'''Cabbage''', comprising several [[cultivar]]s of ''[[Brassica oleracea]]'', is a leafy green, red (purple), or white (pale green) [[biennial plant]] grown as an [[Annual plant|annual]] vegetable crop for its dense-leaved heads. It is descended from the wild cabbage ([[Brassica oleracea|''B.&nbsp;oleracea'' var. ''oleracea'']]), and belongs to the "[[cole crops]]" or brassicas, meaning it is closely related to [[broccoli]] and [[cauliflower]] (var. ''botrytis''); [[Brussels sprouts]] (var. ''gemmifera''); and [[Savoy cabbage]] (var. ''sabauda'').

A cabbage generally weighs between {{convert|500|and|1000|g|lbs|sigfig=1}}. Smooth-leafed, firm-headed green cabbages are the most common, with smooth-leafed purple cabbages and crinkle-leafed savoy cabbages of both colours being rarer. Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large. {{As of|2012}}, the heaviest cabbage was {{convert|62.71|kg|lboz|frac=2}}. <!-- Some records are discussed at the end of the history section. --> Cabbage heads are generally picked during the first year of the plant's [[Biological life cycle|life cycle]], but plants intended for seed are allowed to grow a second year and must be kept separate from other [[cole crops]] to prevent [[cross-pollination]]. Cabbage is prone to several [[micronutrient deficiency|nutrient deficiencies]], as well as to multiple [[Pest (agriculture)|pests]], and bacterial and fungal diseases.

Cabbage was most likely [[domestication|domesticated]] somewhere in [[Europe]] in [[ancient history]] before 1000 BC.

They can be prepared many different ways for eating; they can be [[pickling|pickled]], [[fermented]] (for dishes such as [[sauerkraut]], [[kimchi]]), [[steaming|steamed]], [[stewing|stewed]], [[roasting|roasted]], [[Sautéing|sautéed]], [[braising|braised]], or eaten [[Raw food|raw]]. Raw cabbage is a rich source of [[vitamin K]], [[vitamin C]], and [[dietary fiber]]. World production of cabbage and other [[brassica]]s in 2020 was 71 million [[tonne]]s, led by [[China]] with 48% of the total.

[[File:Brassica oleracea Helgoland1.jpg|thumb|right|upright|The cabbage [[inflorescence]], which appears in the plant's second year of growth, features white or yellow flowers, each with four perpendicularly arranged petals.]]

Cabbage [[seedling]]s have a thin [[taproot]] and cordate (heart-shaped) [[cotyledon]]s. The first leaves produced are ovate (egg-shaped) with a lobed [[petiole (botany)|petiole]]. Plants are {{convert|40|–|60|cm|abbr=off|frac=2}} tall in their first year at the mature vegetative stage, and {{convert|1.5-2|m|ft|abbr=off|frac=2}} tall when flowering in the second year.<ref name="Dixon p19">[[Cabbage#Dixon|Dixon]], p. 19</ref> Heads average between {{convert|1|and|8|lbs|sigfig=1|abbr=off|order=flip}}, with fast-growing, earlier-maturing varieties producing smaller heads.<ref name="UI">{{cite web |title=Cabbage |url=http://urbanext.illinois.edu/veggies/cabbage.cfm |access-date=2012-08-10 |publisher=University of Illinois Extension}}</ref> Most cabbages have thick, alternating leaves, with margins that range from wavy or lobed to highly dissected; some varieties have a [[epicuticular wax|waxy bloom]] on the leaves. Plants have root systems that are fibrous and shallow.<ref name="Katz279" /> About 90% of the root mass is in the upper {{convert|20|–|30|cm|in|0|abbr=on}} of soil; some [[lateral root]]s can penetrate up to {{convert|2|m|ft|abbr=on|frac=2}} deep.<ref name="Dixon p19" />

