Fraxinus excelsior
European Ash
Pale, ring-porous hardwood with bold grain and the best steam-bending behaviour in Europe. Strong and tough, but strictly interior use.
Grown commercially in EuropeFamily: Oleaceae
Tree
Native across Europe from Ireland east to the Volga, north into southern Scandinavia and south into the Mediterranean uplands. Grows in mixed broadleaf forests on moist, fertile soils, often alongside oak and beech. KORENA sources from managed European forests where stand health allows responsible harvesting.
Wood appearance
A pale hardwood with a creamy-white sapwood that blends into a light brown heartwood. Grain is straight and the texture coarse and uneven, with strong contrast between earlywood and latewood pores. Growth rings read clearly across a flat-sawn face, giving ash a bold, graphic look that suits modern furniture as much as traditional joinery. A lighter, more open-grained alternative to European oak, and a far cleaner, paler option than walnut.
- Creamy white to pale straw sapwood
- Light brown to olive-tinged heartwood
- Bold dark latewood lines against pale earlywood
- Mellows to a warmer honey tone with UV exposure
- Bleaches well for very pale, Nordic-style surfaces
- Straight grain, coarse uneven texture.

Working with it
1 = difficult · 5 = excellent
Works well with both hand and machine tools. Glues, screws and finishes predictably. Pre-drilling is sensible near edges given the density. Ash is one of the great steam-bending species — chair frames, tool handles and sports goods have relied on it for centuries — and it holds curves reliably once set. Sharp tooling matters: the coarse texture can tear out around knots and interlocked patches if blades are dull.

Drying
Dries at a moderate rate with a moderate risk of checking and minor distortion. Tangential shrinkage is roughly 1.6 times radial, so quarter-sawn stock stays flatter in service. Acclimatise to the workshop for at least two weeks before machining, and condition again before final assembly in heated interiors.
Finishing
Takes oils, hardwax, water-based and solvent finishes well. The open ring-porous structure benefits from grain filler if you want a glass-smooth surface — otherwise the texture stays visible and tactile. Stains evenly, but the porous earlywood drinks pigment faster than the dense latewood, which can exaggerate ring contrast. Test on offcuts before committing. Bleaches cleanly for very pale Scandinavian looks.
Durability and safety
- Class 5 — Perishable
- Food contact safe
- Dust irritant: wear PPE
Ash dust is a documented respiratory and skin sensitiser. Repeated exposure can trigger asthma-like symptoms and dermatitis in sensitive individuals. Use a P2/P3 mask, dust extraction at the tool, and long sleeves when sanding or routing. The wood itself is food-contact safe once cured and finished appropriately.

Sourcing and sustainability
- Grown commercially in Europe
- IUCN: NT — Near Threatened
European Ash is reassessed as Near Threatened on the IUCN Red List because of ash dieback (Hymenoscyphus fraxineus), a fungal disease moving across Europe since the 1990s and killing a significant share of standing ash. Paradoxically this means salvage and sanitation harvests are common, and well-managed sourcing can use timber that would otherwise be lost. KORENA sources ash from forests with documented health assessments and chain-of-custody. EUDR due diligence is in preparation and becomes mandatory for large operators from 30 December 2026, and the slab passport is built to carry the legality and dieback context. No CITES listing.
Buyer questions
Is European Ash a good choice for furniture?
European Ash is best matched to projects such as Steam-bent chair frames and stools, Dining tables and desks for interior use, Cabinetry doors and drawer fronts, Tool handles, sports equipment and shop fittings, Wall panelling and architectural millwork, Turned components and lighter-toned table legs. The final choice should consider grain, finish, movement allowance, and the room where the piece will live.
How hard is European Ash?
The listed Janka value is 6,580 N and the density is 680 kg/m³. Use these as comparison signals, not as a guarantee of how a finished surface will wear.
What should I check before buying European Ash slabs online?
Check measured length, width stations, thickness, drying method, moisture notes, colour variation, defects, and origin. Compare the measured outline against the finished drawing before reserving the slab.
