Yes! I knew there were other foods and drinks that did it, but couldn't remember which offhand.

I kept thinking to myself, "...Bourbon Barrel-aged Chocolate, maybe...?"

MYTHBUSTERS did this to test the theory - they claimed it was "Busted" because filtration doesn't make bottom-shelf vodka taste as good as top-shelf, but filtering it five times through a Brita/Pur type filter does make it taste better to both a vodka "expert" and to Jamie Hyneman. (Kari Byron picked the unfiltered bottom-shelf "control" as second-best and top-shelf as worst, to everyone's amusement!)

Sorry for the crappy copy, but since Discovery Channel now owns WB they're charging for copies of MYTHBUSTERS....

And once the bourbon barrels can no longer be used for alcohol, they can age coffee in it!

I'm serious - Starbucks Reserve sells a coffee with beans aged in a bourbon barrel. It's actually really good...unfortunately it's also insanely expensive (I bought a half-pound for $45 as a treat!).
