Your Draft System Has Worked Hard All Summer. Is It Ready for What's Next?

August is when many bar and restaurant owners should take a serious look at their draft beer systems.

Patio season has been busy.

Kegs have been turning over.

Bartenders have been pouring pint after pint.

Coolers have been opened hundreds of times.

Draft systems have been running through some of the warmest weather of the year.

And while everything may appear to be working, small problems can develop long before they become obvious.

A little extra foam can turn into wasted beer.

A small gas leak can turn into inconsistent pours.

A dirty beer line can turn into an off-flavour customers notice immediately.

A cooling problem can turn into a much bigger equipment issue.

August is the perfect time to stop, inspect your system and make sure your draft beer equipment is ready for the rest of the season.

Here's the practical checklist every bar, restaurant, pub and hospitality business should know.

Why August Is a Smart Time to Inspect Your Draft System

Summer puts additional demands on commercial draft beer systems.

Businesses may experience:

• Higher customer traffic
• Increased keg turnover
• More frequent pours
• Patio service
• Higher ambient temperatures
• More frequent cooler-door openings
• Increased equipment usage
• Greater beer volume and potential waste

The result?

Your draft system may have been working overtime for months.

A system that was performing perfectly in May may not be performing the same way in August.

That's why preventative maintenance matters.

🍺 August Draft Beer Maintenance Checklist

☑ 1. Check Your Beer Lines

Your beer lines are one of the most important parts of the draft system.

Beer travels through them every time a customer orders a pint.

Over time, beer residue and mineral deposits can accumulate inside the lines.

Check:

• When the lines were last professionally cleaned
• Whether beer has developed an unusual taste
• Whether pours have become inconsistent
• Whether excessive foam has developed
• Whether there are signs of buildup

Why it matters

Clean beer lines help protect beer quality and provide a more consistent customer experience.

If you can't remember the last time your commercial beer lines were professionally cleaned, August is a good time to check.

Northern Draft Bar Services provides professional beer line cleaning and draft system maintenance for commercial establishments.

☑ 2. Check Your Keg Cooler Temperature

Your keg needs to stay within the appropriate temperature range for the beer and draft system.

During summer, cooling equipment can experience additional workload.

Check:

• Cooler temperature
• Temperature consistency
• Air circulation
• Door seals
• Frost buildup
• Condensation
• Keg placement

Don't just look at the temperature once.

Look for consistency.

A cooler that fluctuates significantly throughout the day can contribute to draft performance problems.

☑ 3. Inspect Your CO₂ and Beer Gas System

Gas is an essential part of many draft beer systems.

Depending on the beer and system configuration, your setup may use CO₂ or a beer-gas blend.

Check:

• Regulator condition
• Pressure
• Gas tubing
• Connections
• Cylinder supply
• Signs of leaks
• Pressure stability

A common mistake

If beer isn't pouring properly, it can be tempting to simply adjust the regulator.

But changing pressure without identifying the underlying problem may not solve the issue.

Temperature, beer type, line length, system design and equipment all matter.

That's why professional CO₂ calibration and draft system troubleshooting can be important for commercial operations.

☑ 4. Inspect Your Keg Couplers

Your keg coupler is the connection between the keg and the draft system.

Inspect it for:

• Dirt or buildup
• Damaged seals
• Leaks
• Worn components
• Loose connections
• Proper engagement

A small problem at the keg connection can affect the performance of the entire system.

☑ 5. Clean and Inspect Your Faucets

The faucet is where your customer experiences the final result of the entire draft system.

A dirty faucet can affect:

• Beer flow
• Foam
• Taste
• Appearance
• Customer experience

Staff should be trained to:

• Keep faucets clean
• Open the faucet fully
• Avoid touching the faucet to the beer
• Report sticky or damaged faucets
• Follow proper cleaning procedures

Remember:

A clean glass doesn't fix a dirty faucet.

☑ 6. Check Your Glycol System

If your commercial draft system uses glycol cooling, don't forget about the equipment responsible for maintaining the temperature of the beer lines.

Check:

• Glycol temperature
• Pump operation
• Circulation
• Reservoir condition
• Tubing
• Connections
• Overall system performance

If your beer is cold in the keg but warm or inconsistent at the faucet, the cooling system deserves attention.

☑ 7. Inspect Your Draft Tower

Your draft tower contains important components that directly affect the final pour.

Inspect:

• Faucets
• Shanks
• Beer lines
• Connections
• Temperature
• Insulation
• Visible condensation or damage

The draft tower shouldn't be treated as just decoration sitting on top of the bar.

It is part of the beer delivery system.

☑ 8. Check for Beer Waste

Here's a question every bar and restaurant owner should ask:

How much beer are we pouring down the drain?

Look at:

• Excessive foam
• Over-pouring
• Slow pours
• Leaking equipment
• Incorrect pressure
• Poor pouring technique
• Beer left in lines
• Keg connection problems

Small amounts of waste can add up over time.

Reducing unnecessary beer loss can help pro

☑ 9. Review Staff Pouring Technique

Even a professionally maintained draft system can have problems if staff aren't pouring correctly.

Make sure employees understand:

Use a clean glass.

Hold the glass correctly.

Open the faucet fully.

Don't allow the faucet to touch the beer.

Don't partially open the faucet.

Report unusual foam or pouring problems.

Your staff are often the first people to notice a draft system problem.

Permit them to speak up.

Protect your beverage margins.

☑ 10. Look for Small Problems Before They Become Big Problems

Don't wait until the system stops working.

Watch for:

• Increasing foam
• Slow pours
• Warm beer
• Flat beer
• Off-flavours
• Gas pressure changes
• Leaking connections
• Strange equipment noises
• Temperature fluctuations
• Repeated customer complaints

A recurring small problem is often worth investigating before it becomes an emergency.

🍺 Your August Draft System Quick Check

Save this checklist for your next staff meeting:

☐ Beer lines professionally cleaned

☐ Keg cooler temperature checked

☐ CO₂/beer-gas pressure checked

☐ Gas connections inspected

☐ Keg couplers inspected

☐ Faucets cleaned

☐ Draft tower inspected

☐ Glycol system checked

☐ Beer waste reviewed

☐ Staff pouring technique reviewed

☐ Recurring draft problems documented

☐ Equipment requiring professional service identified

💰 Your Draft System Can Affect Your Bottom Line

Draft beer isn't just about serving a great pint.

It's also about protecting your product.

Excessive foam means beer that doesn't reach the customer.

Poor temperature control can create pouring problems.

Dirty lines can affect beer quality.

Gas problems can create inconsistent pours.

Equipment leaks can create unnecessary waste.

And repeated draft problems can affect customer satisfaction.

Your draft

A Draft Beer System Is More Than a Keg

This is one of the most important things for every bar and restaurant owner to understand.

A commercial draft system can involve:

Keg → Coupler → Beer Gas/CO₂ → Regulator → Beer Line → Cooling → Shank → Faucet → Glass

Every component plays a role.

If one part isn't functioning properly, the final pour can suffer.

That's why simply changing a keg, turning up the pressure or cleaning the faucet may not solve a recurring problem.

The entire system needs to work together.
