Oak flame roasted 1-1/8″ New American Oak Cubes in a 20 lb bag ready for insert into a tank, or as individual cubes put inside a barrel. These cubes are more conventionally toasted, like the inside of a barrel, to offer a heavy char on the outside and more neutral wood on the inside. These are ideal for adding to barrels (as individual cubes) to exponentially increase the percentage of wood to liquid contact. The 20 lb bags are intended for tank insert applications.
For the most immediate impact on color, choose these char cubes. Compare to a standard char 4. Available in chars 1-6 by special request.
This test was conducted with roasted cubes. Toasted cubes may impart even more color in the same time.
