A few years back, I smoked a few bowls of Three Nuns from WW2. Some of the topping had dissipated, but it was spicier than the versions I smoked from the 1980s until Orlik swapped out the perique for Kentucky.
New Year's of 2018, I opened a 2001 tin of Three Nuns, and compared it with Doblone d'Oro. The former lost a touch of topping and it seemed to me the the latter tasted more like aged Thee Nuns rather than the fresh version that I was used to, though the perique was a half step less than the three ladies were.
