16 oz Clear Swing-Top Kombucha Bottles – 12 Pack

12-Pack of 16 oz Clear Swing-Top Bottles

These reusable 16-ounce clear glass bottles are designed for kombucha second fermentation—the bottled step where brewers add flavor and build carbonation. The airtight swing-top closures, also called flip-top, swing-top, or Grolsch-style caps, help keep carbonation inside each bottle.

Sized for up to two gallons of Kombucha

Each gallon generally fills six bottles after starter tea is reserved, so twelve bottles can handle up to two gallon-sized batches or keep a second set ready for the next brew. The 16-ounce size is convenient for taking kombucha on the go or pouring multiple smaller servings.

Why Choose Clear Glass?

Clear glass is ideal when you want to see the color, fruit, herbs, or other flavoring ingredients inside. Because clear glass does not block as much light as amber glass, keep the bottles in a dark, room-temperature space during second fermentation; an empty cooler works well.

Reusable for Batch After Batch

These high-quality bottles are made for repeated brewing use. They are dishwasher safe, making it easy as can be to clean and prep for the next batch. 

Frequently Asked Questions

What are these bottles used for in kombucha brewing?

They are used after primary fermentation. Transfer the kombucha into the bottles, add flavoring ingredients, seal, and allow the bottled kombucha to develop flavor and carbonation during second fermentation.

How many bottles do I need for a gallon batch?

Six 16-ounce bottles are a practical match for a gallon-sized brew after starter tea is reserved for the next batch. Actual yield depends on how much starter tea you save and how full each bottle is.

What else can I use these for?

These bottles are excellent for a wide variety of uses. We have heard success stories from our customers on kombucha, ginger bug/homemade soda, limoncello, tea storage, water bottles for guests, and even more. These bottles were built to last and can be used for many things over the years.
