What is the typical carboy capacity?

• A. 1-2 gallons
• B. 50-100 gallons
• C. 100-200 pounds
• D. 5-15 gallons

Answer: (D)

Carboys are sized for manageable handling while storing or transporting liquids, and the most common single-container size is around five gallons, with some carboys going up to about fifteen gallons. That 5–15 gallon range fits typical use and handling considerations, making it the best match among the options. A one- to two-gallon size is smaller than what’s usually referred to as a carboy, while fifty to one hundred gallons is more like a drum or tote, not a carboy. The option expressed in pounds is a weight, not a capacity, and doesn’t describe how much liquid the container can hold. So, five to fifteen gallons is the typical carboy capacity.
