... and boy, am I glad I did.
Over the years I;ve purchased numerous brands of oregano, from commercial-supermarket oregano to oregano sold by spice shops, like Penzeys, etc. None of those oreganos had the deep flavor and robust aroma of what I used tonight. They are lifeless by comparison.
I bought a Calabrian oregano and a Sicilian-grown oregano. They are similar, although the differences are subtle. While I didn't cook a dish using these herbs, I mixed an equal amount into equal amounts of passata and warmed them both to the same temperature. It was hard for me to detect much difference, although the Sicilian seemed a skosh sweeter. More comparisons are needed.
One thing is clear, I will not go back to those other oreganos. However, it would be interesting to compare these to similarly-packaged Greek oregano.
