Kefir vs yogurt: what's the difference?
Kefir and yogurt both start with milk and a culture, but they set at different temperatures, take different times and taste very different.

Both start the same way — warm milk, a sachet of culture, time — and both end up tangy and fresh. But they are different foods, and the difference starts with the bacteria.

Yogurt
Yogurt cultures like heat. Kept at about 43 °C they work fast and set the milk firm in a night. The result is something you eat with a spoon — plain, with fruit, or strained into a thick spread.
Kefir
Kefir cultures work at a lower temperature — 35–40 °C — so they take longer, 12–14 hours, and set the milk more loosely. It stays drinkable, with a gentle sourness and sometimes a light sparkle from the yeast in the culture.
Which one to choose?
If you want breakfast in a bowl, start with yogurt. If you want something to drink, go for kefir. If you cannot decide, the yogurt & kefir set has a box of each.
