A 3 Gallon Glass Carboy with a 30 mm neck width, wide body, and ribbed sides. It is commonly used in the primary fermentation of wine and beer, though it can also sometimes be used for secondary fermentation as well. Glass carboys are often used during the fermentation process for homemade brewed beer, wine ales, hard cider, and mead.  The 3 gallon size is useful for splitting up larger batches. 

Caps sold separately.  Takes #7 stopper or universal carboy bung.
