The Race Against Time: What Happens When Olives Wait
I can still hear my father's voice echoing across the grove.
"Move faster! The olives aren't waiting for us!"
I was just a kid back then, running between the trees, more interested in chasing lizards than picking olives. My job was simple—spread the nets under the trees, help gather what fell, and try not to trip over my own feet. But no matter how fast I moved, it was never fast enough for him.
I thought he was just being grumpy. Another long day, another early morning, another push to get the job done. I'd roll my eyes and mutter under my breath.
But I was wrong. Dead wrong.
He wasn't being impatient. He was protecting something I didn't understand back then — something that would take me years of farming to truly appreciate.
Every hour counts after an olive leaves the tree. Not just for tradition. Not just for productivity. But for the actual, measurable quality of the oil inside that bottle you're going to pour over your dinner.
And here's the nerdy, behind-the-scenes truth that blew my mind when I finally got it.

The clock starts ticking the moment the olive is picked
Here's the simple truth: the best olive oil in the world starts with olives that are pressed fast. Ideally within hours — some say 6, others push for 12. My father would say "as fast as humanly possible," and he wasn't wrong.
At Papa's Grove, we press our olives within hours. Why? Because once that olive leaves the tree, it starts a slow but steady journey downhill.
What actually happens at the molecular level?
This is the science part — bear with me here, because it's fascinating.
When an olive is picked, it's still alive. The cells are intact, the enzymes are active, and the oil inside is stable and protected. Think of it like a fresh apple — perfect one day, starting to soften the next.
But delay pressing, and a few things start to happen. And here's where the science gets genuinely interesting.
1. The oil starts to oxidise.
Oxidation is just a fancy word for what happens when oil meets oxygen and starts breaking down. You've seen it before — cut an apple and watch it turn brown. Same idea.
When olives sit around, their natural enzymes start breaking down the fruit. Free fatty acids increase as quality degrades, and these are the enemies of good oil. One study found that olives left waiting showed clear signs of oxidation the longer they sat. A few hours? Fine. Overnight? Noticeable. A day or two? You're losing quality you can never get back.
2. Heat speeds up the damage.
If olives sit in bags or baskets, they start to generate heat. And heat? It's not kind to olive oil. Temperature affects the compounds that give olive oil its flavour and aroma. Higher temperatures before pressing can actually reduce those fresh, grassy, herbal notes we love, while increasing compounds associated with off-flavours.
One study found that cooling olives before pressing reduced the presence of compounds linked to flavour defects. In other words: keep them cool, keep them fresh.
3. The good stuff starts disappearing.
Here's a fact that stopped me in my tracks: antioxidants slowly degrade over time. One study showed that total phenolic compounds can decline significantly during storage, and this process accelerates with higher temperatures and oxygen exposure.
Now imagine that process starting before the olives are even pressed. Every hour of delay is a small, irreversible loss.
4. Bruising damages the fruit.
This one's simple: damaged fruit doesn't make good oil. When olives get bruised—from sitting too long, from being piled too high, from rough handling—the cells break down and oxidation starts. Research shows that bruised olives have higher levels of oxidation and lower quality oil. Less bruising means better oil. It's that straightforward.

Look, I'm not a scientist. I'm a farmer who's spent decades watching what happens when you treat olives well — and what happens when you don't.
And here's what I know: a few hours can make a real difference. Not a guarantee of perfection. Not a promise of the best oil ever. Just a simple, honest fact — fresher is better.
The "waiting" trap
Here's the thing I learned from my father, and from science, and from years of farming: there's always a temptation to wait.
Wait until you have enough olives to make the trip to the mill worthwhile. Wait until you have time. Wait until the weather improves.
And sometimes, waiting is unavoidable. Maybe the mill is backed up. Maybe the weather turns. Maybe you just can't get to all the trees in one day. That's farming. That's life.
But here's what I've come to understand: every hour of delay is a small compromise. The olives aren't getting any better—they're slowly, gradually losing some of what made them special. It's not that they become bad oil overnight. It's that they become less than they could have been.
Research suggests that pressing within 24 to 48 hours is still acceptable. Some studies even show that hand-picked olives pressed within 24 to 36 hours can yield oil that oxidizes more slowly than olives harvested by machine or over a longer period. So it's not about perfection — it's about doing the best you can with what you have.
For us, that means pressing as fast as we reasonably can. Not because we're chasing some impossible ideal, but because we know that every hour counts. And we want to give the olives — and you — the best possible chance.
What this means for you
When you open a bottle of Papa's Grove olive oil, you're tasting olives that we pressed as quickly as we reasonably could. Not because we're chasing perfection, but because we believe fresh is better.
We don't aim for perfection — we aim for honesty. We press within hours when we can. We don't let olives sit in bags overnight if we can help it. And we do our best to get the fruit to the mill while it's still at its peak.
That peppery kick you sometimes get? That's the polyphenols — the good stuff — still largely intact. That grassy, vibrant flavour? That's the fruit, still relatively fresh. These are signs that the oil hasn't been compromised by unnecessary delays.
We can't promise every bottle will be perfect. Nature doesn't work that way. But we can promise that we've done everything in our power to preserve what the tree gave us.
My father may have yelled at me to move faster, but now I understand why. He wasn't yelling at me. He was yelling for the olives.

Our current harvest Koroneiki, Manaki, and Balanced blend were pressed within hours of picking. Fresh, peppery, and alive—just the way it should be.
