Why aren't black olives packed in glass jars, like green olives?

Question

I've never have found black olives packed in resealable glass jars at my locality; they are always packed in non-resealable cans. But I can find green olives that are packed in resealable jars, but not in cans. Is the shelf life of black olives in glass jars a lot shorter than the shelf life is when they are packed in cans? Or is the flavor of black olives adversely affected by light exposure? Or is there some other reason that glass is not the preferred packaging material for black olives?

Answer 1

Olives don’t come to us in edible form straight from the tree. They have to be processed. Black and green olives (which can be the same olives—the color is how they end up, not necessarily how they grow) are processed differently.

Green olives are for the most part intended to be eaten raw. They are cured not cooked. This is, I believe, why they don’t typically appear on pizzas.

Canned black olives are literally cooked, like most anything else in a can. If you canned green olives, it would cook them, and that’s not what you want for a cured olive meant to be eaten raw.

If you tried to cook black olives in jars (the processing is done in the actual vessel in which the olives are sold), you’d break a lot of jars.”

Answer 2

Where I'm from (Ontario, Canada), we get black olives in glass jars too.

I guess you could go to the speciality section of a large grocery store and get the deli olives by weight in one of those clear resealable containers instead.

Resealable Jars

Answer 4

Try shopping at a fine food store or a organic store. They have
" olive bars" that you can purchase bulk olives. Then just put them in Mason Jars or other jars you may have.

Olives are better fresh, and can go bad over time!

Answer 5

Probably cuz a jar of black olives would look like a jar of turds.
