Tips on buying quality Oregano

Oregano is a herb, and often sold as flakes, which are extremely easy to dilute. In fact, most flakes sold as Oregano are actually Olive leave flakes! They look similar (slightly darker), have a similar weight, but zero oregano flavour and aroma. They’re simply much cheaper, and easier to mix and sell as “Oregano”. Selling whole dried oregano leaves is often not possible, because they’re much too light, and often used as flakes anyway. The one exception is buying fresh leaves.

In order to find the best grade dried Oregano, a good smell test is necessary. First, make sure your oregano flakes are very light coloured. Then, try to separate the darker coloured flakes from the light coloured ones. Both colours should smell the same, and should smell like Oregano! You would be surprised how easy it is to find “fake” oregano leaves this way.

If you have access to lab equipment, testing the volatile oil % is a surefire way to tell whether you have good oregano. New season Oregano should have at least 2.5% volatile oil, in rare cases reaching 3% or more if it has been extremely well kept and is very new from the best origin. Anything below 2% and you can be sure there has been some blending to keep costs low.
