Cassis bud absolute

Other comments :

The price of blackcurrant buds absolute has declined thanks to the arrival of new mechanical cultivation devices. Its price was justified by its harvesting method. Despite its very good performance, it took about 200 hours of manual labor to obtain 1kg of this dark green dough with its characteristic smell.

For example, Ribes bracteosum, or Californian blackcurrant; Ribes californicum, or hillside gooseberry, also native to California; Ribes amarum, or bitter gooseberry; Ribes triste, or northern redcurrant, native to Canada; Ribes rubrum, or red currant, corresponding to common gooseberry.

Extraction process :

Blackcurrant, or black currant (Ribes nigrum), is a shrub with very fragrant leaves, although only the buds are used in perfumery. The buds are grown using a harvester that cuts the blackcurrant wood, disbudding in January. The use of a harvester gives 100 kg of buds in one day, against 100 g of bud per hour by hand, as it was the case until the 90s. The buds are separated from the chips of wood in the factory by a suitable filter.
The buds are treated fresh at the plant in an extraction tank. A first extraction is made using hexane, incorporated and heated in the tank. After removal of the buds and evaporation of the hexane, the concrete is collected. The absolute is obtained by diluting the concrete in alcohol, then passing the temperature of the medium from about 60 ° C to 0 ° C. The buds are exctracted with a volatile solvent with a yield of 4% for the concrete, then 80% for the absolute made from the concrete. The blackcurrant bud absolute can be distilled to be bleached, without a great olfactory deterioration.
