Israel: Sharp drop in olive harvest
A harvest that comes in at a fraction of the previous year sounds like a catastrophe and is usually arithmetic. Olive trees alternate, drought compounds it, and a bad week during flowering can finish the job. Here is how the mechanism works, and what it does to price.
Every few seasons a producing region announces that the olive crop has collapsed — a half or a third of the previous year — and the reporting reaches for a single villain, usually drought. The truth is more layered and more interesting, and understanding it tells you a great deal about why olive oil prices behave the way they do everywhere in the world.
The tree’s own rhythm comes first
Olives are strongly alternate bearing. A tree that carries a heavy crop spends its reserves on fruit and sets few flower buds for the following spring, so a big year is normally followed by a small one whether or not the weather cooperates. In a region where most groves are traditional and rainfed, and where pruning and thinning are not aggressive enough to smooth the cycle, whole districts can swing in step. Half the drop in a bad year may simply be the trees doing what olives do.
What makes the swing worse is that stress in one season is paid for in the next. A drought year does not only reduce that year’s fruit — it weakens the tree, reduces shoot growth and cuts the wood that would have carried the following season’s flowers. That is why a poor harvest is so often blamed on last year’s drought rather than this year’s weather, and why irrigation, where it exists, is as much about next year as this one.
The two weeks that decide the year
The most fragile moment in the olive year is flowering, in spring. The tree produces an enormous number of flowers and sets fruit on a tiny fraction of them, and that fraction is decided by conditions over a very short window. A hot, dry wind during flowering desiccates the flowers and the crop is gone before anyone has thought about harvest. Heavy rain at the same moment washes pollen away with much the same effect. Insufficient winter chill beforehand can disrupt flower initiation altogether.
This is why forecasts made in spring are unreliable and why growers are so fatalistic about them. By flowering the die is largely cast, but nobody can count what they cannot see, and the true size of the crop only becomes clear as the fruit sizes up through summer.
| Factor | When it acts | What it does |
|---|---|---|
| Alternate bearing | Set by the previous year’s crop | A heavy year suppresses the next ; the base rhythm |
| Drought | Previous and current seasons | Weakens the tree, reduces bearing wood and fruit size |
| Flowering weather | Two to three weeks in spring | Hot dry wind or heavy rain can destroy fruit set |
| Winter chill | Mid-winter | Insufficient cold disrupts flower initiation |
| Olive fly | Late summer to harvest | Damages fruit, raises acidity, downgrades the oil |
| Harvest labour | Autumn | Shortages delay picking and cost quality, not volume |
Why prices rise later than you expect
Local prices in a short year rise, but rarely in proportion, and rarely immediately. Oil from the previous harvest is still in tanks, and holders release it into the shortage — which is precisely what stocks are for. The rise arrives with a lag, and it depends heavily on whether the shortage is local or regional. A poor year in one small producing country against a normal Mediterranean crop means imports fill the gap and prices barely move. A poor year across the whole basin, when the big producers are also short, is when the world price moves sharply.
There is a quality dimension too, and it is the part buyers should watch. In a short year the pressure to harvest every last olive, including damaged and fly-struck fruit, becomes intense, because the fixed costs of the grove have to be recovered from less fruit. That is exactly when free acidity creeps up and the share of oil making the extra virgin grade falls. Scarcity years are good years to buy on a named producer you trust rather than on price.
What to take from a bad harvest year
- Do not read one bad year as decline. Alternate bearing means the following season is often strong.
- Watch the whole basin, not one country, if you want to predict prices.
- Expect quality variance to widen in a short year, not just volume to fall.
- Buy from producers who state a harvest date — in scarcity years, old stock gets repackaged.
- Ancient local varieties are worth seeking out : Souri, grown across the Levant for millennia, gives a robust, peppery, characterful oil.
Harvest failures and prices : common questions
Why do olive harvests vary so much year to year?
Mainly because olives are alternate bearing — a heavy crop depletes the tree and suppresses the next year’s flowering — compounded by drought, flowering weather and pest pressure.
Does drought affect the crop immediately?
Both immediately and with a delay. Water stress reduces fruit size in the current season and weakens the wood that would carry the following season’s flowers, so a drought is often paid for twice.
Why does a small harvest not double the price?
Because carried-over stock from the previous year cushions the shortage, and because prices respond to the whole Mediterranean supply rather than to one country. Sharp price moves need a basin-wide short crop.
Does a poor harvest mean poorer oil?
It often means more variable oil. Pressure to pick every fruit, including damaged and fly-struck olives, raises free acidity and reduces the proportion reaching extra virgin grade.
What is Souri?
An ancient Levantine variety grown across the region for thousands of years, hardy and drought-tolerant, giving a robust, peppery, phenol-rich oil. It is one of the oldest continuously cultivated olives anywhere.
The mistake I see buyers make in a short year is to chase price. When a crop halves, the cheapest bottles on the shelf do not stay honest — the pressure to fill contracts with whatever is available is enormous, and it shows up as tired oil in nice packaging. A scarcity year is exactly the moment to shorten your supply chain: buy less, buy from a name you know, and buy the current harvest. Then wait. The next season is usually the tree’s big year, and it will be a good time to fill the cupboard.
