The Brussels sprout is a member of the Gemmifera Group of cabbages (Brassica oleracea), grown for its edible buds.

The leafy green vegetables are typically 2.5–4 cm (0.98–1.6 in) in diameter and look like miniature cabbages. The Brussels sprout has long been popular in Brussels, Belgium, and may have originated and gained its name there.[1]

Forerunners to modern Brussels sprouts were likely cultivated in Ancient Rome. Brussels sprouts as they are now known were grown possibly as early as the 13th century in what is now Belgium.[2] The first written reference dates to 1587.[2] During the 16th century, they enjoyed a popularity in the southern Netherlands that eventually spread throughout the cooler parts of Northern Europe.

Brussels sprouts grow in temperature ranges of 7–24 °C (45–75 °F), with highest yields at 15–18 °C (59–64 °F).[3] Fields are ready for harvest 90 to 180 days after planting.[2] The edible sprouts grow like buds in helical patterns along the side of long, thick stalks of about 60 to 120 cm (24 to 47 in) in height, maturing over several weeks from the lower to the upper part of the stalk. Sprouts may be picked by hand into baskets, in which case several harvests are made of five to 15 sprouts at a time, or by cutting the entire stalk at once for processing, or by mechanical harvester, depending on variety.[2] Each stalk can produce 1.1 to 1.4 kg (2.4 to 3.1 lb), although the commercial yield is about 900 g (2.0 lb) per stalk.[3] Harvest season in temperate zones of the northern latitudes is September to March, making Brussels sprout a traditional winter stock vegetable. In the home garden, harvest can be delayed as quality does not suffer from freezing. Sprouts are considered to be sweetest after a frost.[4]

Brussels sprouts are a cultivar group of the same species as cabbage, in the same family as collard greens, broccoli, kale, and kohlrabi; they are cruciferous (they belong to the Brassicaceae family; old name Cruciferae). Many cultivars are available, some being purple in colour, such as 'Ruby Crunch' or 'Red Bull'.[5]


In Continental Europe, the largest producers are the Netherlands, at 82,000 metric tons, and Germany, at 10,000 tons. The United Kingdom has production comparable to that of the Netherlands, but it is not generally exported.[6]

North America

Production of Brussels sprouts in the United States began in the 18th century, when French settlers brought them to Louisiana.[3] The first plantings in California's Central Coast began in the 1920s, with significant production beginning in the 1940s. Currently, several thousand acres are planted in coastal areas of San Mateo, Santa Cruz, and Monterey counties of California, which offer an ideal combination of coastal fog and cool temperatures year-round. The harvest season lasts from June through January.[2][7]

Most American production is in California,[8] with a smaller percentage of the crop grown in Skagit Valley, Washington, where cool springs, mild summers and rich soil abounds, and to a lesser degree on Long Island, New York.[9] Total American production is approximately 32,000 tons, with a value of $27 million.[3]

About 80% to 85% of US production is for the frozen food market, with the remainder for fresh consumption.[9] Once harvested, sprouts last three to five weeks under ideal near-freezing conditions before wilting and discolouring, and about half as long at refrigerator temperature.[3] American varieties are generally 2.5–5 cm (0.98–1.97 in) in diameter.[3]

Ontario, Canada, produces about 1,000 tons per year.[10]

They are also grown in Baja California, Mexico, where the harvest season is from December through June.[7]

Nutrients, phytochemicals and research

Raw Brussels sprouts contain excellent levels of vitamin C and vitamin K, with more moderate amounts of B vitamins, such as folic acid and vitamin B6 (USDA nutrient table, right); essential minerals and dietary fibre exist in lesser amounts (table).

Brussels sprouts, as with broccoli and other brassicas, contain sulforaphane, a phytochemical under basic research for its potential anticancer properties. Although boiling reduces the level of sulforaphane, steaming and stir frying do not result in significant loss.[11]

Consuming Brussels sprouts in excess may not be suitable for patients taking anticoagulants since they contain vitamin K, a blood-clotting factor. In one such reported incident, eating too many Brussels sprouts may have countered blood-thinning therapy.[12]

Cooking and preparation

The most common method of preparing Brussels sprouts for cooking begins with cutting the buds off the stalk. Any surplus stem is cut away, and any loose surface leaves are peeled and discarded. Once cut and cleaned, the buds are typically cooked by boiling, steaming, stir frying, grilling, or roasting. To ensure even cooking throughout, buds of a similar size are usually chosen. Some cooks will make a single cut or a cross in the center of the stem to aid the penetration of heat. Brussels sprouts can be pickled as an alternative to cooking.

Overcooking will render the buds gray and soft, and they then develop a strong flavour and odour that some dislike.[8] The odour is associated with the

Common toppings or additions for Brussels sprouts include Parmesan cheese and butter, balsamic vinegar, apple cider vinegar, bacon, pistachios, pine nuts, mustard, brown sugar, and pepper. Another popular way of cooking Brussels sprouts is to sauté them. [13]
