The tree
Juglans regia
Warm chocolate-brown hardwood with straight to wavy grain. Works cleanly, finishes beautifully, and reads as the maker's wood across European studios.
Juglans regia grows across central and southern Europe, France, Italy, the Balkans, and into Anatolia. EU yards source it from managed orchards and woodland thinnings, with French and Italian stock the most common at trade.
Grain runs mostly straight, with wavy or curly figure where branches and crotches meet. Texture is coarse and uneven, and at around 640 kg/m³ it feels solid in the hand without being heavy on the bench.
