Large 6.5 gallon size is perfect for 5 gallon batches as there is plenty of 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. Made in Italy. Italian glass carboys can be preferred to those made in China because the glass has a more uniform thickness. Dimensions: Height: 20.75 inches Width: 12.5 inches
