How long will American Plain Scotch ‘keep’ in the 1.15 oz. containers it comes in ? Are the containers paper/cardboard ?

Only the Conwoods are cardboard, the Swisher and US Smokeless are plastic. I’d say they last near forever.

I have a WE Garrett that’s 25 yrs old. Tastes GREAT!

just keep out the air and rust. Keep dry too!
