ABSTRACT:
A process for obtaining a blending and ageing additive from oak wood which comprises (a) mixing oak wood in subdivided or particulate form with water, alcohol or mixture thereof; (b) enzymatically digesting the mixture at elevated temperature; (c) adding wine or other alcohol to the digestion mixture after the digestion is completed; (d) refluxing the resulting mixture at elevated temperature until the wood changes color and the liquid phase no longer changes color; (e) separating the resulting liquid phase from the wood; and (f) distilling the liquid phase to obtain a clear or water-white distillate and solid extract. The distillate and/or extract may be added to wine or other beverage, or other composition such as vinegar, to improve properties thereof.
