Quick Answer
Draught beer consistently outperforms packaged beer because it bypasses the flavor-stripping effects of pasteurization and light exposure. To ensure you’re getting the best pint, choose high-traffic venues where kegs move fast and demand clean glassware with visible lacing.
- Prioritize bars that clean their lines every two weeks.
- Look for the “lacing” on the glass as proof of a pristine pour.
- Stick to keg-focused venues to avoid the stale, oxidized flavors of old bottles.
Editor’s Note — Priya Nair, Features Editor:
I firmly believe that if a pub isn’t pouring a clean draught beer, they don’t deserve your money. In my years covering international beer culture, I’ve seen far too many beautiful brews ruined by neglected lines and lazy pouring techniques. What most people miss is that the draught system is a living machine; it requires constant, obsessive maintenance. Alex Murphy is the perfect person to guide you through this because he treats his home kegerator with the same surgical precision as a professional cellarman. Stop settling for mediocre pints and start demanding better service tonight.
The sound hits you before the smell does—a soft, pressurized hiss, followed by the rhythmic clink of a glass against the font. Then comes the aroma. It’s that unmistakable, lifted scent of fresh hops or toasted malt, rising from a head of foam so thick you could practically stand a coin on it. That is the theatre of draught beer, and frankly, no bottle or can will ever touch it.
I’m taking a stand here: draught beer is superior to packaged beer in every metric that matters to a drinker. While I appreciate the convenience of a fridge full of cans, the draught experience is the only way to drink beer exactly as the brewer intended. It’s not just about the cold temperature or the theatre of the pour; it’s about the engineering of freshness. When you order from a tap, you’re engaging with a system designed to preserve the beer’s integrity from the moment it leaves the conditioning tank to the second it hits your palate.
The Myth of the “Better” Bottle
We’ve been sold a lie that bottled beer is somehow more refined or stable. The truth is that most mass-produced bottles and cans are pasteurized to survive the long, hot journey through warehouses and supermarket shelves. According to the Oxford Companion to Beer, pasteurization is a thermal process that kills yeast and bacteria, but it also strips away those delicate, volatile compounds that make a fresh pale ale or a crisp pilsner sing. You’re drinking a cooked version of the beer.
Draught beer, by contrast, is usually unpasteurized. It’s a living, breathing product that relies on the cold chain to stay vibrant. It’s the difference between a farm-fresh tomato and one that’s been sitting in a tin for six months. When you drink from a tap, you’re drinking closer to the source. You’re getting the beer in its most honest, unadulterated state.
Pressure, Gas, and the Science of the Pour
The magic happens inside the keg. By using a mix of CO2 and nitrogen, a well-calibrated draught system does two things: it maintains the precise level of carbonation the brewer dialled in, and it keeps oxygen—the absolute enemy of flavour—entirely out of the equation. Oxygen causes oxidation, which turns bright, hoppy beers into cardboard-tasting dregs in a matter of days.
The BJCP (Beer Judge Certification Program) guidelines place a heavy emphasis on the presentation of the beer, and for good reason. A proper pour isn’t just for show. That inch of foam, or head, acts as a physical barrier between the beer and the air. It traps the aromatics inside the glass, allowing you to experience the hop oils and malt esters before you even take a sip. If you’re being handed a pint with no head, you’re being shortchanged.
The Hidden Dangers of Neglected Lines
Even the best craft beer in the world will taste like a dirty penny if the draught lines aren’t pristine. This is the part of the process that separates the great bars from the ones you should walk out of. Yeast, bacteria, and beer stone build up in those lines faster than you’d think. If a venue isn’t flushing their lines with cleaning chemicals every two weeks, you’re tasting yesterday’s dregs.
Look for the lacing. When you finish your first few sips, the foam should leave rings of residue down the side of the glass. If the glass is clean, the foam clings. If the glass is greasy or the lines are dirty, the head will collapse, and the beer will look flat and uninviting. Don’t be afraid to send it back. A bar that values its product will thank you for noticing.
How to Drink Like an Expert
If you want to maximize your experience, you have to be selective about where you drink. I always look for high-turnover bars. A keg that sits on the tap for three months is a recipe for disaster. The Brewers Association 2024 guidelines on draught quality suggest that freshness is the primary driver of consumer satisfaction. If a bar has thirty taps but only two customers, turn around and walk out.
Choose the bar that focuses on a smaller, curated list of kegs. A place like The Local Taphouse in Melbourne or a similar high-volume craft beer bar is going to ensure their stock is rotating constantly. Freshness isn’t a luxury; it’s a requirement. When you’re at the bar, watch the bartender. They should rinse the glass before the pour to remove any dust or sanitizer residue, and they should never—ever—dip the tap nozzle into the beer. That’s a contamination risk that ruins the next pint for someone else. We write about these standards at dropt.beer because we believe you deserve the best possible version of your favourite drink. Demand quality, pay attention to the details, and you’ll find that the draught difference is impossible to ignore.
Frequently Asked Questions
Why does tap beer taste different than canned beer?
Tap beer is typically unpasteurized and kept in a pressurized, light-proof environment, preserving its original flavor profile. Canned beer is often pasteurized to survive long-term storage, which can dull delicate hop aromas and change the mouthfeel. Additionally, the tap system’s CO2/nitrogen mix provides a more consistent, controlled carbonation level than what is possible in most packaged formats.
What is beer lacing?
Lacing refers to the rings of foam that remain on the inside of the glass as you drink. It is a visual indicator of two things: a properly cleaned glass free of oils or detergent residue, and a beer with good protein content and carbonation. If your beer leaves no lacing, the glass is likely dirty or the beer is flat.
How often should beer lines be cleaned?
Professional standards dictate that beer lines should be cleaned every two weeks. This prevents the buildup of yeast, bacteria, and beer stone, which can cause sour or metallic off-flavors. If a bar claims they clean them “occasionally” or “once a month,” you are likely drinking beer that has been compromised by bacterial growth.
Does the glass shape really matter for draught beer?
Yes, absolutely. Glassware is designed to direct aromatics toward your nose and maintain the head. A tulip glass, for example, helps trap the volatile hop aromas of an IPA, while a straight-sided pint glass is utilitarian but offers less aromatic retention. Using the correct glass for the style is the final step in ensuring the brewer’s intent is fully realized in your glass.
