So the third vertical line up from the bottom is the 3 gallon mark?** A: Thanks for asking. The horizontal ridges do not measure volume increments. They exist for structural purposes and give the carboy added strength. To determine volume increments, you can use a 1 gallon jug to fill up the carboy 1 gallon at a time and use a marker, sticker or tape to mark each increment. Thanks! **Q: Where is the bottle made? on the bottom of the bottle it should say where it is made.** A: Thanks for shopping. Our 3g carboys are produced in Italy. Thanks! **Q: Largest coin that will fit?** A: The opening is 1 in a quarter inches. ## Frequently Bought Together - Geo Sports Bottles 3 Gallon Round Glass Carboy Fits 30mm Cork Finish or 55mm Push Cap Home Brew (Clear Glass) (BT3GG) - Blue Dew Cap Replacement (2Pk) - Carboy Handle, 2 Pack Glass Carboy Handle Heavy Duty Carboy Holder for Smooth Neck 3 Gallon 5 Gallon 6 Gallon 6.5 Gallon Glass Carboys for Fermenter Wine Making Beer Brewing Home Brewing Equipment --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/40822981-3-gallon-round-glass-carboy-fits-30mm-cork-finish-55mm](https://www.desertcart.jp/products/40822981-3-gallon-round-glass-carboy-fits-30mm-cork-finish-55mm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-29*
