Blackcurrant: Difference between revisions

This article is about Ribes nigrum, a temperate climate berry bush commonly termed Blackcurrant (Black currant).

Note that Redcurrant and Whitecurrant are a different species called Ribes rubrum, discussed in a separate article (See; Currants).

Taxonomy

Family: Grossulariaceae

Genus: Ribes

Species: R. nigrum

Blackcurrant is therefore closely related to Gooseberry (R. uva-crispa). Jostaberry is a hybrid between R. nigrum, R. uva-crispa and R. divaricatum.

Common Names

• Garden black currant.^[1]
• European blackcurrant.^[2]
• Gazels / gazles.^[2]
• Quinsy berry.^[2]
• Squinancy berry.^[2]

Etymology

The word currant used to exclusively refer to the type of dried grape cultivar ("Black Corinth"). It was shortened from the phrase "raysyn of Curans" (late 14c.), from Anglo-French "reisin de Corauntz" or "raisins de Corinthe" (grapes of Corinth), referring to the Greek harbor of Corinth that was the primary source of export. Gradually, the name got corrupted into currant.^[3] In circa 1570 the word was also applied to certain berry bushes of Northern Europe, and later applied to plants with similar fruit in America and Australia.^[4]

Ribes (pronounced "RYE-bees") is Latin for "currant” (from Arabic rībās meaning "rhubarb"). Nigrum (pronounced "NIGH-grum") is Latin for "black, dark, sable, dusky."

Range

Blackcurrants are very hardy and will thrive only in cool, temperate climates.^[5] Their original range was Europe (excluding warmer mediterranean regions) and Northern and Central Asia.

Maintenance

Mulch generously each spring (ideally well-rotted manure).^[8] Use general purpose fertiliser (e.g. blood, fish and bone) in mid to late April.^[8] In early summer use nitrogen rich feed (e.g. poultry manure pellets, 2-3 handfuls per plant).^[8]

Watering

Pruning

Problems

• Birds -- consider protecting ripening fruit using nets.^[8]

• Big Bud -- caused by gall mites which occupy the buds, giving a rounded and fat appearnce of the buds (instead of long and slim). Occurs in spring before bud burst. Check plants in spring and cut off any affected buds and then burn the buds.^[8]

• Reversion -- disease also spread by gall mites. Causes unnatural foliage and reduced fruit crop.^[8]

Harvest

Fruit are ripe when they have swelled to maximum size and have a shiny, jet black appearance.^[8] The longer the fruit are left on the plant the sweeter they get.^[8] Whole trusses (trigs) or blackcurrants are removed from the branches to harvest.^[8] Picking individual fruits off the trusses can be tedious.^[8] One method is to hold the thick end of the stalk and pull the truss through the prongs of a dining fork.^[8]

Uses

• Fruits can be eaten raw.
• Juiced. One blackcurrant juice recepie is to place trusses of blackcurrants into a pan with a little watter. When softened, mash and let juice drip through a mesh bag. Add sugar while still warm (or reduce the sugar by using sweet cicely leaves and stalks, e.g. 3-4 leaves per 450g of blackcurrants, removing leaves after cooking). Dilute with water to drink as a cordial, or add 1 spoonful to a glass of white or sparkling wine as a "Kir". The undiluted juice can also be used as a base for sauces. Keeps for 1 week if refidgerated, or frozen (e.g. in ice cube trays).^[8]
• Cooked to make sauces (very good with duck), crumbles.
• Alcoholic drinks, see: Household Cyclopedia, Wines and Ciders (1881)
• Jam.
• Jelly.
