Цікавий факт
Of the whole blackcurrant plant, the most aromatic part is the bud rather than the fruit. The smell of the blackcurrant thiols depends on their concentration: at low levels it is a pleasant blackcurrant odour, and at higher concentrations it becomes distinctly more feline.
Отримання й хімія
Спосіб отримання
Blackcurrant bud absolute is made from frozen buds by solvent extraction. Harvesting begins at the end of November and continues throughout the winter until February. The plant must be dry to be picked, so it is harvested in the afternoon to avoid the morning dew. The plants are then cut and the buds separated from the branches. The buds are first extracted with a volatile solvent to obtain a concrete, and the concrete is then washed with ethanol to obtain the absolute.

У парфумерії
Blackcurrant bud absolute is often used in red fruit reconstitutions. It works well with rose to bring freshness to the top and fruitiness and greenness to the heart. Its sweet, sulphurous notes soften certain spices and facilitate their use in floral reconstitutions such as violet or green gardenia. It is perfectly adapted to floral accords and can also be a very good fixative or harmoniser in chypres.
