Dirty beer lines can lead to:
Sour or stale-tasting beer
Off-smells and poor aroma
Cloudy appearance
Flat or foamy pours
Customer complaints and product wastage
Beer is a food product, and like any perishable item, it’s vulnerable to bacteria, yeast, and mould buildup. Without proper cleaning, biofilm and residue will build up in the lines, negatively impacting both the flavour and safety of the beer being served.
At Cellar Maintenance Australia, we help pubs, bars, and hospitality venues protect the quality of their draught beer with professional, reliable servicing and education.
The industry standard is to clean beer lines at least every two weeks, though weekly cleaning is preferred in high-volume venues.
Your cleaning schedule should include:
Daily: Tap rinsing, bar hygiene, surface wipe-downs
Fortnightly: Full beer line flush with food-grade chemical
Monthly: Condenser cleaning and overflow checks
Quarterly to Annually: System inspections and gas safety checks (AS5034 compliant)

Turn off your glycol chiller
Disconnect keg couplers and attach to washout canister
Rinse lines with fresh water until clear
Sanitise using beer line cleaner (e.g., Lancer Redline) for recommended duration (typically 2 hours)
Final rinse with water until no residue or colour remains
Reconnect kegs, turn chiller back on, and pull beer until it runs clear
Pro Tip: Always wear PPE and use pH strips to ensure all chemical residue is fully flushed.
Even the cleanest beer lines won’t help if your glassware is dirty. Make sure all glasses are:
Free from lipstick, grease, detergent film or food residue
Rinsed with cold water before pouring
Undamaged (no cracks or chips)
Beer Clean Test:
A clean bar means better beer. Here’s a simple checklist:
Daily
Clean taps and drip trays with hot water
Rinse tower/fount with clean water
Avoid perfumed or bleach-based sprays near glassware
Wipe down all visible surfaces and chiller exterior
Weekly
Your cooling system plays a huge role in beer quality. Poor performance = foamy, warm, or flat beer.
Monthly
Clean condenser coils
Check overflow trays and drain pipes
Ensure fan and agitator are free of scale
Quarterly to Annually
Test glycol concentration
Service refrigeration units and manifolds
Inspect gas systems (in accordance with AS5034)
