Control of oak contribution is essential to achieving your desired wine style. Conventional calculations use surface area to measure oak contribution. The more accurate calculation is:

Surface Area x Penetration Rate x Time

This formula yields volume extracted, necessary to quantify pieces required for barrel equivalents.

Surface Area

Surface measurement (in2) is commonly used to compare oak extracted from barrels with alternatives. However, surface area alone is static and incomplete: contact time affects the amount of oak extracted from any surface area.

Barrel Equivalent Accuracy

Volume (in3) is the accurate measurement. Volume extracted is illustrated in the four-month snapshot at left.

Volumes for our products and conventional slats can be found in the Barrel Equivalents Chart.
