The best quality teak wood is grade A
Grade_A_teak_logsTeak wood is separated into three grades based on the quality of the wood. These three grades are known simply as grades A, B, and C. When a teak tree is mature, it will have a very dense core at the center of the trunk that appears darker than the surrounding wood. This is called the “heartwood” of the tree. Heartwood from mature teak trees of over 30  years old has a thick concentration of natural protective oil. Grade A teak is this mature heartwood, which is very dense, heavy, and saturated with natural oils that will protect anything made out of it from water damage and insects such as termites. Ideally, you want to look for furniture made from grade A teak.
Grade B teak is simply the heartwood from immature trees. It still contains some of the protective oils, but it is not as dense as grade A. Furniture made from grade B teak is not terrible, but it will not hold up outside exposed to the elements as well as furniture made from grade A teak. The lowest grade of teak wood is grade C. It is just wood from the outer sections of the trunk that lacks the natural oils which make grade A teak such a superior wood. Grade C teak will be characterized by an uneven, lighter color with widely spaced grains.
