Fermented lemonad – orange

Zester is based on water kefir. It is a fascinating and delicious non-alcoholic drink that, until recently, came with several practical challenges, namely:

1. Difficult to scale in production

2. A cold chain that is extremely energy-intensive

3. A product that is unstable or overly acidic

→ These challenges made water kefir, until recently, impractical for retail, horeca and foodservice. Zester fermented lemonade offers a clear solution.

How Zester innovates

Zester innovates by introducing a sustainable water kefir to the market that eliminates the cold chain. Using a unique fermentation technique, we create a fermented lemonade that is stable, long shelf-life and scalable.
How? We allow the water kefir to ferment until the flavour is perfectly balanced, then stop the process at exactly the right moment.

You may be wondering: “What about the health benefits?” We cannot share everything here, but they are numerous (less sugar, low cal, postbiotics, …).

The benefits of Zester fermented lemonade

• 18 months shelf life at ambient temperature

• no energy-intensive refrigeration required

• low cal, more flavour, less sugar

• easy to implement and use
