Re: Real vs Fake
That is real. If you want it fake you add wood shavings activated by either flash-microwaving them for 30seconds or running a gas lamp over them and leave the maturing "cask" at ~ 30+C for two months.
Also well-known in the wine world, where it makes the difference between a subtly oaky wine matured in oak barrels, and the headache-inducing super-oaked cheap stuff that is swilled around in stainless steel vats with oak shavings. "two buck chuck" being an example.
