I have a tin on the way that has a January/2011 date on it. Has anyone tried this stuff when it's a few years old? I enjoy it young but have always thought that it would age really well, which is why I am cellaring so much of it. When this 2011 tin comes in, I will have to decide whether I give it a whirl right away, or whether I let it age a bit longer, and I am struggling with that decision.
