I wish there were still coffee sold in the old fashioned cans , without the peel off seal. Even the store brands (eg Great Value) are using the pull off inner seals. Maybe it doesn't make any real difference, but I can't help but feel that cans that require a can opener will keep stuff fresher and longer than the kind with an attached means of opening.
Interesting to study the freshness between coffee in all-steel cans and the plastic tubs with mylar/plastic seals. I’d bet on the steel, but I might be surprised.
I've got about a dozen of the bricks. They stack nicely.
