Barrel making, also known as cooperage, is the craft of creating barrels from wood. This process involves selecting high-quality timber, typically from trees like oak, which is known for its durability and flavor-enhancing properties. The wood is then cut into staves, which are shaped and assembled into a barrel using metal hoops to hold the structure together. Once assembled, the barrel is often charred or toasted on the inside to enhance the flavor of the liquids stored within, such as wine or whiskey. The final step involves sealing the barrel to ensure it is watertight, allowing it to age and develop unique characteristics over time.
