Why is Olive Oil so GOOD for you?

Because it's one of the only natural foods that contains Polyphenols & Antioxidants, which help prevent oxidation and cell break-down in your body.  In other words, Extra Virgin Olive Oil helps your body last longer, and work better, making it a true 'super food.'

Check out this article where UC Davis is linking EVOO to: "Olive oil as medicine: the effect on blood lipids and lipoproteins."

When does the olive bloom start?

Usually around the beginning of May, however some years, it can be 2-3 weeks early.

When are olives harvested?

Each year the olive harvest starts in late September to early October for table olives, while harvest for olive oil starts a few weeks later in mid October when the olives are more mature, containing more oil and richer flavor.  For Bozzano, the heaviest harvest months are November and December.

What does it mean to be certified organic? 

Organic is a labeling term that indicates that the food or other agricultural product has been produced through approved methods that integrate cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance, and conserve biodiversity. Synthetic fertilizers, sewage sludge, irradiation, and genetic engineering may not be used.


Bozzano Olive Ranch is certified Organic by Global Culture & the USDA.

How should olive oil be stored? 

Away from light and heat, because these can damage olive oil fairly quickly (within days in extreme situations).  So storing it in a cupboard would be best, with temperatures under 80 degrees ideally, and above 50 (F).  We don't recommend storing EVOO in the fridge because that could compromise the quality.  Oxidation is the third way olive oil is damaged, however this is inevitable, and occurs naturally over time.  Typically over 6 months from when you open the bottle.  So if you'd like the best flavored olive oil, consume it within six months of purchasing, and within two years of it's harvest date.  That said, EVOO has the most flavor and health benefits when consumed within the first 12 months of being produced, this is why we make it a goal to start selling the new year's harvest, of fresh oil, in January of each year.
