After completion of the hull, the staves are then bent to give the shape of the barrel.
There are different methods of bending. We apply a bending by traditional heating at Tonnellerie Bernard. This is a sensitive stage because it is necessary to control the exact degree of heating to avoid rupture of the staves.
The barrel is placed above a brazier fed with oak scraps. The heat slowly softens the wood fiber while the barrel is continually wetted internally and externally to maintain good hydration. Gradually, the capstan cable placed around the barrel is tightened in order to bring the bases of the staves closer together. The barrel gradually takes its rounded shape.
While the wood is warm and flexible, we then place the mold circles by adjusting the joints. All the staves need to follow a perfect alignment.
