Cold pressed Bitter Orange oil is mobile liquid of dark yellow to olive-yellow or pale brownish yellow color. The odor is very peculiar, fresh and yet 'bitter' in the sense of 'dry,' but with a rich and lasting, sweet undertone.
This season I absolutely craved this wonderful oil. Maybe due to all the rain we had and no sunshine, however, this oil just made me smile and lifted my spirits!
There are notes that which remind one of bergamot, grapefruit and sweet orange, but overall, the odor is distinctly different from that of other citrus oils. It is a different type of freshness, a peculiar floral undertone which occasionally shows indolic notes and a comparatively good intensity.
Bitter Orange oil is used extensively in flavors where it forms the main ingredient in the 'orange sec' or 'triple sec' liqueur flavors.
For perfumes, the Bitter Orange oil finds use among the other citrus oils in all types of colognes, chypres, fresh fragrances, topnotes, aldehydic citrus bases, etc.
Blends excellently with Lavendin and Lavender, Rosemary, Clary sage, Oakmoss and Labdanum, Linalool and linalyl propionate, etc. Olibanum Resinoid is an excellent fixative for the volatile Bitter Orange oil.
