Can I add fruit, herbs, juice, etc. to the kefir while the kefir grains are still culturing?
Yes, technically you can add fruit, herbs, juice, etc. to your kefir while the kefir grains are still culturing but use caution. Adding anything other than sugar and water while the kefir grains are present has a number of risks including contaminating the kefir grains and potentially damaging the kefir grains. For example, acidic fruits can damage the kefir grains by breaking down the yeast and bacteria that compose the kefir grains. Ideally, we recommend waiting to add flavorings until the culturing process is complete and the kefir grains have been removed. While this will mean a batch may take a day or two longer to make, it is normally worth preserving the integrity and long term health of the kefir grains.
