The oil of our Guardians, and of everyone gifted a tree
Oil from your grove, every harvest.
Open your new oil each year, knowing exactly where it grew and who cared for it.
Guard a tree and it’s assigned to you after you join. Every harvest, two 500 ml bottles from its grove come to you, guaranteed, complete with tasting notes, the harvest booklet and postcards.
The 2026 harvest is underway. Guard or gift a tree by December 31 for this year’s oil.

Tasting notes.
Written by Fil Bucchino, international olive oil expert and panel taster, for that harvest.

What your care makes possible this year: the life counted in the groves, the people who work them, and the numbers behind your oil.

Between harvests, follow your tree in My Grove.
Where the name comes from
Both bottles are yours.
A restored Tuscan tree, harvested for quality, gives about two bottles of oil a year. That is the limit we work within, and the reason this oil can never be made in volume.
When we began, to sustain the restoration and the people behind it, one bottle went to the Guardian and one to the people who work the land. That’s where the name One Tree, One Bottle came from.
Today both are yours. Your care keeps the tree alive, so its oil is yours to open, share and cook with.
If you’d ever like one to go to the people who work the land, as it did at the start, write to us and we’ll make it happen.
The name is now One Grove Reserve: oil drawn from the grove where your tree stands.
Why it’s worth the wait
What goes into two bottles.
What happens in a lean year?
Your two bottles are guaranteed. Community Reserve, from trees we keep in our care rather than assign, exists so a hard season never reaches your table empty.
Every tree, every week.
Andrea Pagliai, master grower of the groves in our care, walks them with the team weekly to check the health of each tree, including yours.
The harvest date is always on your bottle.
The fruit sets it, not the calendar: each grove is harvested when its olives are ready. In 2025, Balatro began on October 8 and La Torre finished on November 6.
What never reaches your bottle.
Any extraction below our standard is set aside for kitchens and the local community. We accept the loss every time.
How fresh your oil is, in one number.
Peroxides measure how far an oil has begun to age. Across eleven harvests, ours average under a third of what the international standard allows.
Your grove’s oil
Each grove, its own harvest.
The 2026 harvest is underway. Until the new oil is in, each grove’s page shows its last harvest on record: the season, a tasting line, a pairing and the full lab record.
Your tree is assigned after you join, wherever one is available.
In their words
