Well they grow almonds near Sacto, do they not? (I live in Contra Costa Co...inland, it gets pretty hot)
You may, however, need “central-valley” type hot, not just “East Bay” hot. Frankly I don’t know, but how cool would having your own olive trees be? Harder than buying a bottle or can and uncorking it, clearly.
Just as an aside to the article, I was in Greece in the mid-70’s, unfortunately haven’t been there since, but it was absolutely one of the more delightful countries of the many I’ve been to.
I don’t believe it would be hot enough where I live.
Yes. Not only do the grow olives in several places from Sacto to Porterville, there is even olive oil made in said areas, particularly from the arbequina olive. Most of the Cali olive oil I have had was disappointing. Typically greasy, with too much nuttiness in the taste. You can usually get it at Williams Sonoma.
