Cubes have a longer contact time than traditional chips do, which make them better for long-term aging of wines and beers. Also, longer contact time means longer extraction of flavors (3-6 months), which leads to a more complex combination of flavors. Chips are usually done giving flavor after a week, there by contributing a harsh, flat oak flavor.
