Table olives losing favor on California farms

Every few years the story repeats: a thin California table-olive harvest, and growers quietly bulldozing groves to plant something more profitable. It is not a mystery. Table olives carry a brutal cost structure — and understanding it explains why the crop keeps shrinking on the very land that once defined it.

A table olive and an oil olive look similar on the branch, but they live in different economic worlds. Oil olives can be shaken off, knocked about, and rushed to the mill — a bruise does not show in a bottle of oil. A table olive has to reach the jar whole and unblemished, because a bruised olive cures badly and looks worse. That single requirement — pick it perfectly, by hand, without a mark — sits behind almost every problem the table-olive grower faces.

The cost that never goes away

Hand-harvesting is the great weight around a table-olive grower’s neck. Picking the fruit gently enough to avoid bruising can swallow a large share of a grower’s gross return in a poor year — the labour bill alone can approach, and in a bad year exceed, the price the fruit fetches. When the sums are that tight, a single hard year, a low price, or a jump in the minimum wage can tip a grove from marginally profitable to loss-making. There is no clever pruning trick that fixes that; it is baked into the fruit.

The rival next door

Now put that beside the crop growers keep switching to. In California’s Central Valley — the only place that grows essentially all of the United States’ table olives — the neighbour is often the almond, mechanically harvested, long-storing, and for years extraordinarily lucrative. When the tree in the next field earns several times as much per acre with a fraction of the hand labour, ripping out olives is not sentimental cruelty; it is arithmetic. Every acre lost this way is hard to win back, because a new olive grove takes years to bear.

Alternate bearing and the shrinking base

Olives are also naturally alternate-bearing: a heavy year is often followed by a light one as the tree recovers, so harvest figures lurch up and down even before anyone touches an acre. Layer a steadily shrinking planted area on top of that swing and you get exactly the pattern the headlines keep rediscovering — a surprisingly small harvest, blamed on the weather, when the deeper story is fewer trees and a crop the market keeps under-rewarding.

What this means for a buyer

• Domestic table olives are expensive to grow for real reasons — cheap ones almost always mean imported fruit.
• A thin harvest is usually about acreage and economics, not just a bad weather year.
• Mechanisation is the industry’s long game — see our piece on the mechanical table-olive harvest.
• Supporting a named local grower is, in effect, paying for the hand labour the jar hides.

Table-olive economics: common questions

Why are growers pulling out table-olive trees?

Because hand-harvesting makes the crop expensive to grow, and rival crops like almonds often earn far more per acre with far less labour. It is an economic decision, not a farming failure.

Why can’t table olives just be machine-picked?

They bruise easily, and a bruised olive cures badly and looks poor in the jar. Machines have historically caused too much damage, though the technology is improving.

Where do US table olives come from?

Almost entirely California’s Central Valley, which grows essentially all of the country’s table olives. When that acreage shrinks, domestic supply shrinks with it.

What is alternate bearing?

The olive’s habit of following a heavy crop year with a lighter one as the tree recovers, which makes annual harvest figures swing up and down naturally.

Does this mean table olives will disappear?

No — but domestic ones stay costly, and more of the market fills with imported fruit unless mechanical harvesting closes the labour-cost gap.
