Scent

Blackcurrant bud absolute has a well-balanced duality between distinctly sulphurous, green notes and a fruity dimension. It is also minty and rosy. At very low dosage it offers syrupy gourmand notes evoking the aromas of edible blackcurrant. It also has very particular and powerful green touches. The thiol 4-methoxy-2-methyl-2-butanethiol is described by the percepts cat and black currant.

The Full Story

The blackcurrant, Ribes nigrum, is a medium-sized shrub native to northern Europe and Asia. All parts of the plant are strongly aromatic. Its flowers are produced in racemes known as strigs, up to 8 cm long, containing 10-20 flowers each about 8 millimetres in diameter. Ribes is a genus of about 200 species of flowering plants and the only genus in the family Grossulariaceae.

Blackcurrant bud absolute is one of the few natural fruity notes in perfumery. The unopened buds of blackcurrant are distilled for their essential oil for use in perfumery. The volatile aromatic components of the plant are abundantly represented in dormant buds. Leaves contain about 25 per cent of the total amount of aromatic substances in buds. From the viewpoint of organoleptic characters, the neutral fraction of the aromatic substances is the richest and most acceptable. In food flavours, the absolute heightens the fruity and green notes of sparkling beverages and suits fruit flavours.

4-Methoxy-2-methyl-2-butanethiol is a powerful sulfur-containing aroma compound that was identified several decades ago in blackcurrant buds. It has the formula C₆H₁₄OS and a molecular weight of 134.24. A 2016 study demonstrated its occurrence in blackcurrant berries for the first time, by the analysis of seven cultivars. Its concentration in the cultivar Andega, 4.5 μg/kg, was significantly higher than in the other cultivars investigated, which ranged from 0.16 to 0.72 μg/kg.

Did You Know?

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.

Extraction & Chemistry

Extraction method

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.

In Perfumery

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.
