GreenWise
Fermentation weights

The fermentation weights from the GreenWise brand promise hygienic fermentation with simple and safe use. They are made of high-quality, food-safe glass, which is essential for hygienic fermentation . The smooth surface of the weights prevents the formation of mold, ensuring a clean and healthy fermentation. The weight fit has been specifically designed for general purpose jars and fits perfectly into wide mouth mason jars or other jars with a diameter of more than 7 cm. This means they sit firmly and securely in the jar without slipping or interfering with the fermentation process. The non-slip handle on the weights makes them easy to insert and remove without direct contact with the brine. This is not only practical, but also hygienic, as no impurities can get into the fermented food. A special feature of the manufacturer GreenWise is that it donates a portion of each set of fermentation weights sold to the climate protection organization myclimate Germany. This offsets 10 kg of CO₂ per set, which contributes to sustainable production and promotes environmental protection. One point of criticism is the use of foam for the packaging, which is unfortunately not environmentally friendly.

Advantages

✅ Made from food-safe glass
✅ Safe against mold growth
✅ Non-slip handle
✅ Donations to climate protection organization

Disadvantages

❌ Packaging not environmentally friendly

❌ No instructions for use
