Under the hood

128 ounces per gallon. Honest math.

US standard keg sizes and pour-yield rules from Brewers Association sizing guidance, with cost references typical of a US wholesale market.

  1. 01

    Total fluid ounces

    Keg gallons × 128 oz/gal. Half-barrel = 1,984 oz, sixtel = 660, mini = 169.

  2. 02

    Wastage subtraction

    Multiply total oz by your wastage % (typically 5–15%) and subtract before dividing into pours.

  3. 03

    Pours and case-equivalents

    Usable oz ÷ serving size = pours. Total oz ÷ 12 ÷ 24 = case-equivalent (24-pack).

Questions

Frequently asked

A well-tuned kegerator with proper CO₂ pressure (10–14 PSI) and clean lines wastes 5–10%. Anything above 15% means foam problems — usually pressure too high or temperature too warm.
