Does Kombucha Produce Methanol?

None of the studies on kombucha have shown the presence of methanol. Methanol production is linked to pectin content in the wort. Tea and sugar do not contain pectin and therefore cannot produce methanol.

Can kombucha become alcoholic?

The longer kombucha ferments, the longer it has to produce alcohol. The type of yeasts in kombucha also impacts the level of alcohol. Yeast that can ferment at lower temperatures will produce a lower-alcohol brew.

Is methanol produced during fermentation?

Methanol is produced during fermentation by the hydrolysis of naturally occurring pectin in the wort (Nakagawa et al. 2000; Mendonca et al. 2011). PME de-esterify pectin to low—methoxyl pectins resulting in the production of methanol (Chaiyasut et al.