The [[inflorescence]] is an unbranched and [[indeterminate growth|indeterminate]] terminal [[raceme]] measuring {{convert|50|–|100|cm|in|-1|abbr=on}} tall,<ref name="Dixon p19" /> with flowers that are yellow or white. Each flower has four [[petal]]s set in a perpendicular pattern, as well as four [[sepal]]s, six [[stamen]]s, and a [[superior ovary]] that is two-celled and contains a single [[stigma (botany)|stigma]] and [[style (botany)|style]]. Two of the six stamens have shorter filaments. The fruit is a [[silique]] that opens at maturity through [[Dehiscence (botany)|dehiscence]] to reveal brown or black seeds that are small and round in shape. [[Self-pollination]] is impossible, and plants are [[cross-pollinated]] by insects.<ref name="Katz279" /> The initial leaves form a rosette shape comprising 7 to 15 leaves, each measuring {{convert|25|–|35|cm|in|0|abbr=on}} by {{convert|20|–|30|cm|in|0|abbr=on}};<ref name="Dixon p19" /> after this, leaves with shorter petioles develop and heads form through the leaves cupping inward.<ref name="WI1" />

Many shapes, colors and leaf textures are found in various cultivated varieties of cabbage. Leaf types are generally divided between crinkled-leaf, loose-head savoys and smooth-leaf firm-head cabbages, while the color spectrum includes white and a range of greens and purples. Oblate, round and pointed shapes are found.<ref name="Katz280">[[Cabbage#Katz|Katz and Weaver]], p. 280</ref>

=== Etymology ===
The original family name of brassicas was ''Cruciferae'', which derived from the flower petal pattern thought by medieval Europeans to resemble a [[crucifix]].<ref name="Katz279">[[#Katz|Katz and Weaver]], p. 279</ref> The word ''brassica'' derives from ''bresic'', a [[Celtic languages|Celtic]] word for cabbage.<ref name="Texas">{{cite web|url=http://aggie-horticulture.tamu.edu/archives/parsons/publications/vegetabletravelers/cabbage.html|title=Of Cabbages and Celts|access-date=2013-10-19|publisher=Texas A&M University|work=Aggie Horticulture}}</ref> The varietal [[botanical name|epithet]] ''capitata'' is derived from the [[Latin]] word for 'having a head'.<ref name="Small 2009">{{cite book |author=Small, Ernst |url=https://books.google.com/books?id=nyWY_YkV7qAC&pg=PA127 |title=Top 100 Food Plants |publisher=NRC Research Press |year=2009 |isbn=978-0-660-19858-3 |page=127}}</ref>

Many European and Asiatic names for cabbage are derived from the [[Proto-Slavic borrowings|Celto-Slavic]] root ''cap'' or ''kap'', meaning "head".<ref name="Sturtevant 1919" /> The [[late Middle English]] word ''cabbage'' derives from the word ''caboche'' ("head"), from the [[Picard language|Picard dialect]] of [[Old French]]. This in turn is a variant of the Old French ''caboce''.<ref name="Oxford">{{cite book|page=[https://archive.org/details/oxforddictionary0000unse_x2z7/page/76 76]|title=The Oxford Dictionary of Word Histories|editor=Chantrell, Glynnis|publisher=Oxford University Press|year=2002|isbn=978-0-19-863121-7|url=https://archive.org/details/oxforddictionary0000unse_x2z7/page/76}}</ref>

=== History ===
Although cabbage has an extensive history,<ref name="briefhistoricalsketch"/> it is difficult to trace its exact origins owing to the many varieties of leafy greens classified as "brassicas".<ref name=Ingram/> A possible wild ancestor of cabbage, ''[[Brassica oleracea]]'', originally found in Britain and continental Europe, is tolerant of salt but not encroachment by other plants and consequently inhabits rocky cliffs in cool damp coastal habitats,<ref>[[#Dixon|Dixon]], p. 2</ref> retaining water and nutrients in its slightly thickened, turgid leaves. However, genetic analysis is consistent with [[feral]] origin of this population, deriving from plants escaped from field and gardens.<ref>{{Cite journal|doi = 10.1007/s10722-020-00945-0|title = Survey and genetic diversity of wild ''Brassica oleracea'' L.

