Torrefaction is a form of controlled heat treatment that can be seen as a way to speed up the natural ageing present in wood that is decades old.

The process drives away the volatile oils, sugars and resins that would normally vacate the wood naturally over a very long period. This has the effect of making the wood very much more hydroscopic than new wood and therefore much more stable where the instrument may be subjected to extreme variations of temperature and humidity.

The grading system as detailed below evolved in the tonewood department of Timberline many years ago as an attempt to clearly define quality aspects of guitar back and sides sets. I hope that it will be easily understood and that you will excuse me for using a system unique to this company.

AAA – Quarter sawn wood or nearly so.

AA – Wood that is quartered to one edge, (where the centre joint of the back will be ), gradually straying from the quarter ending up slab sawn at the opposite edge.

A – Wood that is slab sawn, the main slab sawn area being approximately half way across the board.

* - One or more asterisks may be added to the grade mark to indicate wood that is aesthetically more pleasing or desirable by virtue of colour, intensity of figure or fineness of grain.
