How is ginger beer soda made?

Quick answer

Ginger beer is made from ginger, sugar and water. Traditional versions are fermented with a ginger bug, a jar of wild yeast and bacteria grown on ginger and sugar, which makes natural fizz. Many bottles and cans sold today are not brewed at all: they mix ginger flavoring or syrup with water and add carbon dioxide under pressure.

How is ginger beer made?

There are two main routes. The traditional route ferments the drink. The industrial route flavors water and adds gas. Which one you have depends on the maker, so check the label or the maker’s website.

The traditional method: ginger bug

  1. Put chopped ginger and sugar in a jar with water and cover it.
  2. Feed it with a little more ginger and sugar each day. One guide suggests about a quarter cup of each daily.
  3. After a few days the mix turns cloudy, bubbles and smells yeasty. That is the bug, a starter full of wild yeast and bacteria.
  4. The bug is added to a sweetened, strained ginger tea, bottled and left to build natural carbonation.

Tips from home brewers: use filtered water, because chlorine can slow the yeast, and fresh organic ginger, because some conventional ginger is irradiated, which can hurt the culture.

The commercial method

Many commercial ginger beers are made with water, ginger extract or syrup, sweetener and acid, then carbonated with pressurized carbon dioxide. Alcohol levels differ by maker and country, so read the label if you need to avoid alcohol.

Ginger beer vs ginger ale

Ginger beer Ginger ale
Taste Stronger, spicier, often cloudy Milder, sweeter, usually clear
Typical use Moscow Mule, Dark and Stormy Sipping and light mixers

Safety note for home brewing

Home fermentation makes some alcohol and pressure. Use bottles made for fizzy drinks, open them slowly, keep them refrigerated once fizzy, and do not give a home-fermented drink to children or anyone avoiding alcohol. The alcohol level of a home brew is hard to predict.

Common mistakes

  • Using a starter that never bubbled.
  • Sealing bottles in a warm place for days without checking pressure.
  • Assuming every bottle labeled ginger beer was brewed.
