A barrel cooler is a cooler that is made (or made to look like it is) from wine barrels. Some might even just be round metal or even plastic coolers. Just like a typical cooler, barrel coolers are used to keep drinks cold for any outdoor activities, such as backyard parties or barbecues. They are very stylish, often made from recycled wood, and available in a pine or butternut finish. Some even bear the name of the vineyard that used the barrel during wine production.
