The mystery is why the glass is long and thin, not why it is small, if I understood it correctly. You could have a glass with the same volume where you can use

The mystery is why the glass is long and thin, not why it is small, if I understood it correctly. You could have a glass with the same volume where you can use a normal spoon.

This would also make it spoil faster, more surface area exposed each time the glass is opened.

  I doubt the surface area matters. The volume of air and therefore oxygen you introduce every time you open the jar is the important factor. I would have thought that oxygen will dissolve in the liquid over a day or so even with a small surface area between the air and the liquid.

  This feels like one of those things where you're saying something that is maybe technically correct, so you can feel smart, but has no bearing on reality. A store near me sells capers in a short-and-fat glass jar (which even a large spoon can fit in easily). I've been able to leave those in the fridge just fine for 6 months with no noticeable change in quality... just like the tall-and-narrow glass jars. Based on my personal experience of these two jar shapes, any difference in spoilage-rate is imperceptible. What are you basing your "spoil faster" on?

Pretty sure that is most simply explained by prominence on a supermarket shelf. Something short and stubby is hard to see so people don't buy it, which is true in general, not just for capers. That's why you only really see that form factor on things like free sample jars and one shot jam jars that go into airplane meals, hotel buffet breakfasts etc- things where the manufacturer isn't fighting for prominence with other brands. That theory is also supported by the fact that big caper jars typically have the same aspect ratio as jars of other things (ie they aren't just a scaled up version of a small caper jar). At that size they have enough prominence on the shelf.
