Kefir vs. Yogurt — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on May 15, 2024
Kefir is a fermented milk drink with a tart, slightly fizzy taste and contains multiple strains of yeast and bacteria, while yogurt is a creamy dairy product cultured primarily with bacteria, resulting in a thicker texture and tangy flavor.

Key Differences
Kefir is made by fermenting milk with kefir grains, which are a combination of yeast and bacteria. This process not only gives kefir a distinct tart and slightly effervescent quality but also makes it rich in probiotics. While yogurt is produced through the fermentation of milk by specific bacteria, primarily Lactobacillus bulgaricus and Streptococcus thermophilus, resulting in a creamy, smooth texture that is less fizzy and generally thicker than kefir.
The probiotic content of kefir is typically more diverse than that of yogurt, containing several major strains of friendly bacteria and yeasts. While yogurt also offers probiotic benefits, it usually contains fewer strains, focusing mainly on improving gut health and enhancing digestion.
Kefir often has a thinner consistency, making it drinkable. While yogurt’s thicker texture lends itself well to being eaten with a spoon, and it is often used as a substitute for cream or mayonnaise in recipes or served with mix-ins like fruit or granola.
The taste of kefir can vary from mildly to sharply tart, and it may have a slight fizz due to carbon dioxide, the byproduct of yeast fermentation. While yogurt generally has a consistently tangy flavor, which can vary in intensity depending on the specific cultures used and the fermentation duration.
Nutritionally, both kefir and yogurt are excellent sources of calcium, protein, and B vitamins. However, kefir may have the added advantage of having more bioactive compounds due to the presence of both bacterial and yeast cultures, which can contribute to improved digestion and potentially broader health benefits.
