What percentage of the olive harvest winds up in martinis?

It's impossible to say exactly what percentage of the olive harvest winds up in martinis. There are several reasons for this:

* Olives for martinis are a tiny portion of the total olive production: The vast majority of olives are used for oil production, table olives, and other products.

* No comprehensive data exists: There is no centralized organization tracking the exact volume of olives used specifically for martinis.

* Martini recipes vary: Some martinis use olives, others use twists of citrus. Even those that use olives can use different varieties and amounts.

Therefore, any attempt to calculate this percentage would be purely speculative.
