Is kefir suitable for a vegan diet?

Is kefir vegan?

Classic kefir is not vegan. It is milk (usually cow, goat or sheep) fermented with kefir grains, so it is an animal product. The answer changes only if the kefir is made from something other than milk.

Which kinds of kefir are vegan?

• Water kefir: grains ferment sugar water or fruit juice instead of milk. It is dairy-free, lightly fizzy and can be flavored.
• Coconut water kefir: made with water kefir grains in coconut water. This is the option for avoiding every trace of dairy.
• Coconut milk or nut milk kefir: a creamy, tangy, yogurt-like drink. Whether it is truly vegan depends on the starter, see below.

Why the starter matters

Milk kefir grains and powdered kefir starter cultures are kept in milk. Cultures for Health says coconut milk kefir made with them can have very little or no dairy exposure, so it may still contain some dairy, and milk grains need to go back into dairy milk from time to time to stay healthy. It says water kefir grains avoid dairy traces.

How to check a store-bought kefir

• Read the first ingredient. Cow’s milk, goat’s milk or milk solids mean it is dairy.
• Look for a plant base named on the front: coconut, coconut water, cashew, oat, soy or just water and fruit.
• Be careful with flavor names. A product called coconut kefir can still be milk-based, so read the allergen line for the word milk.
• If you are strictly vegan, look for a vegan label or ask the maker which culture they use.

Making vegan kefir at home

The simplest path is water kefir grains in sugar water, juice or coconut water. Cultures for Health says to activate the grains in sugar water first and alternate batches between sugar water and coconut water to keep them healthy. Use clean jars and follow the grain supplier’s instructions.

Is it a one-to-one swap for dairy kefir?

No. Water kefir is thin and sweet-tart, and coconut versions taste of coconut. They are different drinks, so choose by taste and diet, not by assuming they match dairy kefir.
