Picea sitchensis • Softwood
Grain Pattern
Exceptionally straight and tight vertical grain; uniform with very fine texture; quarter-sawn appearance showing high ring density
Color Description
Heartwood is a light creamy white to light pinkish yellow; sapwood is not clearly demarcated but usually a paler white; develops a golden-yellow hue with age and UV exposure
Hardness Rating
510 lbf; Classified as Soft
Durability Rating
Slightly Durable to non-durable regarding decay resistance; low resistance to rot and insects
Common Uses
Acoustic guitar soundboards, piano soundboards, aircraft components, boat building (masts/spars), and construction grade lumber
Geographic Origin
Coastal Pacific Northwest region of North America (Northern California to Alaska)
Market Value & Sustainability
Estimated Market Value
$15.00 to $45.00 per board foot for Master Grade instrument quality; lower for construction grade
Wood Age Estimate
Freshly milled to recently dried; lacks deep golden patina characteristic of aged or antique spruce
Sustainability Status
Least Concern (IUCN), though old-growth stands are increasingly protected; FSC certification is widely available
Workability
Excellent for hand and machine tools; saws cleanly and glues easily, though sharp blades are necessary to avoid fuzzy surfaces due to low density
Notable Features
Highest strength-to-weight ratio of any wood species in the world; outstanding acoustic resonating properties; light resinous scent
Finish Recommendations
Responds best to thin finishes like nitrocellulose lacquer, shellac (French polish), or light oils to preserve acoustic resonance
Identification Confidence
High; the extremely uniform, tight vertical grain and creamy color are classic indicators of high-grade Sitka Spruce used for musical instruments
