This charming Spanish hacienda estate and olive-processing plant in Ontario has been open to hungry visitors since 1894. It offers free tours and gobs of mouthwatering Graber olives for sampling and sale. The best time to go is late fall or early winter, when the packing process is in full swing. Unlike other brands, Graber's olives are pitted only when they're completely ripe, and some of their varieties are only available on-site. A recommended day trip for couples and food lovers who want to change up their winery routine.
