Fermented vegetables are delicious, loaded with probiotics and easy to make at home. Mason jars are the perfect vessel to ferment in: they're easy to find, fit perfectly in kitchen cupboards, are dishwasher safe and versatile. That's why Masontops created an entire suite of products for fermenting vegetables in Mason jars, including Pickle Pipes. Our patented Pickle Pipe airlocks are the easiest way to vent fermentation gas. The one-way valve automatically releases gas, without letting in any oxygen that can cause spoilage. This means no more having to regularly monitor and manually 'burp' your jars during fermentation. We recommend using this product with food-safe glass fermentation weights, like our Pickle Pebbles.
