If you ever wondered where we derived our numbers from, then here is the data. This chart illustrates the Volume and Surface Areas of different size barrels. It then demonstrates the ratio of square inches to liters of volume. This ratio is then illustrated as a ratio to a 53 Gallon Barrel which is a standard barrel size for aging whiskey. Based on this ratio we derive the number of days weeks and months equal in smaller barrels to the standard whiskey barrel. We hope this information helps you better understand the process of aging spirits in relations to the different size barrels.