Cabbage was probably domesticated later in history than [[Near East]]ern crops such as [[lentil]]s and [[wheat|summer wheat]]. Because of the wide range of crops developed from the wild ''B.&nbsp;oleracea'', multiple broadly contemporaneous domestications of cabbage may have occurred throughout Europe. Nonheading cabbages and kale were probably the first to be domesticated, before 1000 BC,<ref name=Katz284>[[#Katz|Katz and Weaver]], p. 284</ref> perhaps by the [[Celts]] of central and western Europe,<ref name=Texas/> although recent linguistic and genetic evidence enforces a Mediterranean origin of cultivated brassicas.<ref>{{Cite journal|last=Maggioni|first=Lorenzo|date=2015|title=Domestication of ''Brassica oleracea'' L.|url=https://pub.epsilon.slu.se/12424/1/maggioni_l_150720.pdf|journal=Acta Universitatis Agriculturae Sueciae|volume=Doctoral Thesis no. 2015:74}}</ref>

While unidentified brassicas were part of the highly conservative unchanging [[Mesopotamia]]n garden repertory,<ref>"Cabbage plants" are mentioned in Oppenheim, A. Leo (1977) ''Ancient Mesopotamia: Portrait of a Dead Civilization''.

Bowman, ''Egypt After the Pharaohs'', p 151.</ref>

[[Chrysippus of Cnidos]] wrote a treatise on cabbage, which Pliny knew,<ref>[[Pliny's Natural History]], 20. 78-83.</ref> but it has not survived. The Greeks were convinced that cabbages and [[grapevine]]s were inimical, and that cabbage planted too near the vine would impart its unwelcome odor to the grapes; this Mediterranean sense of antipathy survives today.<ref name="Toussaint">[[#Toussaint-Samat|Toussaint-Samat]], p. 622.</ref>

''Brassica'' was considered by some Romans a table luxury,<ref name="Pompeii">{{cite book |title=The Natural History of Pompeii |publisher=Cambridge University Press |year=2002 |page=94 |isbn=978-0-521-80054-9}}</ref> although [[Lucullus]] considered it unfit for the senatorial table.<ref>[[#Toussaint-Samat|Toussaint-Samat]], p. 623.</ref> The more traditionalist [[Cato the Elder]], espousing a simple Republican life, ate his cabbage cooked or raw and dressed with vinegar; he said it surpassed all other vegetables, and approvingly distinguished three varieties; he also gave directions for its medicinal use, which extended to the cabbage-eater's urine, in which infants might be rinsed.<ref>Cato, ''De agricultura'', CLVI, CLVII; the passages are paraphrased by Pliny the Elder.</ref> [[Pliny the Elder]] listed seven varieties, including [[Pompeii]] cabbage, [[Cumae]] cabbage and [[Sabellians|Sabellian]] cabbage.<ref name="encyclopedia"/> 

According to Pliny, the Pompeii cabbage, which could not stand cold, is "taller, and has a thick stock near the root, but grows thicker between the leaves, these being scantier and narrower, but their tenderness is a valuable quality".<ref name="Pompeii"/> The Pompeii cabbage was also mentioned by [[Columella]] in [[Columella#De Re Rustica|''De Re Rustica'']].<ref name="Pompeii"/> [[Apicius]] gives several recipes for ''cauliculi'', tender cabbage shoots. The Greeks and Romans claimed medicinal usages for their cabbage varieties that included relief from [[gout]], headaches and the symptoms of [[poisonous mushroom]] ingestion.<ref name=UCD>{{cite web|url=http://aic.ucdavis.edu/profiles/Cabbage_2006.pdf|publisher=University of California – Davis|access-date=2012-08-21|title=Commodity Profile: Cabbage|author1=Boriss, Hayley|author2=Kreith, Marcia|date=February 2006|archive-url=https://web.archive.org/web/20121207142003/http://aic.ucdavis.edu/profiles/Cabbage_2006.pdf|archive-date=2012-12-07|url-status=dead}}</ref>  

