I have few olives, only got a handful of trees here and picked just a big one, was late for the harvest due to extra time spent in The Netherlands and many olives were either half eaten or there were insect(s) holes inside.

100 trees is an awesome amount. A good problem indeed ;<)

I am gonna try all three techniques, including topping off a jar or two with olive oil ( both one with salt and warer and a plain one ).

Cheers for your advice!
