Overview
A home keg system gives you pub-quality carbonated beverages on demand. Ball-lock Cornelius kegs, a CO₂ tank, a dual-gauge regulator, and a tap — this guide covers each component and how to set them up together. This guide breaks down specifications, compatibility, and practical setup to help you make a confident decision for your specific carbonation needs.
Choosing for Your Use Case
Before buying any carbonation equipment, understand your daily usage. Light users (under 0.5L/day) need different equipment than heavy users (2L+/day). Use the CO₂ Cost Calculator to see exact break-even points for any upgrade.
Key Compatibility Standards
The CGA-320 valve is the standard connection for home carbonation in North America. Almost all consumer CO₂ tanks, regulators, and adapters use this threading. Verify CGA-320 compatibility before purchasing any component to ensure it integrates with your existing equipment.
Safety First
All pressurized CO₂ equipment requires proper care. Always secure tanks upright, check connections with soapy water monthly, and store away from heat sources. See the CO₂ Safety Guide for comprehensive indoor safety guidance.
