Ginger beer (brewed, ginger-beer plant or ginger bug)ginger beer

Traditional ginger beer is sugar water with ginger, fermented by the ginger-beer plant, a jelly-like clump of a yeast and a bacterium, or by a home-grown ginger bug. After a day or two in an open pot it is bottled and corked, and gas builds up until it is fizzy.

At a glance

Traditional ginger beer is sugar water with ginger, fermented by the ginger-beer plant, a jelly-like clump of a yeast and a bacterium, or by a home-grown ginger bug. After a day or two in an open pot it is bottled and corked, and gas builds up until it is fizzy. Made in 7 steps over 7 days – 9 days. The longest step, revive or start the culture, takes 4 days (de Oliveira L.I.G. et al. 2024). Saccharomyces florentinus and Lentilactobacillus hilgardii do most of the fermenting.

What makes this one different

Ginger ale is carbonated with pressurised gas, but brewed ginger beer gets its fizz from live fermentation in the bottle. The ginger-beer plant is one symbiotic clump. The bacterium's thick slime sheaths hold the yeast cells, and Ward rebuilt the plant by mixing the two pure cultures.

Variants

  • Ginger-beer plant (GBP)Jelly-like clumps passed on between households and reused by pouring fresh sugar water on the lees.
  • Ginger bugGinger, sugar and water fed until it bubbles; in one study 96 h of activation and 14 days of fermentation gave the best ginger beer.
  • Botswana ginger beerHome brew; one sample from Gantsi had pH 2.89 and 3.99 % v/v ethanol.

Made the ginger beer way

Bees wine used the same kind of grains as the ginger beer plant, but grown in brown sugar and treacle rather than a ginger and sugar brew, and the grains were kept going by topping up the jar. Mix (1891) named the American grains "American kephir" because they resemble kefir grains, with distinct differences.

Safety

Pressure is the main hazard. Ward warned that corked bottles can burst within a few days, and WSU's fermentation programme warns that a closed container that over-ferments can build pressure until it explodes. Brewed ginger beer is not alcohol-free; a Botswana home brew had 3.99 % ethanol. For the related kombucha, the US TTB treats a drink that reaches 0.5 % alcohol by volume at any time, including after bottling, as an alcohol beverage.

History and sources

Every number is labelled with how it is known. How this atlas is made

Harry Marshall Ward studied ginger-beer plant samples from 1887, sent from Kew, Oxford and elsewhere in Britain and from America. He found it in home ginger-beer making across the British Isles, where the drink was sold in brown stoneware bottles with tied corks. Wikipedia says brewed ginger beer originated in Yorkshire, England, in the mid-18th century and appeared in Canada and the United States around 1790.
