This large 6.5 gallon size carboy fermenter is great for 5 gallon batches as there is extra head space to avoid blow-off during fermentation. This carboy has a smaller threaded neck than standard carboys, and requires a specific hood for use with racking, and fermenting. Threads are on the outside of the neck and won't interfere with a standard rubber stopper. Made in Italy. Our Italian glass carboy fermenters are made of consistent, thick, high quality glass. This glass carboy seals with a Small Universal Stopper (#6-7) or a standard #6.5 Rubber Stopper.
