olives

by Barbara Hill

How can I tell when my olives are ready to be picked and cured?

Harvest times vary depending upon the olive variety, region, and overall weather conditions. In California, the first phase of picking generally begins in mid-September when fruits have reached the “green-ripe” stage. These olives have attained their mature size, are an even yellow-green in color, and release a creamy-white liquid when crushed. As the ripening process continues, the green hue changes to a mottled reddish-brown, and in December, final harvests gather the fully ripe “naturally black” olives.

Green olives tend to be more dense, firm, and bitter than black olives, but the texture and flavor of any olive depends upon the method and length of the curing process. A quick nibble of a just-picked fruit will make abundantly clear why curing is necessary. Oleuropein, a bitter compound found in the skin, may be effective at repelling pests, but millennia ago, clever humans developed a variety of methods to leach away the offending substance, with delicious results. Processing with lye is the fastest way to accomplish this, but care must be used with this highly caustic substance. Oil-, water-, brine-, and dry-curing techniques are slower but safer, and all are excellent methods for the home gardener.

For more information see UC ANR’s publication Olives: Safe Methods for Home Pickling (pdf).
