Rusty Tins

[anvil]

Hey mates is this normal.

I opened a tin of Squadron Leader last week and decided to put the foil insert and baccy in my tupperdor. When I pulled out the block of tobacco it exposed surface rust on the inside of the tin..

Is this because that particular brand of Tobacco is moist?
Is it safe to store in the tins for long periods?
TIA

I have a couple of tins unopened that I wanted to age for a few years, so any input would be appreciated.

Cheers

I think it depends on how long you plan to store the tins. Up to 5 years or so, you should be good, and the vacuum seal on the tin should be fine. Of course, the length of storage also depends on where the tin is stored. I've got 20-30 tins dated and in a small, slightly humidified plastic box.

I've seen lots of cases where old tins become rusted from being in over-humidified areas, and lose their vacuum seal. When I put my tins away, I don't ever break the seals, and check the humidity around the tins regularly, and make sure the seals aren't broken.

So, I think it just depends where you plan on putting the tins, the conditions around them, and how long you planned on aging them. Good luck!

More than likely what happened is the tin wasn't sealed properly. When a tin is sealed after a certain point it becomes very devoid of oxygen, thus the aging process of anaerobic bacteria breakdown begins. In order for rust to form the presence of oxygen is required, thus ferric oxide (or another metal oxide, depending on the metal) or rust is formed. When tins are sealed they are vacuumed sealed (removing oxygen) for aging, thus rust generally shouldn't form. It is also possible that the tin rusted before the tobacco was put in. If it were me I would still smoke it, your gonna burn it anyway.

Hope this makes sense.

I was only looking at a couple of years so I guess all will be OK. The seal on the Squadron Leader was fine, and I keep them in a cool dry place.
I only normaly Humidify the contents when I have cracked open a new tin.
Thanks for the reply mate.
