WineFrog explains Liquid Oak
Liquid oak is an oak substitute which is often utilized to add oak characteristics to wines of lesser quality. A desired amount of liquid tannin can be added to a finished wine. It works by binding with the alcohol of the wine. In order to create a more well-rounded oak influence on the wine, liquid oak is often used in combination with a dose of oak powder.
