From a company that has been known for producing eco-friendly products comes another idea that minimizes waste. These barrels give barrels used for fermenting red wine at California Vineyards a second life. The wine barrels are only useable one time for wine fermentation and then are usually thrown into the landfills. The barrels, made of African oak, are extremely durable and structurally stable, although they do weigh considerably more than plastic barrels of the same capacity. Since these barrels were originally designed to hold and seal liquid in them, they are ideal for capturing and storing rainwater.