The antipathy towards the vine made it seem that eating cabbage would enable one to avoid drunkenness.<ref name="Toussaint"/> Cabbage continued to figure in the ''[[materia medica]]'' of antiquity as well as at table: in the first century AD [[Pedanius Dioscorides|Dioscorides]] mentions two kinds of coleworts with medical uses, the cultivated and the wild,<ref name="Sturtevant 1919">{{cite book |author=Sturtevant, Edward Lewis |author-link=Edward Lewis Sturtevant |title=Sturtevant's Notes on Edible Plants |year=1919 |publisher=J.B.&nbsp;Lyon |pages=115, 117 |url=https://www.biodiversitylibrary.org/page/20118475|isbn=9780486204598 }}</ref> and his opinions continued to be paraphrased in [[herbals]] right through the 17th century.

At the end of Antiquity cabbage is mentioned in ''De observatione ciborum'' ("On the Observance of Foods") by [[Anthimus (physician)|Anthimus]], a Greek doctor at the court of [[Theodoric the Great]]. Cabbage appears among vegetables directed to be cultivated in the ''[[Capitulare de villis]]'', composed in 771–800 AD, that guided the governance of the royal estates of [[Charlemagne]].

In Britain, the Anglo-Saxons cultivated ''cawel''.<ref>Bosworth, Joseph. ed. ''An Anglo-Saxon Dictionary'', ''s.v.'' "cawel" gives parallels: Scottish ''kail, kale''; Frisian ''koal, koel''; Dutch ''kool'' (fem.); German ''kohl'' (masc.), etc. but also Welsh ''cawl''; Cornish ''caul'' (masc.); etc.  Compare Latin ''caulis''.</ref> When round-headed cabbages appeared in 14th-century England they were called ''cabaches'' and ''caboches'', words drawn from [[Old French]] and applied at first to refer to the ball of unopened leaves,<ref>''[[OED]]'': "cabbage".</ref> the contemporaneous recipe that commences "Take cabbages and quarter them, and seethe them in good broth",<ref>Forgeng, Jeffrey L. and McLean, Will (2009) ''Daily Life in Chaucer's England''.

[[Jacques Cartier]] first brought cabbage to the Americas in 1541–42, and it was probably planted by the early English colonists, despite the lack of written evidence of its existence there until the mid-17th century. By the 18th century, it was commonly planted by both colonists and native [[Native Americans in the United States|American Indians]].<ref name=Texas/> Cabbage seeds traveled to Australia in 1788 with the [[First Fleet]], and were planted the same year on [[Norfolk Island]]. It became a favorite vegetable of Australians by the 1830s and was frequently seen at the [[Sydney Markets]].<ref name=Sydney>{{cite web|url=http://www.freshforkids.com.au/veg_pages/cabbage/cabbage.html|title=Cabbage|publisher=Sydney Markets, Ltd|access-date=2012-08-10|url-status=dead|archive-url=https://web.archive.org/web/20120808031331/http://www.freshforkids.com.au/veg_pages/cabbage/cabbage.html|archive-date=2012-08-08}}</ref> In [[Brno]], Czech Republic there is an open-air market named after cabbage which has been in operation since 1325, the [[Zelný trh]].

=== Modern cultivation ===
[[File:Dojranski zelki.jpg|thumb|A cabbage field]]
Cabbage is generally grown for its densely leaved heads, produced during the first year of its biennial cycle. Plants perform best when grown in well-drained soil in a location that receives full sun. Different varieties prefer different soil types, ranging from lighter sand to heavier clay, but all prefer fertile ground with a [[Soil pH|pH]] between 6.0 and 6.8.<ref name=Brad56/> For optimal growth, there must be adequate levels of [[nitrogen]] in the soil, especially during the early head formation stage, and sufficient [[phosphorus]] and [[potassium]] during the early stages of expansion of the outer leaves.<ref name="Wien and Wurr 533">[[#Wurr|Wien and Wurr]], p. 533</ref> 

