Product Description

This automatic venting high-boron-silica wine bottle is made of high-quality food-safe high borosilicate glass, non-toxic, BPA-free, lead-free and eco-friendly. Featuring exceptional thermal stability, it withstands extreme temperature changes from -20℃ to 170℃, preventing cracking during brewing, heating or cold storage. The thickened, crystal-clear glass body offers high transparency, allowing you to clearly monitor fermentation progress, wine color and ingredient status at a glance.

Designed with an integrated automatic one-way venting valve, it safely releases excess gas generated during fermentation to maintain optimal internal pressure, preventing bottle bulging or bursting while blocking outside air from entering. Paired with a food-grade silicone seal and secure locking lid, it delivers excellent airtightness to preserve wine aroma, prevent oxidation and extend shelf life.

The wide-mouth design simplifies adding fruits, herbs or other ingredients, pouring wine and thorough cleaning. Available in multiple capacities to meet diverse home brewing, commercial production and gift packaging needs.

Perfect for making and storing red wine, white wine, fruit wine, rice wine, herbal liquor, enzyme drinks and other fermented beverages. Suitable for home kitchens, wine workshops, bars, restaurants, gift sets and bulk wholesale for global buyers.
