I've often read that tobacco tastes better after it has rested for a couple of weeks. That's been my experience too, especially with Virginia blends. No lesser authority than GL Pease had made this point in one of his columns. What is the explanation for this? Is it like wine that needs to oxygenate? Is it like freshly roasted coffee beans that needs to off-gas? Is it just that the tobacco is drier? I generally jar tobacco after I've had the first bowl but maybe I should leave it in the opened tin for a couple of weeks first.
