Why spend money for expensive oak barrels when there is an effective, inexpensive alternative? Dickson's premium wine bags hold oak or other flavoring wood chips which can be dipped into the vats. The porous construction of the netting allows maximum flavoring to permeate the wine while preventing contamination by holding the chips firmly in place. Available in many sizes and textures to fit your specific needs. USDA approved - imparts no flavor of its own.
