The tree
Quercus robur
The default European hardwood for furniture, joinery and architectural slabs. Open grain, calm colour, predictable behaviour at the bench.
Quercus robur grows across Europe, from Iberia to the Urals, and most slab-grade stock comes from managed FSC or PEFC forests in France, Germany, Poland and the Balkans. Supply is broad and EUDR documentation is well-established.
Pale tan to mid-brown heartwood, often with an olive cast, sitting against narrow cream sapwood. Grain is straight and the texture is coarse, with large open pores in the earlywood. Quartersawn faces show pronounced ray fleck, silvery, ribbon-like figure that is a signature of the species and of Mission and Arts and Crafts work.
