In Focus: The Mission Olive
The Mission is the olive that started American olive growing. Carried up the California coast by Spanish Franciscan friars from the 1700s, it is the state’s oldest and only truly heritage variety — equal parts table olive, oil olive and living history, and capable of far more than the tinned black olive that made it famous.
Mission is named for the Spanish Catholic missions of California, where Franciscan friars planted it as they moved north from Mexico from the 1700s onward — up the chain from San Diego through Santa Barbara to Sonoma. Over two centuries it adapted so thoroughly that it is now treated as California’s own variety, even though its roots trace back to Spanish stock. The fruit is medium to large, ripening from green to a deep black, and it is genuinely dual-purpose: the basis of the classic American canned ‘black ripe’ olive, and a fruity, fairly robust, slightly nutty oil.
The friars’ olive
Few olives carry their history so plainly. The Mission is the living thread that runs from the eighteenth-century missions to the modern California industry — some trees are well over a century old, and a handful credibly claim mission-era ancestry. It arrived as Spanish stock and became, over two hundred years of California sun, something the state now calls its own. That is a rare thing in the olive world: a New World variety with genuine heritage, not just a European transplant with a marketing story.
The tin does it no favours
Here is the honest part. The canned black olive that made Mission a household name is one of the least interesting things you can do with a good olive. That uniform, jet-black, faintly sweet ring on a pizza is not the fruit tasting of itself — it is Mission (or another variety) picked green, lye-cured and bubbled with oxygen and iron salts until it turns black and bland. The process strips out almost all the character to deliver a soft, consistent, shelf-stable product. Blame the curing, not the olive.
Meet the real Mission
The variety is capable of far more. A naturally brine-cured Mission table olive keeps its fruit, its bite and a proper olive flavour. Better still, a fresh single-variety California Mission oil — fruity, a touch nutty, with gentle pepper and a harvest date on the bottle — is a small revelation, and a fair way into American oil. If your only experience of Mission is the ring from a can, you have not really met the olive at all. Seek out the naturally cured fruit or the fresh oil and taste what the friars’ tree can actually do.

Buying & using Mission
- Skip the tin — seek a naturally brine-cured Mission with real olive flavour.
- Better still, buy a fresh California Mission oil with a harvest date; treat it as a finishing oil.
- Its gentle, nutty character suits people who find fierce oils too much.
- Remember: the bland can is the curing, not the variety — the olive deserves better.
Mission olives: common questions
Is Mission an oil or table olive?
Both — it is genuinely dual-purpose. It is the classic American canned black olive and also gives a fruity, slightly nutty single-variety oil.
Where does the Mission olive come from?
It descends from Spanish stock brought to the New World, then planted at California’s Franciscan missions from the 1700s. Two centuries on, it is treated as California’s own heritage variety.
Why does the canned black olive taste so bland?
Because of the curing, not the fruit. Green olives are lye-treated and oxidised with air and iron salts to turn them uniformly black — a process that strips out most of the character.
What does fresh Mission oil taste like?
Fruity and fairly robust, with a slight nuttiness and a gentle pepper — very different from the bland tinned olive, and worth seeking out fresh.
How old are California’s Mission trees?
Some are well over a century old, and a few credibly trace back to the mission era — making Mission the state’s oldest and only true heritage variety.
If your only experience of Mission is the black ring from a pizza, you have not really met the variety. Seek out a naturally brine-cured Mission, or better still a fresh California Mission oil with a harvest date — fruity, a touch nutty, with gentle pepper. It is a small revelation, and a reminder that curing, not the olive, is usually what makes a tinned olive dull. The friars’ tree is living history; do not judge it by the can.
