You’ll Receive: 8 black 38 mm lids with airtight polypropylene seal gaskets, designed for both storage and to hold pressure during and after secondary fermentation.
For Storage & Fermentation Use: In addition to storage, these lids are commonly used for secondary fermentation in kombucha, water kefir, cider, beer, mead, seltzer, and more by keeping carbonation sealed in so your batch stays fizzy and fresh until ready to drink.
Fits Standard 38 mm Bottles: Fits Fermentaholics stout bottles and all standard 38 mm opening bottles, which include different types of store-bought kombucha bottles. While there is no standard universal “kombucha bottle” opening size, this lid size is popular in store-bought kombucha bottles and is the most common size found in growlers and carboys.
Versatile Usages: Includes bottling beverages like beer, wine, vinegar, oils, cold brew, and drinks to grab and go. Also great for storing water, iced tea, juice, soda, and more. Commonly used in fermentations and for holding carbonation in ciders and other brews. Can also be used for chemicals, solvents, or other compatible liquids. Ideal for capping growlers during a fill at your local brewery. Simple, reliable lids for everyday brewing and storage needs.
Durable and Reusable: Made of durable plastic and built for repeated use in fermentation, bottling, or storage. Helps reduce waste from single-use caps and bottles. Each cap includes a removable polyseal liner that can be gently popped out for easy hand washing.
