Using this product will make your wine, beer or spirits taste as if it has aged for years. Each packet contains two pouches - one is glycerin and the other is liquid oak. Together these two ingredients will smooth out the harshness of any young wine. Glycerin is commonly used in liqueurs but can be added to wine, beer or spirits. It provides a heavier mouth-feel. The liquid oak will quickly impart oak flavors without having to use messy oak chips or expensive oak barrels. One packet is sufficient to use on 5 or 6 gallons of wine.