Temperatures between {{convert|4|and|24|C|F}} prompt the best growth, and extended periods of higher or lower temperatures may result in premature [[bolting (horticulture)|bolting]] (flowering).<ref name=Brad56>[[#Bradley|Bradley et al.]], pp. 56–57</ref> Flowering induced by periods of low temperatures (a process called [[vernalization]]) only occurs if the plant is past the juvenile period. The transition from a juvenile to adult state happens when the stem diameter is about {{convert|6|mm|in|frac=16|abbr=on}}. Vernalization allows the plant to grow to an adequate size before flowering. In certain climates, cabbage can be planted at the beginning of the cold period and survive until a later warm period without being induced to flower, a practice that was common in the eastern US.<ref>[[#Wurr|Wien and Wurr]], pp. 512–515</ref>

[[File:Cabbages Green and Purple 2120px.jpg|thumb|right|upright|Green and purple cabbages]]
Plants are generally started in protected locations early in the growing season before being [[transplanting|transplanted]] outside, although some are seeded directly into the ground from which they will be harvested.<ref name=UI/> Seedlings typically emerge in about 4–6 days from seeds planted {{convert|1/2|in|mm|abbr=on|order=flip}} deep at a soil temperature between {{convert|20|and|30|C|F}}.<ref>[[#Maynard|Maynard and Hochmuth]], p. 111</ref> Growers normally place plants {{convert|12|to|24|in|cm|order=flip|abbr=on}} apart.<ref name=UI/> Closer spacing reduces the resources available to each plant (especially the amount of light) and increases the time taken to reach maturity.<ref>[[#Wurr|Wien and Wurr]], p. 534</ref> 

Some varieties of cabbage have been developed for ornamental use; these are generally called "flowering cabbage". They do not produce heads and feature purple or green outer leaves surrounding an inner grouping of smaller leaves in white, red, or pink.<ref name=UI/> Early varieties of cabbage take about 70 days from planting to reach maturity, while late varieties take about 120 days.<ref>[[#Maynard|Maynard and Hochmuth]], p. 415</ref> 

Cabbages are mature when they are firm and solid to the touch. They are harvested by cutting the stalk just below the bottom leaves with a blade. The outer leaves are trimmed, and any diseased, damaged, or necrotic leaves are removed.<ref>{{cite book |author=Thompson, A. Keith |title=Fruit and Vegetables: Harvesting, Handling and Storage |year=2003 |edition=2nd |publisher=Blackwell Publishing |page=178 |isbn=978-1-4051-0619-1}}</ref> Delays in harvest can result in the head splitting as a result of expansion of the inner leaves and continued stem growth.<ref>[[#Wurr|Wien and Wurr]], p. 524</ref>

When being grown for seed, cabbages must be isolated from other ''B.&nbsp;oleracea'' subspecies, including the wild varieties, by {{convert|1/2|to|1|mi|km|1|order=flip|abbr=on}} to prevent cross-pollination. Other ''Brassica'' [[species]], such as ''[[Brassica rapa|B.&nbsp;rapa]]'', ''[[Brassica juncea|B.&nbsp;juncea]]'', ''[[Brassica nigra|B.&nbsp;nigra]]'', ''[[Brassica napus|B.&nbsp;napus]]'' and ''[[Raphanus sativus]]'', do not readily cross-pollinate.<ref>[[#Katz|Katz and Weaver]], p. 282</ref>

===Cultivars===
[[File:Cabbage.jpg|thumb|White cabbage]]
There are several [[cultivar group]]s of cabbage, each including many cultivars:
* [[Savoy cabbage|Savoy]]&nbsp;– Characterized by crimped or curly leaves, mild flavor and tender texture<ref name=Ingram/>
* [[Spring greens (Brassica oleracea)]]&nbsp;– Loose-headed, commonly sliced and steamed<ref name=Ingram/>
* Green&nbsp;– Light to dark green, slightly pointed heads.<ref name=Ingram/>
* [[Red cabbage|Red]]&nbsp;– Smooth red leaves, often used for pickling or stewing<ref name=Ingram/>
* White, also called Dutch&nbsp;– Smooth, pale green leaves<ref name=Ingram/>

