Redcurrants are the small, translucent, tart red berries of Ribes rubrum, borne in clusters on a common stalk.
Sharp acidity dominates, backed by only faint sweetness and a mild, restrained aroma.
Reached for as a visual finish, a small strig is draped over the rim or floated on the surface to add a bright, jewel-like cluster of red. The fruit is used fresh and left on its intact stem rather than picked loose.
Another small, bright-red berry cluster can stand in, since the role here is visual — any tartness it lacks is trivially rebalanced with other acids in the drink.
Blackcurrant
Redcurrants are translucent red, sharply tart and mild in aroma; blackcurrants are dark purple-black with a much more intense, musky aroma and richer flavour. They are distinct Ribes species.
Ribes rubrum is a deciduous shrub in the family Grossulariaceae, native to western and central Europe. The berries hang in pendulous clusters called strigs, each attached to a common stem, so the fruit is commonly presented and served on the stem.
A soft, delicate berry that bruises and deteriorates quickly; refrigerate and use fresh.
