Whether you could add a tea taste in tge second ferment, I am not sure but you could try. **Q: Thank you the kefir arrived. May i leave it in the freezer for a week before i carry it abroad?** A: You are welcome! You need to dry the grains on the unbleached pergamin paper before freezing them. **Q: can you make kefur with plant based milk?** A: I use "Water Kefir Grains" to make Water Kefir! Kefir grains are different for making milk kefir as far as I understand. Albeit you are asking about "plant based milk" … I'd assume you need the "Milk Kefir" grains?! **Q: How long can i keep it in its packaging before culturing. Do i put the package in the fridge before taking it abroad as a gift cos u don't ship overse** A: I kept mine in a fridge for a day before culturing. I would not keep it much more than 2 or 3 days in the fridge if you can help it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great grains *by D***T on 24 March 2026* Got these for my wife as she doesn't like my kefir milk!
