Watch kefir being made

How gently should you move the grains in a strainer? When does fruit juice go in? Some details are easier to grasp when you see the movement. Start with two kitchen techniques, then look at kefir through a microscope.

A gentle movement through the strainer

Gently strain out the milk-kefir grains

Watch the spoon move gently through the kefir in the strainer. The drink drains into the bowl while the grains stay behind.

English excerpt · 5:04–5:38. This clip shows straining; use the written method for ingredients, timing and refrigeration.

From fresh orange to flavouring

Prepare fresh orange juice for water kefir

Fresh orange is pressed on a citrus juicer before the juice is added to strained water kefir. Flavouring the finished drink is a separate step from feeding the grains.

English excerpt · 5:46–6:24. Watch the juice-preparation step. For an easy serving option, mix juice into the finished drink and refrigerate it. Sealed fermentation can build pressure and alcohol; the full video is not our bottling guide.

What changes when you look closer?

Dense clumps obscure the view at first. Switching to phase contrast makes small cells easier to see. Shapes and movement alone cannot identify a strain or prove a health benefit.

Unsure about a batch?

If its appearance, smell or handling history raises a concern, start with the safety guide. Do not taste a suspect batch to decide whether it is safe.
