It has a bitter flavor.

sweetness and rich-herbaceous notes. As a
modifier in heavy florals it may be used sparingly, but it is not often found in a perfume laboratory. | | Preparation | By esterification of nerol with isovaleric acid | | Aroma threshold values | At 1.0%: sour, sweaty with floral rosy undernotes, and a bergamot citrus nuance and fruity notes of blueberry, cranberry, apple and grape. | | Taste threshold values | Taste characteristics at 5 to 20 ppm: fruity, rich floral and slightly citrus-like with berry, waxy nuances of
blueberry, fruity notes of apple, grape, peach and apricot |
