Olive oil comes in dark bottles, best of it in foiled bottles to completely avoid light exposure, I buy mine in enormous cans
It's all about luck though for me, most of the year I use my own olive oil, it comes from Liguria Basilicata or Salerno and it's made the old way by friends I know well.
You might buy online and get amazing products from Italy, Spain, Greece, just choose a place, or if you're from California go and buy local because that's the best thing people can do for their own health and the sake of economy.
PS I'd never buy/use Monini, Bertolli, or many other brands out there, unless they are selling overseas stuff which is not available here. Spinelli is good. No offense intended, sometimes it's all in the tastebuds.
No limits, only my will and the worlds I build.
