Westwood bottle finishesHistorically, cork sealed bottles needed some sort of covering to prevent the cork being gnawed by rodents or infested with cork-boring bugs. Down through the years the corked end of the wine bottle has been covered and protected, first with wax (slow to apply, hard to remove), lead foils (REALLY bad for landfills and groundwater) and these days with capsules of tin, aluminum, poly-lam or heat-shrink PVC.

In the 21st century it seems to me that if your corks are being chewed on by rodents or weevils you have more to worry about than whether your wine bottles are being stored properly. I’m thinking of doing away with capsules on our wine bottles. To my thinking the capsule has become an affectation, a beauty mark applied with a felt-tip pen.

Getting rid of the capsule is not a revolutionary or even a new idea. Plenty of packages have moved to something else. Like a clear heat-shrink capsule (for goodness sakes why?). Or a neat square finish bottle neck with a tiddlywink of plasticky wax over the end of the cork itself — tough to push a screw through and just begging to flick into someone’s eye at the next table. And I’m pretty sure others have already “gone naked” — Copain Wine Cellars bottlings come to mind. But traditional embossed tin capsules sure are pretty, and I’m wondering how big a slice of the wine-loving world is so married to the look that the lack of a covering would make a difference to them. is naked pretty enough?

Capsule Pros:

  • They look nice.
  • They are part of the traditional, expected wine bottle package.
  • They offer an extra bit of canvas for branding.

Capsule Cons:

  • They are an added and perhaps unnecessary cost — $0.09 to $0.15 per bottle, plus the added labor on the bottling line to apply them.
  • When I make a buy of custom printed capsules the minimum order represents three years of bottling — a significant chunk of change, and a storage requirement.
  • A particular capsule size locks me into using the bottle that fits it properly.
  • They are a recycling burden: they should be removed from bottles before recycling as the tin contaminates the glass cullet, causing a dark brown coloration to the re-melted glass.
  • The tin itself is a valuable recyclable — at nearly $8/lb. it is over ten times the value of scrap aluminum — but recyclers are few and far between.
  • Capsules can be the bane of an elegant tableside presentation of a bottle of wine: they can be hard to cut off cleanly, leaving an unattractive ragged edge, and one can’t tell if the cork has leaked underneath the capsule until it is removed.

The pictures in this post show the variations in Westwood packaging. We have been bottling our 4-Part Rosé since 2005 without a capsule, and so far without a server or consumer complaint. So what do YOU think? I’d really like to hear from my wine-loving friends, brokers, retailers, and especially servers and sommeliers. Is naked beautiful?
