The PerfectDraft experience brings the joy of draught beer straight into any home. But once a keg is opened, the question arises: how long does a PerfectDraft keg last once opened? Understanding this is essential for maintaining freshness and taste throughout the enjoyment period.

Between gatherings, match nights or quiet evenings, a keg may not be emptied immediately. That’s where the PerfectDraft system shows its excellence: beer is kept cool, carbonated and flavourful... without compromise.

The advantage of using PerfectDraft at home

PerfectDraft kegs don’t just stay fresh—they provide consistency. From the first pour to the last, pressure and temperature remain stable. That guarantees a pub-quality experience every time, without the need for complex equipment or homebrewing acumen.

PerfectDraft has developed a system that suits casual enthusiasts and passionate amateurs alike. Whether experimenting with styles or revisiting a favourite brew, the machine offers reliability and a certain peace of mind.

Thanks to the sealed keg design, waste is reduced. No more half-drunk bottles going stale. Just well-poured pints when the mood strikes—day after day, week after week.

It’s no surprise that many choose PerfectDraft for social events. No waiting, no fuss, and most importantly: fresh beer that keeps its bouquet and sparkle for weeks.

How long does a PerfectDraft keg last once opened?

Once installed in the machine, a PerfectDraft keg can stay fresh for up to 30 days. This performance is due to the integrated cooling and pressurisation technology that avoids oxidation and contamination. The beer remains crisp and enjoyable over the weeks.

Yet, external factors matter. If the keg is removed and stored improperly, its lifespan shortens. The optimal conditions provided by the machine must be maintained to ensure the beer doesn’t lose its subtle flavours.

Unlike open bottles or cans, which quickly degrade, PerfectDraft offers a sealed environment. That makes it ideal for moderate drinkers or those who savour different styles slowly... No rush to finish a keg in a weekend.

It’s important to remember: the 30-day guideline applies when the keg remains in the machine at a consistent temperature. That’s a reassuring duration for anyone valuing taste over haste.

Factors influencing how long beer stays fresh in a keg

The most vital factor is temperature. The PerfectDraft machine cools beer to 3°C, preserving taste and carbonation. Any exposure to heat may lead to spoilage, especially if the keg is taken out mid-use.

Hygiene also plays a role. Clean tap lines and proper machine maintenance help avoid off-flavours and microbial degradation. Regular upkeep ensures the freshness window is fully maximised.

Another element: beer style. Some brews with high hop content or unfiltered yeasts may evolve slightly over time, although the sealed keg protects them far better than open containers.

And of course, air exposure is eliminated with PerfectDraft. Unlike classic home systems that rely on CO₂ cartridges or manual pours, our system prevents oxidation entirely—ensuring a longer freshness period.
