There are several ways to brew ginger beer:
- With the help of a ginger bug: the ginger bug is a batch liquid that can be grown with ginger and sugar from the wild microbial flora of ginger.
- With a so-called Ginger Root Plant or Ginger Beer Plant: This culture is very similar to water kefir crystals and is also a SCOBY (symbiosis of yeasts and bacteria). It consists of crystal-like granules, but they are usually somewhat rounder than those of water kefir. Water kefir crystals specially converted to ginger are also often available under the name Ginger Root Plants.
