Frequent questions about Prokey's water kefir drinks

Has ProKey to be refrigerated?

You don’t need to refrigerate ProKey during transport or storage, but you should eat it cold, it will be tastier.

What is ProKey water kefir self-life?

Expiration date of Prokey soft drinks is a year since they are made. Its flavour evolves slightly over time but really does not spoil. As it does not contain proteins and fats (like milk kefir), is not much else to spoil on it.

Over time kefir microorganisms are going to a state known as latency. It means, they are alive but asleep. The longer the kefir bacteria stay on latency more difficult to show its probiotic power. However they maintain their prebiotic power. With time Prokey becomes more prebiotic and less probiotic. But it is still a healthy soda.

Can you elaborate ProKey without sugar?

Definitely no. Sugar is the food for kefir cells. Sugar is used at the start of fermentation and when it has ended remaining unfermented sugar is minimal, not more than 0.5% over the total volume of water kefir drink.

You can make water kefir with another sweetener instead of sugar, like honey or agave, but then the kefir culture doesn’t grow very well and doesn’t consume all the sugars, resulting in sweet and with less probiotic power drink.

What are the differences between ProKey and milk kefir?

ProKey is a probiotic drink. It contains water, microorganisms and substances derived from their action and dissolved compounds from the lemon, dates and/or infusions we use in processing. So its digestion is very simple and its absorption fast.

In the case of milk kefir, the number of organisms per ml is much lower than water kefir, and it has lots of nutrients to absorb and digest (such as fats and proteins). Thus the milk kefir is a probiotic food, with less probiotic power than water kefir, but more nutritious capacity (more calories and macronutrients).
