BONDOLIO OLIVE OIL CO. | Winters | Each year in December, there's a one-day opportunity to visit this boutique olive farm and mill during their Holiday Open House. It's a chance to see an orchard where the trees grow naturally (unlike super-high-density plantings). The trees here are pruned so the olives can be harvested by hand, and you can see how each tree trunk divides into three-to-four primary branches that hold all the leaves and fruit.
