AI Thread Summary
The discussion highlights that the U.S. is not a member of the International Olive Oil Council (IOOC), making it the only major olive oil producing and consuming nation outside this organization. As a result, the U.S. lacks the stringent grading system of the IOOC, which includes classifications like extra-virgin and virgin olive oil, leading to potential mislabeling and quality issues in American markets. The USDA's grading system is less rigorous, allowing for inferior oils to be marketed as "extra-virgin." Consumers are advised to be cautious when purchasing olive oil, as the term "extra-virgin" may not guarantee high quality. Ultimately, taste remains the most reliable indicator of olive oil quality, with many producers adhering to international standards despite the lack of regulation.

If you love to cook like me and use olive oil all the time, you may find this a bit shocking. I just found out that the US is not a member of the IOOC (international olive oil council) and is the only major olive oil producing and consuming nation not in it. The IOOC grades olive oil as

-Extra-virgin olive oil comes from the first pressing of the olives, contains no more than 0.8% acidity, and is judged to have a superior taste. There can be no refined oil in extra-virgin olive oil.

-Virgin olive oil with an acidity less than 2%, and judged to have a good taste. There can be no refined oil in virgin olive oil.

-Olive oil, which is a blend of virgin oil and refined virgin oil, containing at most 1% acidity. It commonly lacks a strong flavor.

-Olive-pomace oil is a blend of refined pomace olive oil and possibly some virgin oil. It is fit for consumption, but it may not be called olive oil. Olive-pomace oil is rarely found in a grocery store; it is often used for certain kinds of cooking in restaurants.

-Lampante oil is olive oil not used for consumption; lampante comes from olive oil's ancient use as fuel in oil-burning lamps. Lampante oil is mostly used in the industrial market.Since the US isn't a part of the IOOC, this system doesn't apply. The only grades the USDA has for olive oil are Fancy, Choice, Standard, Substandard. Oil is graded based on acidity, absence of defects, odor and flavor. This means the US is a dumping ground for old and mislabeled oil from all over the world. As a result, that "extra-virgin olive oil" really means nothing in the US, it can be applied to any grade of oil. So be weary of paying extra for that extra virgin/virgin olive oil, cause it may not be so great after all.

Look for the key words "first cold pressed." Not "cold pressed" but "first cold pressed." THis scam has been going on for decades.
 
While I do use domestic olive oil for cooking, I only use italian or greek olive oil for dipping and dressing.

To the credit of many olive oil producers in the US, especially the well-known ones in California, they do stick to the international standards even if it isn't required. Still, the ultimate guide is still taste.

Zz.
 
Yeah, I pretty much rely on my tastebuds. I don't really care what grade it technically is (provided it's one of the edible grades) as long as it tastes nice and flavorful to me.
 
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...
Thread 'My experience as a hostage'
I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
