Final Thoughts:
For the freshest experience, look for products labeled “fancy grade” or “extra fancy” (whole leaves rather than heavily crushed), non-irradiated, and recently packed. Thyme from Mediterranean origins often has the most authentic, pungent profile. Check current Amazon/Walmart best-sellers or specialty sites like Mountain Rose Herbs for the latest stock and reviews, as preferences can vary by batch and personal taste.
