Torrefied Adi Red Spruce

Thermally aged (torrefied) Red Spruce tops

  Botanical Name: Picea rubens
  Adirondack or Red spruce is one of the most difficult woods to obtain in decent quality. Considered by many to be the holy grail in top wood. Red Spruce has a very high velocity of sound, and has the highest stiffness across and along the grain of all the top woods. Like Sitka, it has strong fundamentals, but it also exhibits a more complex overtone content. Tops made out of red spruce have the highest volume ceiling of any species, yet they also have a rich fullness of tone that retains clarity at all dynamic levels.

   The Torrefication processas explained to us involves drying the boards to remove the moisture. Then removing the oxygen and drying at a higher heat, followed by slow cooling and reintroductiom of moisture. The entire proceess takes about 3-4 days.
