What Wine Pros Want You to Know About Screwtops (Hint: They’re Totally Worth Buying)

A screw cap isn’t a shortcut or a downgrade—it’s simply another method of sealing wine, and one that many respected producers now prefer because it protects flavor with remarkable reliability.
For most wines intended to be enjoyed within a few years, screw tops are often the more practical choice, helping preserve the winemaker’s original intent from bottle to glass.
They also bring everyday convenience: easier opening, simple resealing, and fewer headaches overall, while cork still plays an important role in select age-worthy wines.

There’s something undeniably ceremonial about pulling a cork. Whether it’s a sommelier presenting a special bottle in a restaurant or a quiet celebration at home after an ordinary Wednesday, that small pop carries a sense of anticipation. It’s a ritual, and mastering it can even feel like a subtle badge of confidence.

By contrast, a screw cap can seem almost anticlimactic—too quick, too effortless. For years, that simplicity was misread as a signal of lower quality. But that assumption doesn’t hold up under closer inspection. In fact, as I learned while exploring why producers in Italy’s Lugana region are increasingly adopting screw caps, the reality is far more nuanced. The closure says little about prestige and much about precision. For many wines, aluminum screw caps may actually be the more reliable guardian of quality.

Quality Control
To understand the divide between cork and screw cap, it helps to know what cork actually is. Harvested from the bark of cork oak trees, cork is a natural material—and with that comes variation. As sommelier Dana Beninati explains, even when shaped for bottling, cork retains a degree of porosity and flexibility. That natural inconsistency means the seal isn’t always perfect.

If the fit is slightly off, oxygen can slip in quietly over time. Beninati describes this as wine’s quiet adversary. In most cases the effect is minimal, but when things go wrong, it becomes obvious: so-called “corked” wine can develop off-putting aromas reminiscent of damp cardboard or wet wool.

Screw caps, by contrast, create a far tighter seal. Aluminum closures dramatically reduce exposure to oxygen and eliminate the risk of cork taint altogether, notes Ambra Berardi, who works closely with producers in Lugana. In her view, it’s less about tradition and more about technical control.

That shift is already visible in Lugana, where a growing number of wineries are rethinking their approach. Some have moved entirely to screw caps, while others now split their production, offering both closures depending on the wine’s style and purpose.

Consistency
Beyond avoiding cork-related faults, consistency is one of the strongest arguments in favor of screw caps. Beninati points out that the vast majority of wines worldwide are designed to be consumed within about five years. In that window, stability matters more than slow evolution. Screw caps help ensure the wine tastes the same in the glass as it did in the cellar.

Still, cork hasn’t lost its place. It remains better suited to certain wines that are crafted for long aging and gradual transformation. As Berardi explains, the closure should match the wine’s intention: bright, aromatic whites often benefit from the clean neutrality of screw caps, while structured, age-driven bottles may still lean on cork’s subtle oxygen exchange to develop complexity.

Beninati agrees, noting that wines built for long cellaring—such as prestigious Bordeaux-style reds or certain traditional sparkling wines—can benefit from cork’s slow, controlled interaction with air.

Ease and Sustainability
There’s also the simple matter of convenience. Anyone who has struggled with a stubborn cork—or watched one crumble mid-extraction—can appreciate the frictionless ease of a screw cap. No tools, no tension, just a clean twist and pour.

Screw caps also make storage easier, offering a resealable option that fits neatly back into everyday life. Refrigerators, travel, and leftovers all become less complicated when the closure actually works with you instead of against you.

From an environmental perspective, Berardi also highlights that modern screw caps are highly recyclable, challenging the assumption that natural automatically means more sustainable.

The Bottom Line
The idea that screw-capped wines are inherently inferior is increasingly outdated. As Berardi notes, many respected producers across regions like Austria and New Zealand—and now parts of Italy—have embraced screw caps not as a cost-cutting measure, but as a deliberate technical choice. It’s less about tradition versus modernity and more about protecting the wine’s character with precision and consistency.
