Most winemakers prefer to add oak to their wines, and the best method is to age the wine in oak barrels. However, this isn't always possible for a whole bunch of reasons. Therefore, there is an alternative that can take the place of a barrel, and they are called cubs, beans, chips, and staves. Using a container such as the Oak Flavoring Tube, one can load it with American or French Oak cube or bean and lower it into a carboy, demijohn, and even a naked barrel, and within a few months, the oak will have infused its flavor in the wine. Always remember to be conservative when adding the oak alternatives and taste the wine frequently.
