The Characteristics of Lavender Oils from Eastern Europe
By: Erich Schmidt, Kurt Kitzing GmbH
Lavender oil (ex. Lavandula angustifolia Mill.) is produced commercially by a number of countries: France (the main supplier), Bulgaria, Moldova, Ukraine and Australia. The oils from each of these regions possess distinctive aroma characters, which range from the fine, flowery, fresh notes in the French oils to herbal, woody and camphoraceous with fatty notes in the Australian oils. Herein, it will be shown that these differences in aroma can be translated into a visual form (map) that assists comparisons with chemical analysis data.
