The present invention relates to an apparatus and method for shaving the inside of barrels. In particular, the present invention relates to reconditioning used wine barrels by shaving the inside surface to a predetermined depth, ready for re-crozering, toasting, and re-use. Conventional shaving methods typically involve routing the internal surface by hand, but this technique is problematic in that it is a very slow process, the quality of the wood is often adversely affected, and there is no way of ensuring that the surface will be shaved to the same depth across the entire surface. Therefore, the resultant internal dimensions of the barrel are not reflective, relatively, of the original barrel surface. The apparatus of the present invention includes a scanning device adapted to scan the internal dimensions of the barrel, and a cutting device adapted to shave the internal surface to a predetermined depth relative to the scanned internal dimensions.
