Pourabucha Kombucha is a bottle shop at 28 Gambas Crescent, Woodlands Food Express, Sembawang, Singapore, rated 4.8 from 32 Google reviews.
A kombucha shop is easiest to use when you know how the drink is made and kept. Kombucha is a fermented tea, so check the label for the alcohol content, which is usually low but not always zero. Keep bottles cold, since the fizz and flavour change with heat, and check the best-before date. Ask whether the drink is pasteurised, and what flavours are made in small batches. Regulars often try one flavour at a time and buy a few bottles of the one they like.
Gambas Crescent is an industrial and logistics area in Sembawang, so the shop mostly serves people who work nearby or drop in for a quick bottle on the way.
