Abstract
Disclosed is a method for accelerating extraction of compounds from oak to flavor wine. Barrel staves are cut to increase surface area so that the longitudinal dimension is exposed. The longitudinal dimension has a liquid penetration rate eight times faster than the radial and tangential dimensions. Cross cutting to increase longitudinal surface area enables winemakers to use less oak for flavoring than with current barrel alternatives
Claims1
A method for accelerating the extraction of soluble chemicals in oak for flavoring wine by:
- a) cutting oak across the grain,
- b) increasing the surface area of longitudinal faces rather than radial and tangential faces,
- c) increasing the permeability and penetrability of said oak,
- whereby wine in contact with said pieces will more quickly extract flavoring chemicals.
