thats a good question and am curious also.It doesnt seem available,is it even? I definatly got some vanilla tastes from oak, how bout wine are these available for wine?
Because oak, specifically white oak, tastes good when used for aging alcoholic beverages while the others don't. White oak contains lots of vanillin and less of the oils, tannins and general furniture flavors that you might get from many other hardwoods.
In one of the Brewmasters episodes, they used cedar scraps from a surfboard making company. Doesn't sound very appealing to me, but it shows that rules were made to be broken. You can always try soaking some fruitwood chips in a glass of beer for 15 minutes to get an idea of how it might taste.
