Squarrels use 1/3 the wood of a traditional barrel
WHICH IS THE EXACT AMOUNT OF WOOD A BARREL NEEDS to provide equivalent micro-oxygenation to a traditional barrel OF THE SAME VOLUME
The Squarrel square barrel shape was designed around the ability to use stave wood that would otherwise be destined for the wood chipper. In a cooperage, the most common piece of scrapped stave wood is ~15 inches. Though perfect for a Squarrel, it is too small for even a tradition barrel head and therefore doesn't have much use in the traditional barrel world.
