Portobello Mushroom
The portobello is the large, mature, brown-capped form of the common cultivated mushroom, the same species sold younger as cremini or white button mushrooms. It is mainly a culinary ingredient. In drinks it plays a minor, mostly modern role, appearing in savory broths, umami infusions, and experimental non-alcoholic preparations rather than in any established traditional beverage.
How portobello mushroom is prepared
It is used occasionally as a base for sipping broths and consommés, as an infusion or reduction that adds savory depth to tomato- or vegetable-based mocktails, and as an earthy accent in experimental shrubs and savory syrups. It is not psychoactive and is unrelated to the 'mushroom' culture used to brew kombucha.

One Species, Many Names
The portobello is not a distinct kind of mushroom. It is Agaricus bisporus allowed to mature until its cap opens wide, typically to around 10 to 15 centimeters, and its gills darken to deep brown. The same fungus, harvested young, is sold as the white button mushroom, or as cremini, chestnut, or baby bella when it is young and brown. The wild species grows in rich soil, compost, and manure across Eurasia and North America. Today it is farmed in more than seventy countries, making it one of the most widely eaten mushrooms on earth. Its main identity has always been as a food. Any role in beverages builds on its strong savory flavor rather than on a drinking tradition of its own.[1]
European Cultivation and the Broth Tradition
Systematic cultivation of this mushroom began in France. Growers there first transplanted mycelium from productive fields into beds of composted manure, and by the late 19th century pure-culture spawn made production reliable. The mushroom spread through European and later American kitchens as an ingredient for sauces, soups, and stocks. This is where its nearest approach to a 'drink' lies: clear mushroom broths and consommés, sometimes served in cups as a warming starter. The brown, fully opened form that would later be called portobello was long regarded as less marketable than tight young caps. It became a prized product in its own right only in the late 20th century, and the origin of its commercial name remains uncertain.[1]
East Asian Mushroom Teas: A Tradition Without the Portobello
The strongest living tradition of mushrooms as beverages belongs to East Asia, and it uses different species. In Korea, infusions grouped under the name beoseot-cha are brewed from mushrooms such as shiitake, oyster mushroom, scaly hedgehog, black hoof mushroom, and lingzhi. These teas are typically prepared from dried fungi and valued for flavor or perceived wellness benefits. The portobello has no place in this repertoire. Modern cooks who make a simple infusion of dried, sliced portobello in hot water are, however, borrowing the basic technique of these teas. They apply it to a Western mushroom to produce an earthy, savory cup closer to a light broth than to a herbal tea.[2]
Kombucha and the 'Tea Mushroom' Misnomer
Because kombucha's starter culture is often called a 'mushroom' or 'tea fungus', readers sometimes assume that a true mushroom goes into the drink. In fact, kombucha is sweetened tea fermented by a gelatinous mat of acetic acid bacteria and yeasts. The drink is believed to come from northeastern China and spread through Russia and Europe before becoming a global low-alcohol staple in the 21st century. No portobello or other mushroom fruiting body is involved. The overlap is purely one of name, and it is worth stating clearly in any account of mushrooms in drinks.[3]
Fungal Fermentation in Japanese Rice Drinks
Japan offers another instructive contrast. Amazake, a sweet, low- or non-alcoholic rice drink, and sake, its alcoholic relative, both depend on koji, the mold Aspergillus oryzae. Koji breaks down rice starch into sugars. Here a fungus is central to the beverage, but as a microscopic mold acting as a fermentation agent, not as an edible mushroom used for flavor. The portobello plays no part in these traditions. Contemporary bartenders and chefs sometimes pair the two worlds in savory, umami-driven menus, setting the mushroom's earthiness alongside the gentle sweetness of rice ferments.[4]
Distinct from Psychoactive Mushroom Brews
Another source of confusion is the 'magic mushroom' tea made from psilocybin-containing species, mostly of the genus Psilocybe. These fungi were used ritually in pre-Columbian Mexico and attracted Western attention in the mid-20th century. They are sometimes steeped in hot water or soaked in lemon juice before being consumed. The portobello belongs to an entirely different genus and contains no psilocybin or related compounds. Any drink made from it is purely culinary, with no psychoactive effect.[5]
