Ball Lock Kegs

BeverageCraft carries new 304 stainless steel ball lock kegs for homebrew beer, cold brew coffee and other draft beverages. Also known as Cornelius or Corny kegs, these models have separate gas and liquid posts and a removable lid for filling and cleaning. Choose from stackable and non-stackable designs.

Choose Your Corny Keg Size

We stock four nominal sizes:

  • 1.5 gallon (6 L): for test batches and samples. Available in stackable and non-stackable designs.
  • 2.5 gallon (10 L): for smaller batches or splitting a 5-gallon batch between two kegs.
  • 5 gallon (19 L): for standard 5-gallon homebrew batches, with rubber top handles and a protective rubber base.
  • 10 gallon (38 L): for larger batches. Its short, wide body requires more fridge floor space than the smaller models.

What to Look for When Choosing Ball Lock Kegs

  • Dimensions: compare the keg's height and diameter with your fridge's internal dimensions and door opening. Allow extra clearance for disconnects and tubing.
  • Construction: stackable models are shaped to sit on compatible kegs for storage. Check stacking compatibility before ordering. Rubber handles and bases help with carrying and surface protection.
  • Material: 304 stainless steel resists corrosion. Clean it with a non-chlorinated brewery cleaner suitable for stainless steel, following the product instructions. Avoid household bleach, which can cause pitting.
  • Pressure rating: follow the maximum pressure specified for your model. Tubing, fittings and dispensing equipment must also suit your operating pressure.
  • Connections: match gas and liquid disconnects to their corresponding posts. Pin lock connectors are not interchangeable with ball lock connectors; see our ball lock vs pin lock comparison.

This category also includes a 5-gallon Corny/Sanke hybrid keg. It has a removable lid but uses a D-type keg coupler instead of ball lock disconnects. Choose this model for a system with a compatible D-type coupler.

Corny Kegs for Beer and Other Beverages

  • Homebrew beer, cider and mead: carbonate and serve on tap instead of bottling.
  • Cold brew coffee: serve chilled coffee on draft. Conventional nitro setups use N2 equipment and a stout-style faucet with a restrictor plate.
  • Kombucha: serve finished kombucha cold on tap. A dedicated keg and line help keep kombucha separate from beer service.
  • Soda, seltzer and sparkling water: carbonate and dispense with CO2. Set pressure for the beverage temperature and target carbonation, within the keg's rated limit. Dedicated seals and tubing help prevent root beer flavour carryover.
  • Wine and batched cocktails: dispense still wine with N2 or argon or prepare cocktails in batches for tap service.
  • Pilot batches and samples: use smaller kegs for brewery trials, tastings and limited releases.
