The classic glass carboy, ideal for use as a primary or secondary fermenter. The 5 gallon size is ideal for use as a secondary fermenter. Glass is completely nonporous, and has the advantage of allowing a good look at the fermenting beer. To make sure they arrive in one piece, our Glass Carboys are packed in a special double box and are guaranteed to arrive unbroken. Made in Italy. 19½" tall, 10½" wide.
NOTE: This item weighs about 17 lbs. total, and actual Fedex Ground shipping based on your delivery zip code will be charged at checkout.
WARNING
Glass carboys are easy to break when full and especially when wet. We urge you to wear protective gloves when handling full glass carboys, as a broken glass carboy can send you to the emergency room.

Q: I find that there is a lot of variability in these carboys. Do they hold a full 5 gallons and still leave some headspace for an airlock? I have one that is 4.75 gallon to the top rim and the other is 5 gallon at the very top rim.
A: We find ours are pretty consistent at 5 gallons, although minor variations can occur.

Glass isnt thick enough
Glass isnt tempered well and does not interact well with hot water temps. William's Brewing Responds: Yes, our carboys are not designed to handle hot water temperatures. We recommend these for cooled wort use only.
