Stricts levels of hygiene are essentials! 

Hygiene compliance is essential while preparing milk kefir beverages. Therefore, it is very important to always pay attention to hygiene when it comes to kefir.


If you notice any unusual smell and/or colors, or if mold appears on your kefir seeds, you must not drink the beverage obtained. Milk kefir seeds that smell strange are usually grey or brown.


Healthy kefir seeds have naturally a slightly acidic smell, no aftertaste. Always use kitchen tools easy to maintain (glass jar, fine mesh plastic strainer, small plastic spoon).


In order to wash the kitchen tools, you do not have to sterilize them; by cons, always use hot water and dish detergent preferably made of natural products, and take care not to burn yourself when doing this.


For the jar, you can use glass jars for vegetables for e.g., that you can easily find on the market. You must carefully clean the jar before use, as described here.


Mesh plastic strainers and plastic little spoons being affordable, the best is to buy them new and used them only for your probiotic cultures.


Once the kitchen tools are cleaned as described, you have to let them cool completely, as kefir seeds can’t withstand high temperatures. Only after that you can start a new culture.
