I don’t understand why people are trying to age snuff that has been already aged? Please explain!

Why are people trying to age snuff when snuff is already aged from what Alex wrote?

60 to 100+ is a very long time.

Okay! 60 to 100 years is very long

That is strong confidence in your product. I’ll be dead by the time anyone uses this but hey they’ll really enjoy it alot.

Ageing generally allows improvements of a product as snuffgrinder says. A good wine can become awesome. An unbalanced spirit can become balanced.
