Oak Barrels vs Sustainable Oak

Old Growth Trees

Barrels are made from enormous oak trees, often called “mighty oaks”. Most French stave logs are over 150 years old, and American stave logs are typically 60 – 80+ years old. Staves come from the choicest of old oak trees. These trees must be mature enough to produce clear wood. This clear wood primarily comes from a small portion at the lower part of the tree. It is at the trunk, where there are limited branches and thus fewer knots. The rest of the tree has much less value and is sold in low-end products.

Tree Waste

Conservatively, only 20 – 25% of the White Oak tree can be used for barrel making. Only two 225 liter barrels can be manufactured from the heartwood of a French Oak of 80 120 years old.  Only two 225 liter barrels can be manufactured from the heartwood of a French Oak of 80 – 120 years old. Given the tight specifications for making barrels, most of the log is discarded and cannot be used in making staves. To avoid leakage, a sawyer must cut staves that are clear (without knots) and avoid the cambium (sap) layer. Furthermore, only a certain grain orientation is used (quarter sawn/rift).

Most of the log does not meet the demanding specifications, and ends-ups in low-value products such as railroad ties, low grade lumber, pallets, chipped for fuel, or is used as animal bedding.  American White Oak logs are more efficient, but still only a small portion of the tree is used.

Barrel Inefficiency

Approximately 80% of the barrel is not used to impart flavor. The above photo shows the penetration into the oak after 10 years. This well illustrates that less than 20% of the barrel is used to impart flavor.

The design of barrels has changed little since their invention by the Celts in 350 BC. Only a small portion of wine/spirits actually comes in contact with oak. Most staves are manufactured at just under 1-1/4” thickness (prior to surfacing).

However, barrel penetration after 4-10 years rarely reaches over a 1/4” depth (and by the 4th year most of the barrel’s extractives have leached). This means, with imparting flavor, 80% of the wood in barrels is completely wasted, and that 80% of the liquid does not even come in contact with oak.

Sustainable Oak

Seeking stewardship of our dwindling old growth oak forest, and using groundbreaking science to reduce the carbon footprint, Soluble Oak offers an environmental solution which doesn’t sacrifice quality. Given the molecular complexity of oak, traditional extraction methods have been substandard.

Please consider the environment & switch to using Sustainable Oak.
