📚 Keg Size Reference

Common Keg Sizes:

  • 1/2 Barrel (Half Keg): 15.5 gallons = 1,984 oz = 165 × 12oz servings = ~7 cases
  • 1/4 Barrel (Pony Keg): 7.75 gallons = 992 oz = 82 × 12oz servings = ~3.5 cases
  • 1/6 Barrel (Sixtel): 5.16 gallons = 661 oz = 55 × 12oz servings = ~2.3 cases
  • Cornelius Keg: 5 gallons = 640 oz = 53 × 12oz servings = ~2.2 cases
  • Mini Keg: 1.32 gallons = 169 oz = 14 × 12oz servings

Foam & Waste Factors:

  • Perfect Pour: Minimal foam, proper temperature (38-40°F)
  • Typical Loss: 10% due to foam, spillage, and line cleaning
  • Poor Setup: 15-20% loss from warm beer, bad lines, or improper pressure
  • First/Last Pours: Often foamier as system settles or empties

Tips for Maximum Yield:

  • Keep keg at proper temperature (38-40°F)
  • Use correct CO2 pressure for your beer style and line length
  • Clean beer lines regularly to prevent foam issues
  • Allow keg to settle for 1-2 hours after moving before tapping
  • Pour at 45° angle until glass is half full, then straighten
  • Use proper glassware - clean, room temperature glasses

Cost Savings:

  • Kegs typically cost 30-50% less per ounce than bottles/cans
  • No bottles or cans to recycle or dispose of
  • Perfect for parties, events, and homebrewing
  • Half barrel kegs offer the best value per serving
⚠️ Serving Responsibly: Whether pouring at home or hosting an event, always serve alcohol responsibly. Provide non-alcoholic options, ensure guests have safe transportation, and never serve to minors.
