What honey barrels? Maker's does extra work (rotating barrels) to ensure that there are as few outlier (honey/otherwise) barrels as possible. And then they dump them all at a fairly young age, whether or not a particular barrel is one that would continue to improve.

Of course some barrels end up better than others, but there probably aren't a ton of real standout MM barrels, thanks to differences from the way everyone else does things.
