    What Size Keg Do I Need? A Simple Guide for Bars, Cafes, and Offices

    Keg Sizes, Demystified

    If you've never ordered a keg before, the sizing can be confusing. Here's a plain-English breakdown.


    The Three Sizes You'll See

    Sixtel (1/6 Barrel)

    • Volume: 5.16 gallons / ~55 twelve-ounce pours
    • Best for: Cafes, small offices, testing a new flavor
    • Dimensions: 23⅜" tall × 9¼" diameter

    Quarter Barrel (1/4 Barrel)

    • Volume: 7.75 gallons / ~82 twelve-ounce pours
    • Best for: Medium offices, boutique bars, events under 100 people
    • Dimensions: 13⅞" tall × 16⅛" diameter (short and wide - "pony keg")

    Half Barrel (1/2 Barrel)

    • Volume: 15.5 gallons / ~165 twelve-ounce pours
    • Best for: High-traffic bars, large offices, events over 100 people
    • Dimensions: 23⅜" tall × 16⅛" diameter

    Quick Decision Matrix

    Venue Type Weekly Volume Recommended Size
    Cafe / coffee shop 20-40 drinks Sixtel
    Small office (15-30 people) 30-60 drinks Sixtel or Quarter
    Large office (50+ people) 80-150 drinks Quarter or Half
    Bar (moderate NA demand) 40-80 drinks Quarter
    Bar (strong NA program) 100+ drinks Half
    Wedding / event (one day) Varies See our event calculator

    Pro Tips

    1. Start small: Order a sixtel first to gauge demand, then scale up

    2. Rotation: Swap flavors between keg orders to keep things fresh

    3. Shelf life: NA kegs stay fresh for 45-60 days once tapped (longer than most craft beer)
