Inauguration by his Majesty the King of Morocco of an olive grove with Spanish technology
When a modern, GPS-planted olive grove of Spanish design opens in Morocco, it is a marker of something bigger than one estate: the spread of the super-high-density hedgerow, the innovation that industrialised the olive and made the New-World grove possible.
A royal ribbon-cutting at a GPS-planted, Spanish-engineered olive grove is a photo opportunity — but the technology behind it is one of the most consequential things to happen to the olive in a century. What is being inaugurated is not just a farm; it is a template. The super-high-density hedgerow orchard has, in a few decades, changed which countries grow olives at scale, which varieties dominate, and how the fruit gets from tree to mill.
What super-high-density really means
The traditional olive grove is a scatter of big, widely spaced trees, picked slowly by hand. The super-high-density (SHD) system plants small, closely spaced trees trained into a continuous hedge, exactly like a vineyard, so a straddle harvester can drive down the row and strip the fruit in minutes. The prize is speed and cost: olives can go from tree to mill in well under an hour, capturing the fresh, green character that slow hand-harvesting often loses. It is the industrial answer to the olive’s oldest problem — that good oil is a race against time.
Why the same few varieties keep appearing
The hedgerow only works with trees that stay small, crop young and heavily, and tolerate mechanical harvesting. Very few classic varieties fit, which is why SHD groves the world over lean on the same short list: Arbequina above all, with Arbosana and the Greek Koroneiki close behind. This is why a modern grove in Morocco, Chile, California or Australia can taste oddly similar — they are often the same handful of cultivars, planted the same way. The technology quietly narrows the world’s olive diversity even as it expands its output.
The trade-off worth understanding
SHD is a genuine advance: it makes clean, fresh, affordable extra virgin, and it lets new countries build serious industries fast. But there is a cost worth naming. The rush to a few machine-friendly varieties pushes older, characterful local cultivars — the ones that give a region its identity — toward the margins. The most interesting oils still come from those traditional varieties and groves. So enjoy good hedgerow oil for what it is, and also seek out the distinctive regional varieties the efficient orchard tends to leave behind.
| Traditional grove | Super-high-density hedgerow | |
|---|---|---|
| Trees | Big, widely spaced | Small, hedge-trained rows |
| Harvest | Slow, mostly by hand | Fast, by straddle machine |
| Tree-to-mill | Can be hours or more | Often under an hour |
| Varieties | Many, regional, characterful | A few: Arbequina, Arbosana, Koroneiki |
| Effect | Diversity, identity | Efficiency, uniformity |
| What opened | A modern SHD olive grove in Morocco |
|---|---|
| System | Super-high-density hedgerow, machine-picked |
| Star varieties | Arbequina, Arbosana, Koroneiki |
| Big advantage | Fast tree-to-mill; fresh, affordable oil |
| Hidden cost | Fewer varieties; local cultivars sidelined |
| Buyer’s move | Also seek traditional regional oils |
The takeaways
- The super-high-density hedgerow industrialised the olive like a vineyard.
- Its speed captures fresh, green character — good oil, made affordably.
- It relies on a few small, machine-friendly varieties (Arbequina and kin).
- The trade-off is lost diversity — so seek out traditional regional oils too.
Super-high-density olive groves: common questions
What is a super-high-density olive grove?
An orchard of small, closely spaced olive trees trained into continuous hedgerows, like a vineyard, so a straddle machine can harvest the fruit quickly.
Why does it matter?
It lets olives reach the mill within an hour, capturing fresh flavour, and makes clean, affordable extra virgin at scale — which is why new countries can build industries fast.
Why do these groves use the same few varieties?
Only trees that stay small, crop young and tolerate machine harvesting suit the hedgerow — chiefly Arbequina, with Arbosana and Koroneiki. Most classic varieties don’t fit.
Is hedgerow olive oil good?
Yes, it can be clean, fresh and well-priced. The catch is uniformity: modern groves worldwide often taste similar because they grow the same cultivars.
What is the downside?
The push to a few machine-friendly varieties sidelines older regional cultivars that give an area its identity — and often its most interesting oils.
A royal opening of a high-tech Moroccan grove is really a story about the super-high-density hedgerow — the innovation that turned the olive into a vineyard-style crop and let new countries build industries almost overnight. It makes fresh, clean, cheap oil, which is genuinely good news. The catch is sameness: the machine only likes a few small varieties, chiefly Arbequina, so modern groves worldwide taste alike. Enjoy the hedgerow oil, but hunt down the old regional cultivars too — that’s where the character lives.
