Grain Pattern
Mostly straight to mildly irregular, with broad cathedral figure and conspicuous knots; likely flat-sawn. End grain is not visible, so ring pores cannot be confirmed.
Color & Appearance
Golden honey-brown, with darker knots and variation between boards; oak typically deepens toward amber with age and light exposure.
Hardness (Janka)
1,120 lbf (European oak; Medium, near the Hard threshold).
Durability & Decay Resistance
Durable heartwood; good resistance to decay, with sapwood less resistant.
Value & Age
Approximately €5–€15 per board foot for typical solid European oak; flooring price varies by grade, finish, and installation.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot be reliably dated from this image; the floor appears finished and in use, but visible wear alone does not establish age.
Common Uses
Flooring, furniture, cabinetry, joinery, barrels, and construction.
Geographic Origin
Native to Europe and western Asia; widely grown and used in Portugal and across Europe.
Workability
Machines and finishes well, though knots and irregular grain can cause tearout; predrilling is useful near board edges.
Finish Recommendations
For flooring, use a compatible floor-grade oil, hardwax oil, or polyurethane; test first, especially on knots.
Notable Features
Distinctive bold grain and visible knots; oak contains tannins and takes stains and finishes readily.
