I'm now reconsidering this stance. I've been delving into my stash, which goes back 10 years. Seems I'd forgotten just how spectacular old Bigfeet are when tasted alone. Certainly lacking in hop flavor and aroma, but all kinds of crazy complexity going on between malt and hop bitterness.
This makes me rethink how to do Bigfoot verticals. In the past, mimicking how one would do it with wine, I've always proceeded newest to oldest-- best for last, I suppose. But given how much young Bigfoot blows away the palate with hoppiness, masking the subtleties and complexities of the older beers to follow, from now on I'll go oldest to youngest.
Perhaps this is where to insert "Well, duh!", but it was a bit of a revelation to me.
