Review: Great product - I started a new hobby of making mead last year with the purchase of my 1st carboy. To expand my fun, I ordered another this year. This years purchase was defective, with an odd glass "string" inside (pic attached). I started the return process, with the option of a replacement being available, the new one was delivered in 2 days. I was given plenty of time to ship the defective product back via the UPS store. Very pleased with the overall quality, cost, function and customer service. Review: All Good - It's heavy with water in it, and a hazard. Buy a lift ring, for sure. But I've been using them for years to get Alkaline water at Whole Foods for my wife. Settles her stomach wonderfully. However, when you drop one on another, at least one of them tends to break. I think the ribs give it some structural integrity for transport to and from the store. My wife requires glass for water as plastic is apparently poisonous to her. (It's easier just to haul around these heavy things, getting 3 gallons instead of 5. I've used glass carboys for many years for making wine, and seen some comments about the warnings not to use in pressurized circumstances. I never had a problem with the old 5 gallon models without ribs. Technically, I don't think making wine pressurizes the carboy substantially. You put an airlock on it, and gas escapes under the most minor pressurization. As long as one doesn't use it for a champagne method, it's probably fine for wine. In fact, I've bought 3 gallon carboys just like this one at a wine-making shop. That being said, defective glass will break with little more than looking at it. ## Features - This 3-gallon glass carboy is perfect for fermenting beer, wine, cider, mead and more; The premium glass is impermeable to oxygen and protects beverages from contaminants - Carboy is scratch resistant, so users can scrub it clean without damaging the item; Unlike plastic, glass does not hold or absorb foul, eliminating the inconvenience of frequent cleaning - This bottle helps users reduce their carbon footprint - Country of Origin: Italy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01M0PK5KG | | Best Sellers Rank | #78,317 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #126 in Beer Brewing Bottles & Bottling | | Brand | Geo Sports Bottles | | Brand Name | Geo Sports Bottles | | Color | Clear Glass | | Customer Reviews | 4.6 out of 5 stars 1,037 Reviews | | Included Components | 3 Gallon Round Glass Jug | | Item Dimensions L x W | 16"L x 9"W | | Item Length | 16 Inches | | Item Type Name | 3 Gallon Round Glass Carboy | | Item Weight | 4.72 Kilograms | | Manufacturer | Geo Sports Bottles | | Material | Glass, Plastic, Rubber | | Material Type | Glass, Plastic, Rubber | | Nominal Wall Thickness | 0.25 inches | | Outside Diameter | 9 Inches | | Product Dimensions | 16"L x 9"W | | UPC | 841545115428 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Geo Sports Bottles - **Color:** Clear Glass - **Item Length:** 16 Inches - **Item Weight:** 4.72 Kilograms - **Manufacturer:** Geo Sports Bottles - **Material:** Glass, Plastic, Rubber - **Nominal Wall Thickness:** 0.25 inches - **Outside Diameter:** 9 Inches - **Product Dimensions:** 16"L x 9"W - **UPC:** 841545115428 ## Images ![3 Gallon Round Glass Carboy Fits 30mm Cork Finish or 55mm Push Cap Home Brew (Clear Glass) (BT3GG) - Image 1](https://m.media-amazon.com/images/I/71oI8pk+gKL.jpg) ## Questions & Answers **Q: Will it be safe to create a moderate vacuum in this Carboy?** A: I am not sure, however the glass is thick. **Q: Are the horizontal lines on these carboys gallon makers? 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***G on December 31, 2024* I started a new hobby of making mead last year with the purchase of my 1st carboy.

Better looking than the plastic ones *by A***R on September 25, 2022* After breaking our original one by accident, we purchased this one on Amazon to replace it. Very happy with the construction and the look. The price on Amazon was even cheaper than the store that we bought our original one from it. It also looks very nice and inviting on the counter. We now tend to drink more water because it’s there in front us. We would rather store our drinking water in glass too. ## 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.hr/products/40822981-3-gallon-round-glass-carboy-fits-30mm-cork-finish-55mm](https://www.desertcart.hr/products/40822981-3-gallon-round-glass-carboy-fits-30mm-cork-finish-55mm) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-11*