Some sources only delineate three cultivars: savoy, red and white, with spring greens and green cabbage being subsumed under the last.<ref>[[#Ordas|Ordas and Cartea]], p. 124</ref>

===Cultivation problems===
Due to its high level of nutrient requirements, cabbage is prone to [[micronutrient deficiency|nutrient deficiencies]], including [[Boron deficiency (plant disorder)|boron]], [[Calcium deficiency (plant disorder)|calcium]], [[Phosphorus deficiency|phosphorus]] and [[Potassium deficiency (plants)|potassium]].<ref name=Brad56/> There are several physiological disorders that can affect the postharvest appearance of cabbage. Internal tip burn occurs when the margins of inside leaves turn brown, but the outer leaves look normal. Necrotic spot is where there are oval sunken spots a few millimeters across that are often grouped around the midrib. In pepper spot, tiny black spots occur on the areas between the veins, which can increase during storage.<ref>{{cite web |title=Nonpathogenic Disorders of Cabbage |url=http://vegetablemdonline.ppath.cornell.edu/factsheets/Crucifers_Nonpathogenic.htm |author1=Becker, Robert F.  |author2=Bjorkmann, Thomas |publisher=Cornell University: Department of Plant Pathology |work=Vegetable MD Online |access-date=2013-08-30}}</ref>

Fungal diseases include [[Rhizoctonia solani|wirestem]], which causes weak or dying transplants; [[Fusarium|''Fusarium'' yellows]], which result in stunted and twisted plants with yellow leaves; and [[Blackleg (Brassica)|blackleg]] (see ''[[Leptosphaeria maculans]]''), which leads to sunken areas on stems and gray-brown spotted leaves.<ref name=Brad57/> The fungi ''[[Alternaria brassicae]]'' and ''[[Alternaria brassicicola|A.&nbsp;brassicicola]]'' cause dark leaf spots in affected plants. They are both seedborne and airborne, and typically propagate from spores in infected plant debris left on the soil surface for up to twelve weeks after harvest. ''[[Rhizoctonia solani]]'' causes the post-emergence disease wirestem, resulting in killed seedlings ("damping-off"), root rot or stunted growth and smaller heads.<ref name="Keinath2007">{{cite book |author1=Keinath, Anthony P. |author2=Cubeta, Marc A. |author3=Langston Jr., David B. |chapter=Cabbage diseases: Ecology and control |title=Encyclopedia of Pest Management |volume=2 |year=2007 |editor-last=Pimentel, David |publisher=CRC Press |pages=56–59 |isbn=978-1-4200-5361-6}}</ref>

[[File:Groene savooiekool schade van kooluil (Mamestra brassicae damage).jpg|thumb|right|[[Cabbage moth]] damage to a savoy cabbage]]

One of the most common bacterial diseases to affect cabbage is [[black rot]], caused by ''[[Xanthomonas campestris]]'', which causes [[chlorosis|chlorotic]] and [[necrosis|necrotic]] lesions that start at the leaf margins, and [[wilting]] of plants. [[Clubroot]], caused by the soilborne [[slime mold]]-like organism ''Plasmodiophora brassicae'', results in swollen, club-like roots. [[Downy mildew]], a parasitic disease caused by the [[oomycete]] ''[[Peronospora parasitica]]'',<ref name="Keinath2007"/> produces pale leaves with white, brownish or olive [[mildew]] on the lower leaf surfaces; this is often confused with the fungal disease [[powdery mildew]].<ref name=Brad57/>

