eh, I used to collect a lot of them early in the 2000s, buying a case each year and aging them.
I found that 2 years was the breakpoint, and then they start becoming malt rocketfuel.
I quit buying cases in 2008, now I just buy 1-2 six packs and enjoy some now and some later, but oddly I seem to like it fresh the best.
I know I'm probably rare in that regard as most people prefer it well aged.
