For those who want to get started right away: Our canning jars, fermentation sets and the canning starter set are perfect for any occasion and make canning even easier.

Before we dive into the details, let's take a moment to talk about the importance of sterilizing jars. Sterilizing eliminates germs, bacteria, and microorganisms that could affect the shelf life and freshness of your food. It is crucial to ensure that your homemade treats can be eaten safely.

Before you start, make sure everything is ready: clean jars, a large pot, water, optional vinegar, and a timer. Check your jars for cracks or chips. We recommend our canning jars – they are heat-resistant, oven-safe, and reusable. For the lid, our two-piece lids are particularly suitable, as they seal optimally and extend the shelf life of your food.

Before you start sterilizing, thoroughly clean your favorite jars with warm water and dish soap or simply in the dishwasher. Be sure to clean the lids and seals as well to remove any residue.

Fill a large pot with enough water to completely cover the jars. Optionally, add one tablespoon of vinegar per liter of water. The vinegar helps prevent limescale deposits and sterilizes the jars flawlessly.

Carefully place the cleaned jars in the pot of water, making sure they are completely submerged. Avoid overfilling so that each jar has enough space to be effectively sterilized.

Bring the water to a boil and then let the jars simmer gently for 10 minutes. The steam will help eliminate all germs and sterilize the jars.

After boiling, carefully remove the jars with tongs and let them dry on a clean towel or a prepared rack. Avoid drying the jars, as this could lead to contamination.

Once the jars are dry, you can fill and seal them with your preferred foods. Make sure the lids are tight to preserve freshness. Store the jars in a cool, dry place to ensure optimal conditions.

Alternatives to sterilizing in a water bath:

1. Sterilizing jars in the microwave: Place the clean jars in the microwave and heat them on high power for 1-2 minutes. Make sure the jars do not overheat and let them cool down before filling them.
   
   

2. Sterilizing jars in the oven: Place the clean jars and lids on a baking sheet and bake them at 120°C for about 10 minutes. Carefully remove them and let them cool before use.
   
   

3. Sterilizing jars in the dishwasher: Some modern dishwashers have a sterilization program that can also be used for sterilizing jars. Place the jars and lids in the dishwasher and use the appropriate program for thorough sterilization.

To ensure your sterilization process runs smoothly, here are some additional tips:

• Use fresh ingredients: Fresh foods contribute to a longer shelf life.
• Check jars for cracks: Damaged jars cannot be effectively sterilized, so make sure they are in perfect condition.
• Keep utensils clean: Both tongs and the pot should be thoroughly cleaned before each use to prevent contamination.