Pests include [[root-knot nematode]]s and [[Delia radicum|cabbage maggot]]s, which produce stunted and wilted plants with yellow leaves; [[aphid]]s, which induce stunted plants with curled and yellow leaves; [[harlequin cabbage bug]]s, which cause white and yellow leaves; [[thrip]]s, which lead to leaves with white-bronze spots; [[striped flea beetle]]s, which riddle leaves with small holes; and [[caterpillar]]s, which leave behind large, ragged holes in leaves.<ref name=Brad57>[[#Bradley|Bradley et al.]], pp. 57–59</ref> The caterpillar stage of the "small cabbage white butterfly" (''[[Pieris rapae]]''), commonly known in the United States as the "imported cabbage worm", is a major cabbage pest in most countries.<ref name="Finch2007"/>

The large white butterfly (''[[Pieris brassicae]]'') is prevalent in eastern European countries. The diamondback moth (''[[Plutella xylostella]]'') and the cabbage moth (''[[Mamestra brassicae]]'') thrive in the higher summer temperatures of continental Europe, where they cause considerable damage to cabbage crops.<ref name="Finch2007"/> The cabbage looper (''[[Cabbage looper|Trichoplusia ni]]'') is infamous in North America for its voracious appetite and for producing frass that contaminates plants.<ref>Turini TA, Daugovish O, Koike ST, Natwick ET, Ploeg A, Dara SK, Fennimore SA, Joseph S, LeStrange M, Smith R, Subbarao KV, Westerdahl BB.

Planting near other members of the cabbage family, or where these plants have been placed in previous years, can prompt the spread of pests and disease.<ref name=Brad56/> Excessive water and excessive heat can also cause cultivation problems.<ref name=Brad57/>

Factors that contribute to reduced head weight include: growth in the compacted soils that result from [[no-till farming]] practices, drought, [[waterlogging (agriculture)|waterlogging]], insect and disease incidence, and shading and nutrient stress caused by weeds.<ref name="Wien and Wurr 533"/>

{{Cookbook}}{{see also|List of cabbage dishes}}
The characteristic flavor of cabbage is caused by [[glucosinolate]]s, a class of [[sulfur]]-containing [[glucoside]]s. Although found throughout the plant, these compounds are concentrated in the highest quantities in the seeds; lesser quantities are found in young vegetative tissue, and they decrease as the tissue ages.<ref>[[Cabbage#Katz|Katz and Weaver]], pp. 282–283</ref> Cooked cabbage is often criticized for its pungent, unpleasant odor and taste.

=== Nutrition ===
Raw cabbage is 92% water, 6% [[carbohydrate]]s, 1% [[protein]], and contains negligible [[fat]]. In a 100-gram reference amount, raw cabbage is a rich source of [[vitamin C]] and [[vitamin K]], containing 44% and 72%, respectively, of the [[Daily Value]] (DV).<ref name="USDA_database">{{cite web |date=1 April 2019 |title=USDA database table for raw cabbage per 100 g |url=https://fdc.nal.usda.gov/fdc-app.html#/food-details/169975/nutrients |access-date=5 January 2020 |publisher=US Department of Agriculture, National Nutrient Database for Standard Reference, version SR-27}}</ref> Cabbage is also a moderate source (10–19% DV) of [[vitamin B6]] and [[folate]], with no other nutrients having significant content per 100-gram serving.

=== Local market and storage ===
Cabbages sold for market are generally smaller, and different varieties are used for those sold immediately upon harvest and those stored before sale. Those used for processing, especially sauerkraut, are larger and have a lower percentage of water.<ref name=Katz280/> Both hand and mechanical harvesting are used, and hand-harvesting is generally used for cabbages destined for market sales. In commercial-scale operations, hand-harvested cabbages are trimmed, sorted, and packed directly in the field to increase efficiency.<ref name="Katz&Weaver">[[#Katz|Katz and Weaver]], p. 285</ref>

[[Vacuum cooling]] rapidly refrigerates the vegetable, allowing for earlier shipping and a fresher product. Cabbage can be stored the longest at {{convert|-1|to|2|C|F}} with a humidity of 90–100%; these conditions will result in up to six months of longevity. When stored under less ideal conditions, cabbage can still last up to four months.<ref name="Katz&Weaver"/>
