## Overview

The Sauer System Fermentation Airlocks 4-pack transforms any wide mouth Mason jar into a professional-grade fermenter with an automatic degassing water barrier, ensuring perfect anaerobic conditions for kimchi, sauerkraut, pickles, and more.

## Description

Product Description The Fermentology Sauer System uses water to create an oxygen barrier that handles burping bubbling ferments automatically so you don’t have to. This is an easy DIY pickle method and makes fermenting and pickling a breeze. All you need to do is add your fresh vegetables to a wide mouth Mason jar, pour in a salt water brine, set up the complete airlock system and let Fermentology do the rest. When the ferment is complete, you’ll have tangy, sour and probiotic nourished vegetables that are a great source of vitamins. Simply remove the airlock and add the silicone stopper to turn the airlock lid into a sealed Tough Top for fridge storage. Each airlock setup includes 1x airlock, 1x Tough Top lid (includes silicone gasket and grommet), and a silicone stopper; 4 airlock setups come in a pack. Make kraut, like premium probiotic sauerkraut, pickles, garlic vegetable mixes, and traditional German, Polish and Chinese dishes, or try your hand in brewing homemade kombucha, mead, super kefir and kvass. You can even ferment your own garden harvest, like peppers, carrots, and more! The Fermentology Sauer System can be used with a variety of other Fermentology or Masontops supplies, including a fermentation weight, pebble or stone, pounder, tamper, storage top, and reused for year upon year of use. You can get all your equipment for fermenting from Fermentology! Make Sauerkraut, Pickles, Kimchi and More The Sauer System is designed specifically for fermenting in Mason jars. All you need are some glass jars with a wide mouth, your favorite veggies, and some salt. Mason and canning jars are perfect for fermenting in because of their convenient size and popularity – you probably already own many! Traditional and Reliable Method Water barrier airlocks are a tried-and-true way to keep oxygen from spoiling ferments, while also automatically venting gas build up. The inner chambers of the Fermentology Sauer System are strategically designed to effectively block air and vent gas so you don’t need to worry about your prep going to waste! Make Probiotic Superfoods Fermented vegetables are a good source of probiotics and are easy to make at home. When a vegetable is fermented, it not only takes on a pleasantly sour and tangy taste and becomes naturally preserved, but it also maintains it’s original nutrients with the addition of probiotics. Includes Storage Lids and Stoppers Each airlock equipment set up includes a grommet fitted lid that either an airlock or stopper can be fitted into, depending on if you’re in fermenting or storing mode. The included Mason jar top is fitted with a silicone gasket for an airtight seal and can serve a number of uses besides fermenting! Sized for Everyday Use Ceramic crocks and large fermenting containers take up a lot of unnecessary kitchen space in your home fermentation station. Mason jars and the Sauer System are the perfect set up for the every day home fermenter. Active ferments can easily be kept in kitchen cupboards and drawers to save counter space and reduce clutter. Food Safe, Quality Materials All Fermentology products are made of food safe and high-quality plastics and silicones. The items included in this box kit are BPA-free and phthalate-free. All of our fermenting equipment is designed in-house by a group of avid fermenters in Toronto, Canada. Part of a Suite of Fermentation Products This set is one of many fermentation tools Fermentology has to offer. Our other products include waterless airlocks with pumps, fermentation weights, and vegetable tampers. We have equipment for all styles and levels of experience when it comes to lacto fermenting vegetables.

Review: Great System - This is a very good system for fermenting small batches imo, especially if one is into canning too, because jars become multi-purpose. I have five on the go currently, and I will be adding today's picked gherkins, and would have more fermenting if it wasn't for one major issue - desertcart Prime are now using Evri and our last few orders of this product have disappeared/been returned. Anyway, rant over. The lids are solid and easy to clean and beat any other small-batch system that I have used by a country mile. For large batches I use traditional crocks, but wouldn't hesitate to use these if I had suitable >2litre jars. Their glass weights are good too.
Review: do what they are meant to - good fit in my fermentation system do their job well.
