Frequently asked questions about this product

What makes this silicone stopper versatile for fermentation?

It has two separately sealable outputs, so you can attach an airlock, siphon and precision thermometer through one stopper while keeping the vessel airtight.

How do I get an airtight seal with this stopper?

Press the food-grade silicone stopper firmly into a correctly sized opening; its elasticity conforms to the neck to create the hermetic seal that protects the contents during fermentation.

What should I do with the outputs I am not using?

Each output can be sealed separately, so close any opening you are not using to keep the vessel airtight while still monitoring fermentation through the others.

How is the stopper cleaned and cared for?

Being food-grade silicone it is easy to clean and reusable; wash it after each use so residues do not affect the seal or the next batch.
