A glass carboy is a narrow-necked bottle used to ferment and age homemade wine. Glass does not absorb odors or scratch as easily as plastic, and it blocks oxygen well, which is why many winemakers prefer it for long aging.
The six carboys and jugs below come from home brewing suppliers that have sold glass for years. Sizes range from small one-gallon jugs for trial batches to full-size carboys. Exact volumes, neck sizes and stopper fits are the sellers’ own details, so check them on the listing. We have not used these products ourselves, so please confirm the size, finish and what is included on the current listing before you buy.
