I’m one of the many who shopped to excess during the EU TPD scare, and still have a few lifetimes worth left.

My bulk and frankenblends are stored in one litre clip top glass jars. I also have smaller screw top jars for single blends in smaller quantities. They don’t keep perfectly moist, but I always rehydrate a snuffbox when I full it (not the parent jar), and have suffered no significant loss of scents.
<p style=”text-align: left;”>Factory tins from everyone except Toque have rusted over the last decade or so. Not all, but enough to rule that out as long term storage. I need to transfer the rest of my tinned stash to Mylar pouches (air squeezed out but not vacuumed) at some point. From there, it will go into the small screw top jars.
Toques not bought in economy pouches can all stay in their tins. Although the 10x10g tins (100g) are almost as expensive as 6x25g tins (150g), I prefer the smaller tins because they are very pocketable. I don’t buy often these days due to having such a big stash, but do like to keep a few of those 10g tins handy.
