Olive oil is one of the most-faked foods in the store, and the kosher aisle leans on a handful of big certified labels blended from 'several countries.' These are independent California growers who press their own fruit and name their hechsher. Independent kosher-certified vinegar is genuinely thin — we've listed what we could verify rather than pad it.

The Bariani family emigrated from Lombardy to Sacramento in 1990 and started pressing oil from the olives around their house. They now stone-crush and cold-press their own Yolo County fruit within a day of harvest, decant it unfiltered, and bottle it in dark glass to slow oxidation. The extra virgin olive oil is certified OU kosher.
Why it isn't on AmazonStone-milled, unfiltered oil from one family's dated harvest is a different food from the blended commodity oil that lists three countries on the back label.
See it at Bariani Olive Oil →Jesse Schwartz's Berkeley company has made raw, unheated 'alive' foods since 1979 — nut butters, olives, and a California extra virgin olive oil — kept below heat thresholds to preserve the raw character. The line is kosher-certified under Sunrise Kosher, the Vaad Hakashrus of Northern California, and they carry olives and a vinegar alongside the oil.
Why it isn't on AmazonOil pressed and handled to stay raw is a small-maker choice you order direct; it isn't formulated for a warm grocery shelf.

Add your brand →Pure pressed olive oil is inherently kosher, but certification still matters. It confirms the bottling line wasn't shared with non-kosher products, that no non-kosher additives or flavorings went in, and — for infused oils — that the added ingredients are clean. A named agency like the OU verifies the whole operation, not just the olives.
An estate oil comes from one grower's fruit, pressed soon after harvest and often dated by pressing, so you can taste a specific place and year. Much commodity oil is blended from multiple countries, older, and sometimes cut — olive oil is among the most adulterated foods sold. Buying from a grower who mills their own fruit is the surest way to get the real thing.
Heat and speed raise yield but cook off flavor and can degrade the oil. Cold-pressing and old-style stone milling keep temperatures low, protecting the peppery, grassy notes and the antioxidants that make good oil taste alive. It's slower and lower-yield, which is why small producers charge more for it.
Keep it away from heat, light, and air — a dark bottle in a cool cupboard, tightly capped, not next to the stove. Good oil is a fresh product with a real clock on it; use it within a few months of opening. If it smells flat, waxy, or like crayons, it's oxidized and past its point.
