What Is Kefir?
Kefir is a fermented milk drink with a tangy taste and creamy texture. It originated in Eastern Europe and has gained popularity worldwide as a nutritious beverage.
The drink is made by adding kefir grains to milk, typically cow’s milk, though goat’s or sheep’s milk can also be used. These grains are not actual cereal grains but rather clusters of bacteria and yeast.
During fermentation, the microorganisms in kefir grains multiply and transform the milk’s lactose into lactic acid. This process gives kefir its distinctive flavor and slightly effervescent quality.
Kefir has a consistency similar to drinkable yogurt but contains a more diverse range of probiotics. These beneficial bacteria and yeasts contribute to kefir’s potential health benefits.
The fermentation process typically takes 24 to 48 hours. Once complete, the grains are strained out and can be reused to make new batches of kefir.
While traditional kefir is dairy-based, non-dairy alternatives made from coconut water, fruit juices, or plant-based milks are also available. These options cater to those with lactose intolerance or dietary restrictions.
Kefir can be consumed plain or flavored with fruits, herbs, or sweeteners. It’s often used in smoothies, as a base for dips, or as a substitute for buttermilk in baking recipes.
