – excellent storage characteristics

Processing Notes

• Chainsaw Considerations: Dense, hard wood that can dull chains – maintain sharp equipment
• Bark Characteristics: Extremely thick, deeply-ridged bark that’s historically valued for tanning
• Handling: Heavy, dense wood with substantial weight requiring proper handling techniques
• Tannin Considerations: High tannin content may cause staining – wear appropriate clothing
